| 07:59.35 | hno | slapin_, odd. There should be no other SRAM, and it need to buffer the data to do ECC. |

The gist of my current understanding is that you install tool chain to compile kernel for the CPU in already working Lubuntu such as the MK802, and then after that its a blank. |
| 09:38.53 | focus_well | I have installed the tool chain and it compiled Gambas (a GUI program like VB) from sources so I know compiler bits at least work. |
| 09:39.03 | focus_well | Do I now download and compile https://github.com/linux-sunxi/linux-sunxi/archive/sunxi-3.0.zip before I take any more steps? |

| 09:42.32 | hno | focus_well, you need a userspace root with a bash prompt. |
| 09:43.23 | focus_well | hno: is that something I compile and build, or is that something that is available pre-built? |
| 09:43.49 | hno | the lubuntu one you have is a candidate. |
| 09:44.41 | hno | focus_well, I would recommend playing a bit with qemu to learn the boot procedure, kernel arguments etc. |
| 09:45.49 | slapin | hno: NAND NAND NAND, might you play a bit with code on pastebin? |
| 09:45.51 | focus_well | hno: hmmm.. I used qemu a long time ago, is there a qemu image for the A10? |
| 09:47.05 | hno | focus_well, your question is mostly architecture neutral. You can use x86 while learning to speed things up. |
| 09:48.58 | focus_well | hno: I have 2 MK802s to play with and a couple of 8GB uSD cards. So real hardware is not a problem. |
| 09:49.55 | hno | focus_well, it's much quicker doing this with a VM. But you can do it using real hardware ans swapping cards if you like. |
| 09:50.35 | hno | I would wait with the hardware until you have a basic understanding of how booting Linux works. |
| 09:51.53 | focus_well | hno: real harware I prefer. So basically you tell get the linux, put onto uSD, and find a way to make that boot into bash. Other pray hard until your prayers are answered? |
| 09:52.14 | focus_well | Otherwise pray hard? |
| 09:52.16 | hno | There is no praying needed. Only doing. |
| 09:52.42 | focus_well | Good :-) |
| 09:52.47 | focus_well | Thats progress! |
| 09:53.20 | hno | But you need to have a understanding of what is bootloader, kernel, initramfs, rootfs, userspace. |
| 09:53.40 | focus_well | hno: I have good understanding linux |
| 09:53.59 | focus_well | but insufficient detailed knowledge of the bits that connect everything together |
| 09:54.02 | cheng | the better way is have a good understanding of each steps (at least it make senses to you) before going hands one |
| 09:54.13 | cheng | hands on. |
| 09:54.51 | hno | focus_well, so you are familiar with kernel command line, rood fs specifications, how to make a rootfs, how to build a kernel? |
| 09:55.13 | hno | and how to make an initramfs? |
| 09:55.59 | focus_well | its no to all, I only know about them, the boot loader I know a bit more about because I make SDCard read/write hardware and software |
| 09:57.12 | hno | then spend an hour on learning these things. It helps a lot. Kernel compile is not the important. |
| 09:57.26 | focus_well | very detailed knowledge about sectors and registers for controlling SDcard |
| 09:57.50 | hno | that is not needed. software already take care of the register details. |
| 09:58.10 | focus_well | so I guess the next step is getting the boot sector to boot a linux |
| 09:58.41 | focus_well | or is the bootloader that I have to inform as the boot loader already knows how to read sdcard |
| 09:59.58 | hno | Both CPU, bootloader and kernel knows how to read sdcard. |
| 10:00.59 | hno | I assume you have UART console? |
| 10:02.36 | focus_well | I got PC, and USB to serial, so I assume I can wire some pins to A10 to get UART console? (Sorry to ask I am out of my depth here with A10 hardware for now.) |
| 10:03.59 | hno | Ok, back to learning desk then. Don't dive into this on real hardware without console access. |
| 10:04.14 | focus_well | hno: my plan was I got MK802, so do everything on uSD and then get my own A10 to boot from uSD. The A10 will go on a SO-DIMM 200 pin card and it will have on it the uSD socket |
| 10:04.57 | focus_well | MK802 I can buy for $30 - so buy 10 if need be! :-) |
| 10:05.17 | focus_well | I did not want console based programming |
| 10:05.44 | hno | focus_well, sure. And it only have UART on small test pads so it will take you some time to get the console running on each. |
| 10:06.09 | hno | plus you need to be careful so you actually get an A10 based one. MK802 exists in many flavors. |
| 10:06.45 | hno | Having console access is critical to understanding these things. |
| 10:08.05 | focus_well | I know console is good, but I saw an opportunity when I note A10 can boot directly from SD. if I have a working MK802, then perfect everything by swapping code between different uSD cards |
| 10:09.06 | hno | focus_well, without console you are blindfolded. Everything must be close to 100% right before you see any output on HDMI. |
| 10:10.54 | focus_well | hno: I take in your advise. I like the blindfold. What I was going to do is run Linux and get a small program to flash LED. That way I know it booted and doing things. I am aiming for 5" LCD instead of HDMI - because the board won't have HDMI. |
| 10:11.27 | hno | LCD is even more complex to get right than HDMI. |
| 10:11.28 | focus_well | Once I got LCD to show a bash prompt, nothing to hold me back |
| 10:11.50 | focus_well | I got LCD I make work with other ARM - non Linux software |
| 10:12.49 | focus_well | So it is a matter of configuring LCD driver for Linux with the LCD I know works, and getting Linux to boot to bash |
| 10:13.34 | focus_well | hno: if things get really difficult I get console working |
| 10:13.55 | hno | OlinuXIno A13 probably a better dev platform for you than MK802. And maybe A13 is even the better choice of CPU if you only want LCD. |
| 10:14.33 | hno | max 512MB memory, no HDMI. no LAN, no SATA. |
| 10:14.37 | focus_well | The A13 RAM is limiting - 512MB |

| 10:45.37 | hno | slapin, no battery pins in this generation. |

| 10:46.35 | slapin | hno: too bad, I'd like to play with a battery on cubieboard :( |
| 10:47.11 | hno | A10 SATA connects fine to SATA RAID boxes with built-in RAID. It does not work with port multipliers however. |
| 10:47.21 | slapin | hno: about NAND - can you please make your opinion on reading stuff? |
| 10:47.54 | slapin | hno: my eSATA "raid" box is really multiplier. |
| 10:48.07 | slapin | hno: is it hardware or software issue? |
| 10:48.45 | hno | I don't have much idea on what is going on with the NAND read commands. But don't see that the controller should make much difference. |
| 10:49.03 | slapin | hno: what requirements are to work with multipliers? I use dreamplug, where multipliers work, and don't see there any special support. |
| 10:49.23 | slapin | hno: do you have an oscilloscope or logic analyser? |

| 10:51.47 | slapin | hno: no other clients? |
| 10:52.39 | hno | there is a python client, but it is very basic and do not support compression so it's hard to capture high frequency signals. |

| 11:15.33 | slapin | hno: doesn increasing dividers help? |

| 14:28.16 | oliv3r | to more techincal stuff; what does AHB clock gating' do? or clock gating in general? |
| 14:28.23 | oliv3r | simply 'enable/disable' the clock to a device? |
| 14:28.31 | slapin | oliv3r: yes |
| 14:28.44 | slapin | oliv3r: actually disabling/enabling clock passing |
| 14:28.46 | oliv3r | so the 'missing' clock gates can be figured out by trying and seeing what does or does no longer work? |
| 14:28.47 | mnemoc | oliv3r: semantically it makes more sense the cubieboard2 to have the double of extensions, and the cubieboard4 to have the quad core soc |
| 14:29.16 | oliv3r | slapin: so basically its a transistor that allows the clock signal to pass or not |
| 14:29.17 | mnemoc | to give some meaning to the number |
| 14:29.27 | slapin | oliv3r: might be so |
| 14:29.29 | oliv3r | mnemoc: cubebieboard++ |
| 14:29.37 | oliv3r | slapin: in 'laymans terms' i ment :) |
| 14:29.59 | oliv3r | i just ask, because there's no clock gating defined for things like AC97, SPDIF, keyboard etc |
| 14:30.11 | slapin | oliv3r: it is usually several components, but yes |
| 14:30.13 | oliv3r | and some spots where they could very well be hiding in the gating register |
| 14:30.36 | slapin | hmmmmm |
| 14:30.54 | oliv3r | hmm, the doc is quite specifc, anyway, what triggerd me, is there are timer registers for said components, but no gating entries in the gateing registers, BUT there are holes in the gating registers |
| 14:31.03 | oliv3r | (page 47 and 48) |
| 14:31.31 | oliv3r | so by disabling/enabling certain gates, the ac97/spdif etc gates should be 'findable' |
| 14:31.59 | slapin | oliv3r: or not |
| 14:32.11 | slapin | oliv3r: depends if there are any gates |
| 14:32.12 | oliv3r | slapin: :( |
| 14:32.33 | oliv3r | well there's some 'reserved holes' e.g. 'we don't want you to see this' in the docs and some aren't even in the src |
| 14:32.41 | oliv3r | well not in ccmu_regs |

| 14:33.35 | slapin | which of these meles is a2000g? |
| 14:33.48 | oliv3r | slapin: yeah most of it is in the source, but some isn't in the source either, so they are just 'hiding' it? |
| 14:34.02 | oliv3r | slapin: there is only an a1000g i belive, and hipboi said it's not visible in the front yet |
| 14:34.09 | oliv3r | probably has to replicate across the frontend mirrors first |
| 14:34.13 | oliv3r | i am guessing |
| 14:34.32 | hno | slapin, need a picture of the board to be able to help locating serial. |
| 14:35.15 | mnemoc | slapin: aliexpress moderates new products, the a2000g is not just published on the catalog |
| 14:35.56 | stefanro | hno: might be that i can find some time for the sr32 cleanup - which branch is the one i should use? |
| 14:36.29 | slapin | mnemoc: any direct links? |
| 14:36.42 | mnemoc | slapin: only after it passes moderation |
| 14:36.48 | slapin | :( |
| 14:37.06 | slapin | I will spend all my money by then :( |
| 14:37.10 | oliv3r | i wanna buy now! |
| 14:37.19 | hno | oliv3r, ther is schematics, full board layout CAD drawings and component supply available for nexus 10? |
| 14:37.31 | mnemoc | "it for your own safety" (tm) |
| 14:38.01 | oliv3r | hno: of course not, they where talking software! the statement up above claimed 'full' meaning software too |
| 14:38.14 | oliv3r | safety? pff! safety is for wussies! |
| 14:38.34 | mnemoc | oliv3r: if you ignore the gpu and vpu, software is 100% free/open |
| 14:39.05 | mnemoc | and those two are on the road of been REed |
| 14:39.27 | slapin | got a cruel plan building A13 "stick" using components from balcony, olimex, and building board at iteadstudio.com |
| 14:39.48 | hno | oliv3r, what missing AHB gates? |
| 14:39.49 | mnemoc | slapin: the a13 is awful for an stick |
| 14:40.04 | slapin | this is far cheaper than building S3C24xx boxes |
| 14:40.26 | slapin | mnemoc: I solder large BGA packages very badly |
| 14:40.35 | mnemoc | S3C24xx is so 4ya |
| 14:40.40 | *** join/#arm-netbook cheng (~cheng@124.13.188.160) |
| 14:41.12 | hno | oliv3r, see clock diagram in the datasheet (short version with pinout) |
| 14:43.19 | hno | stefanro, always sunxi-current if you want a sane life with git. sunxi-patchqueue also works but is continously rebased. |
| 14:43.37 | slapin | mnemoc: A13 is TQFP, and I can solder RAM chips |
| 14:43.40 | stefanro | hno: okay, thats what i thought |
| 14:45.34 | hno | is not entirely comfortable with TQFP of the spacing & size of A13, but could probably do it. |
| 14:46.08 | oliv3r | hno: ac97 clock gates |
| 14:47.00 | oliv3r | hno even the short datasheet has things like 'NC-CLK' under the nand-clk which I think was sata clk iirc (see linux-sunxi.org/A10/CCM top section) |
| 14:47.12 | oliv3r | or the IIS-clk combined with a nother 'NC' clock |
| 14:48.10 | oliv3r | slapin: good plan, I've solderd a GDDR ram module too, solderd the pads, put chip on, used hot air blowdryer to 'melt' it in place :) |
| 14:49.16 | oliv3r | hno: and finally, KEYPAD-CLK shows up in the diagram, but is 'missing' from CCM_AHBCLK_GATE[01] in source |
| 14:52.04 | L84Supper | mnemoc: so what I think you are saying is that is other than all the closed stuff it's all open |
| 14:52.13 | hno | oliv3r, KEYPAD & AC97 is on APB |
| 14:52.57 | mnemoc | L84Supper: only that all closed stuff in the a13-olinuxino is optional |
| 14:53.48 | mnemoc | L84Supper: and that eventually those will be open too |
| 14:54.05 | oliv3r | hno: ah! (Wasn't that far yet :p) |
| 14:54.26 | oliv3r | mnemoc: eventually :( Faster! Faster! :) sorry, i'll get back to work |
| 14:54.59 | hno | oliv3r, there is several different logic busses depending on the speed of the pheriperal. |
| 14:55.07 | pucko | gah... I lost the URL for the Mele Debian armhf image... anyone remembers? |
| 14:55.34 | hno | oliv3r, most peripherals also have a function clock. |
| 14:56.10 | hno | both clocks are needed for operation. The bus clock controls the CPU facing side (registers etc) and the function clock the operation of the device. |
| 14:57.03 | oliv3r | ah, dual facing I didn't know |
| 14:57.42 | hno | the bus clock is only gated. function clocks have divisors |
| 14:58.01 | L84Supper | is somebody working on reversing the video decoder/accel in the a10/13? is that part of Lima? |
| 14:58.15 | hno | and some pheripherals have additional clocks derived by th |
| 14:58.29 | hno | their own. |
| 14:59.24 | oliv3r | so you enable/disable the clock (gate) on the CPU facing side; and you setup devisors for the perp. facing side, check. I may write a little abbout that on the wiki |
| 14:59.31 | hno | i.e. UART have a baud rate clock divisor dividing the UART function clock to a sensible baud rate. |
| 14:59.43 | oliv3r | L84Supper: ian ... i forgot, he posted on the ML and on g+ |
| 15:00.08 | L84Supper | http://linux-sunxi.org/CedarX#Reverse_Engineering |
| 15:00.58 | oliv3r | that |
| 15:01.10 | L84Supper | so allwinner is shy when it comes to sharing any of this source |
| 15:01.38 | hno | shu of sharing any source currently :( |
| 15:02.08 | L84Supper | nothing like building trust :) |
| 15:02.25 | L84Supper | maybe Luke just heard them wrong last year :) |
| 15:03.33 | hno | L84Supper, no, lkcl knows where they stand. |
| 15:03.45 | L84Supper | "sure we will share all the source with you in exchange for community support..... except for big chunks of it" |
| 15:04.27 | hno | for the A10 the situation is reasonable. The SDK have full kernel & u-boot sources. |
| 15:04.30 | oliv3r | i think once linux-sunxi work becomes more known and more used, it may trigger allwinner into seeing that what is happening here is a good thing (for them) |
| 15:05.35 | L84Supper | oliv3r: maybe, I haven't met any of them or checked into their backgrounds. I wonder what their track record was like with their management before. |
| 15:05.58 | L84Supper | is it the same team as Boxchip? |
| 15:05.59 | hno | oliv3r, maybe. But it's too late for any serious effect. Allwinner already had their boom with A10 sales. Now focus is on next generation. |
| 15:06.07 | hno | L84Supper, should be. |
| 15:07.05 | hno | with some adjustments from being several companies merged together. |
| 15:07.20 | L84Supper | hno: I agree, they should be giving all the source away for the A10 now that it's old. What's left to control? .... unless you have issues with control |
| 15:07.53 | oliv3r | hno: that may be true, but A40 may be very close related so could get a jump start |
| 15:08.13 | oliv3r | sad but true, linux-sunxi will just follow after the facts and nothing exciting will happen in the industry |
| 15:08.16 | mnemoc | L84Supper: lichee2/2.6.36 was released once totally obsoleted by lichee3/3.0.8 |
| 15:08.20 | hno | L84Supper, they already have given away as much source as they can realistically do. |
| 15:08.31 | oliv3r | libcedarx! |
| 15:09.15 | mnemoc | Turl: did you decide to take vaapi or REing cedarx as univ. project? |
| 15:09.17 | L84Supper | hno: since GPU and video decoder source is under NDA from ARM? |
| 15:09.33 | hno | cedarx is still their main IP. |
| 15:09.48 | hno | The MALI GPU is under NDA from ARM. |
| 15:10.22 | L84Supper | is the video decoder/accel (mpeg, h.264 etc decoder) part of mali? |
| 15:10.33 | mnemoc | L84Supper: that's cedarx, not mali |
| 15:10.56 | L84Supper | where do they get the cedarx block from? |
| 15:11.15 | hno | cedarx video & audio codec is their is considered their main IP block, what sets the company apart from others. |
| 15:11.35 | L84Supper | did they design it themselves? |
| 15:11.50 | hno | full history is unknown, but it's been part of their whole series of CPUs, noticeably improved with each generation. |
| 15:12.18 | L84Supper | oh ok, and they won't share source for those blocks, got it now |
| 15:12.25 | slapin | I don't know how this all is related to closed drivers |
| 15:13.03 | slapin | I understand they don't want to share their IP blocks, but drivers are just controlling interface... |
| 15:13.14 | hno | slapin, acceleration hardware and software using it goes in tandem. |
| 15:13.17 | L84Supper | so if someone were to reverse the cedarx it would give some of what they consider 'secrets' away to how to build the multimedia IP blocks |
| 15:13.58 | slapin | I don't think I will understand anything re IP blocks building from looking at driver source... |
| 15:14.11 | L84Supper | now I'm starting to understand the pathology |
| 15:14.17 | slapin | I don't even know what NAND controller thinks now. |
| 15:14.36 | hno | slapin, IP concept also covers software. |
| 15:15.33 | L84Supper | part of the reasons why register specs are not shared is that it provides evidence of how the hardware works and what patents might be violated |
| 15:15.57 | oliv3r | mnemoc: vaapi? what happened to openmax! |
| 15:16.08 | focus_well | hardly true about IP secrets - everyone knows how to build multimedia blocks - all they loose are sales if their chips are not selling |
| 15:16.22 | L84Supper | it could easily be covered by just moving some registers around but that's too much work for some ASIC teams |
| 15:16.31 | focus_well | http://www.ipcores.org has lots of IP all open source |
| 15:16.40 | slapin | L84Supper: if you cover video you 100% know that hundreds of patents are violated, just knowing it is video decoder which is not paid to MPEG LA |
| 15:17.11 | libv | L84Supper: ? |
| 15:17.25 | libv | L84Supper: there's millions to be earned by patent cases |
| 15:17.58 | libv | L84Supper: it's trivial enough to RE one of these blobs, and point out to a judge if it is violating some patents, especially given the amount of money, and this REing time available |
| 15:18.13 | focus_well | The best way around mpeg is to create your own alternative video formats and support one for sure and edge out the closed ones |
| 15:18.37 | libv | focus_well: and now for the real world... |
| 15:19.04 | focus_well | that means a bit of VHDL to add into the cores and then some software to use it |
| 15:19.12 | slapin | focus_well: many patents are not algorithm or format related, they cover whole process of video decoding and encoding |
| 15:19.13 | L84Supper | yeah, they aren't going to support a proprietary standard |
| 15:19.54 | libv | again, the availability of code does not help with IP issues |
| 15:20.10 | focus_well | libv: we all make money eventually doing our own open source projects - so all it needs is one or more persons to invest in this in organized way to phase out locked systems |
| 15:20.27 | libv | focus_well: go at it. now. |
| 15:21.11 | focus_well | libv: I sure will - just starting out on freeing up the KiCAD designs for modular SO-DIMM PCBs and after that who knows |
| 15:22.06 | focus_well | the money is mine but designs are of no use to me after they are built so I give them away |
| 15:22.47 | slapin | any available design on 72-pin SIMM module for KiCAD, and is DRAM chips are available? my AXPpci board is collecting dust without memory :( |
| 15:23.43 | focus_well | not that I know of - I'm just starting out - I don't know where it take me |
| 15:23.44 | oliv3r | there, lots of stuff up on the wiki. so much my fingers hurt now! More tomorrow maybe :) |
| 15:23.45 | mnemoc | he is designing SoMs, not DRAMs |
| 15:23.47 | L84Supper | the a10 was successful because of its features at a low price.... |
| 15:24.25 | libv | oliv3r: :) |
| 15:24.32 | focus_well | mnemoc: interchangeable SoMs so if one manufacturer falls over then switch to another one |
| 15:24.53 | L84Supper | the main cost of developing an ARM SOC is the ARM cpu + GPU license + the other IP blocks you buy (and the masks) |
| 15:24.55 | focus_well | that way those who can't open source their drivers will sooner fade |
| 15:25.10 | oliv3r | well until the a40 comes out, the a10 will remain successful. if the a40 has the same pinout as the a10; it will be an instant success imo |
| 15:25.37 | focus_well | L84Supper: there is new CPU + Linux all running on open VHDL code at opencores.org - no need for arm |
| 15:26.06 | oliv3r | problem with opencores, you need to be able to manufacture said CPU's |
| 15:26.10 | mnemoc | focus_well: are you designing also some boards where to put these SoMs? |
| 15:26.23 | L84Supper | focus_well: I don't think people are interested in supporting those cores |
| 15:26.25 | oliv3r | and that requires quite a lot of money (and quite some expertise). BUT I agree, in the far future, aboslutly |
| 15:26.45 | oliv3r | L84Supper: they will be, once you can actually buy hardware with those cores |
| 15:26.46 | slapin | hno: http://ossfans.org/mk802_1G/ |
| 15:27.09 | mnemoc | oh, a real antenna |
| 15:27.15 | focus_well | oliv3r: they run on fpga - and if you got about $30,000 to $250,000 you can have your own chip |
| 15:27.20 | L84Supper | oliv3r: which core? |
| 15:27.32 | slapin | mnemoc: where? |
| 15:27.39 | slapin | mnemoc: antenna? |
| 15:27.43 | mnemoc | slapin: in your pictures |
| 15:27.46 | L84Supper | MIPS? |
| 15:27.48 | oliv3r | L84Supper: cores -> soc and then ... win! |
| 15:27.58 | oliv3r | L84Supper: Isn't the sparc II design open? |
| 15:28.39 | oliv3r | Oh! Nand clock, for tomorrow! exciting stuffs :) hoemtime now :) |
| 15:28.40 | slapin | mnemoc: I seen better antennas in my practice. I have the same in A7HD, had to fix it to work... |
| 15:28.45 | focus_well | mnemoc: I got a mboard that can take the SoM and break out to LCD, SD, some breadboard area, and power supplies |
| 15:29.03 | L84Supper | China went with a MIPS variant for their supercomputer CPU core |
| 15:29.18 | slapin | L84Supper: MIPS is dead now |
| 15:29.31 | L84Supper | not it China |
| 15:29.36 | focus_well | L84Supper: I rather the existing cores and then win but if they be stubborn, then yes cores > soc > win |
| 15:29.39 | slapin | L84Supper: hope so |
| 15:29.45 | L84Supper | http://en.wikipedia.org/wiki/ShenWei#ShenWei_SW1600_Microprocessor |
| 15:30.30 | L84Supper | how to crowd source $5M USD for masks? |
| 15:30.49 | slapin | well, some of Chinese hw vendors use open cores, like OpenRisc in their products. e.g Jennic old "Zigbee" modules |
| 15:30.51 | focus_well | its not $5M for masks |
| 15:30.59 | L84Supper | lets say you wanted to use all open cores IP, who could you get to fund the fab? |
| 15:31.18 | slapin | well, you can start with FPGA |
| 15:31.22 | L84Supper | slow |
| 15:31.27 | L84Supper | expensive |
| 15:31.33 | focus_well | about 9months of funding for about 5 people and about $250,000 |
| 15:31.40 | L84Supper | or would lots of people want that? |
| 15:31.47 | slapin | if you need FPGA anyway, then you can use open cores for development speedup |
| 15:31.54 | focus_well | correct |
| 15:32.04 | focus_well | everything is normally done in fpga first |
| 15:32.12 | L84Supper | that not my point |
| 15:32.16 | focus_well | then it goes to chip maker |
| 15:32.30 | focus_well | chip maker takes 9 months and about $30,000 to make wafer |
| 15:32.43 | L84Supper | what geometry? |
| 15:32.48 | focus_well | need the rest for staff of about 5 for 9 months to 1 year |
| 15:33.11 | L84Supper | you're talking about FPGA to asic |
| 15:33.16 | L84Supper | nevermind |
| 15:33.21 | L84Supper | you're new to this |
| 15:33.22 | slapin | there are mask asics which are cheaper, but limited. |
| 15:34.04 | L84Supper | if you really want the performance and price of an FPGA then there's nothing stopping you |
| 15:34.06 | focus_well | or you go to fabless houses and just give money |
| 15:34.40 | focus_well | they have experts but you may end up paying a little more |
| 15:34.41 | slapin | many companies who make instruments (expensive hw, low quantities), use FPGAs for functionality, and use open cores. |
| 15:35.20 | focus_well | say $300,000 for a fabless house |
| 15:35.25 | L84Supper | my point was trying to build an SOC at 28nm |
| 15:35.39 | slapin | hno: about serlal on mk802 |
| 15:36.00 | focus_well | 28nm only if building low power |
| 15:36.07 | L84Supper | I don't think that you'll get lots of support for a FPGA soc |
| 15:36.30 | focus_well | FPGA SoC exists on opencores.org they sell it |
| 15:36.38 | L84Supper | focus_well: who is going to want one that isn't? |
| 15:36.46 | focus_well | I bought one! |
| 15:36.48 | focus_well | :-) |
| 15:36.52 | L84Supper | very few |
| 15:37.26 | focus_well | Its working so I bought one - but expensive and FPGA so much more involved |
| 15:37.45 | slapin | there are lots of cheap FPGAs |
| 15:37.58 | slapin | for $5-$10 |
| 15:38.07 | focus_well | but nothing stopping anyone taking that to a fabless house and turning it into some dice and getting it bonded to a PCB and selling it |
| 15:38.14 | slapin | and they can run OpenRisc and some video cards |
| 15:38.22 | L84Supper | sure, some even have a hard M3 core, so whats the problem? :) |
| 15:39.00 | L84Supper | 100 MHz M3 core should be fast enough for anyone :) |
| 15:39.33 | focus_well | But if you got the sources for the VHDL you can put down 10 on same chip |
| 15:39.43 | slapin | L84Supper: put 10 of them into 1 FPGA and make cluster? |
| 15:39.49 | focus_well | yup |
| 15:40.09 | L84Supper | lets say I had all the VHDL or could write more |
| 15:40.30 | L84Supper | who would fund the mask? |
| 15:40.32 | focus_well | some guy is doing a $99 cluster of 60+ CPUs - kickstarter project - got $700,000+ funding |
| 15:40.58 | focus_well | don't know which cpu |
| 15:41.00 | hno | slapin, http://ossfans.org/mk802_1G/20121114_001.jpg the two pads below the CPU are almost certain UART0 RX&TX. |
| 15:41.28 | slapin | I think crosdfinding some SoC would be interesting experience |
| 15:42.07 | slapin | hno: the ones near USB? |
| 15:42.18 | focus_well | that what I think, one of us make it big, don't forget your roots, and fund an open CPU with open VHDL and Linux |
| 15:42.19 | slapin | I mean wifi usb |
| 15:42.59 | focus_well | if you make money, you can't take it with you, so spread it around on open sourced projects :-) |
| 15:43.38 | hno | <PROTECTED> |
| 15:43.41 | L84Supper | focus_well: I wish there were enough people interested in purchasing such devices |
| 15:43.55 | slapin | focus_well: you can spend all money on vodka and girls, unlimited amounts of money. |
| 15:44.11 | focus_well | i'd be bored i tell ya! |
| 15:44.23 | L84Supper | what most people seem to want is either a status symbol or cheapest that works even if it's closed |
| 15:45.10 | hno | slapin, yes those two. You need to find GND elsewhere, preferably not the same spot you wire the wireless module.. |
| 15:45.34 | slapin | L84Supper: enough people buy mk802, and its usefulness is questionable, so there will be enough people for open CPU, of properly adverticed. |
| 15:46.28 | L84Supper | slapin: have any references I could show to a bank, investors, venture cap. etc etc? |
| 15:46.40 | slapin | L84Supper: you can say in your ad, that successful people use only open SoCs/CPUs and it will become status symbol. |
| 15:46.41 | L84Supper | I just don't see the numbers adding up |
| 15:47.16 | focus_well | whats missing is a linux + LCD module that runs gambas (a VB like program). That can go into any machine. I got MK802 with Gambas working. |
| 15:47.18 | L84Supper | heh, I'm all behind you trying that |
| 15:48.12 | focus_well | So all I need to do is put it into SoM and make available drivers for 3", 4", 5", 7", 10" LCDs |
| 15:48.35 | slapin | L84Supper: if you don't see a numbers, make fake ones. |
| 15:48.49 | L84Supper | if the RaspberryPi has to fab their own device they would't be breaking even yet |
| 15:49.03 | L84Supper | has/had |
| 15:49.16 | slapin | focus_well: don't forget of quite popular 1.5" and 2", 2.2" |
| 15:50.00 | slapin | L84Supper: RaspberryPi has good sponsors, no? |
| 15:50.01 | focus_well | The MK802 image is here (not for public release) http://www.gplsquared.com/mk802/mk802.html with gambas3 working and a sample program that boots up. The sample program can even talk! |
| 15:50.21 | hno | L84Supper, Infrant used an open core in their CPU which was used in ReadyNAS. Later bought by Netgear. They switched to an off the shelf ARM cpu & X86 models nowdays however, mostly because there now is suitable and not too expensive ARM CPUs for their market. |
| 15:50.22 | traeak | hehe |
| 15:50.29 | slapin | feels bad about talking programs/computers |
| 15:50.30 | focus_well | to make it talk - just type into the box below the talk button and press the button - it comes out the HDMI speakers |
| 15:51.01 | traeak | i wish the fpgas were cheaper |
| 15:51.19 | focus_well | The program is serial port communications - so if you send it RS232 data, it logs it to a file. If you send the data with <s> text </s>, it will parse it and talk that bit |

| 15:52.16 | L84Supper | organize the community, show a vendor that they will make $$ by making open hardware, if its real they will do it |

| 15:52.51 | traeak | focus_well: point taken, it's a technology thing |

| 15:54.27 | focus_well | L84Supper: I intend to release the SoM KiCAD, and that will allow anyone to put their chip to a SoM and get it talking to LCD - instant winner |
| 15:55.09 | focus_well | With gambas running on it, they can use like VB and design their applications very quickly and get it on to the SoM and make money |
| 15:55.22 | hno | focus_well, FPGAs are very cheap compared to not having FPGAs |
| 15:55.40 | focus_well | Of course, if other chip makers want in, they need to their SoMs |
| 15:55.44 | focus_well | and Linux |
| 15:55.48 | focus_well | and LCD :-) |

| 21:49.54 | traeak | not very usefulwhen empty |
| 21:50.03 | rm | it NOPs fsync, which rm might do a bit too often; in any case this seemed to help on btrfs |
| 21:50.12 | libv | in some sense, yes, but at least they picked the SoC which currently comes closest |
| 21:50.26 | drachensun | my thoughts exactly, sure its not perfect |
| 21:50.34 | libv | but really, /., pffff |
| 21:50.40 | libv | what are these guys smoking |
| 21:50.42 | traeak | lundman: what kind of stuff is going on the storage? |
| 21:50.56 | libv | and now on to real work :) |
| 21:50.57 | drachensun | but when I looked at all the other SOC's this has the best community support and most available source |
| 21:51.14 | traeak | drachensun: that's a pretty sad state of affairs |
| 21:51.25 | libv | drachensun: yeah, and then notice all the RPi fanboys on /. |
| 21:51.39 | libv | they still do not want to own up to the fact that the videocore runs the whole show |
| 21:51.47 | drachensun | traek: No argument :) |
| 21:52.07 | slapin | TI SoCs are a bit better supported, but these are a bit harder to get... |
| 21:52.11 | hno | well, 2K in total, but the upper half seems to be mostly used for collecting spare data. |
| 21:52.14 | traeak | i dumped my rpi off to some sucker, got almost what i paid for it. |
| 21:52.20 | traeak | s/to/on/ |
| 21:52.31 | drachensun | yup, similar state for the video drivers, its much slower and you cant get it in tablets or netbooks as far as I know |
| 21:52.37 | drachensun | without hacking your own device together |
| 21:52.40 | hno | slapin, Allwinner uses a randomizer in all written data I think. |
| 21:52.51 | Turl | pretty much the only way to get an OMAP is with pandaboard/beagleboard |
| 21:53.03 | Turl | (in board format that is, you could buy a phone too) |
| 21:53.04 | drachensun | slapin: The sad thing is TI wont even sell you there current gen stuff |
| 21:53.13 | slapin | hno: is randomizer predictable? |
| 21:53.24 | drachensun | and sitara processors are VERY expensive in comparison to the chinese ones |
| 21:53.27 | hno | It's seeded in the ECC register. |
| 21:53.57 | hno | slapin, with a static seed per page. |
| 21:54.18 | drachensun | they are pretty capable though, but one processor is almost as much as a MK802 from the cheapest sources |
| 21:54.54 | hno | slapin, disabled only when checking for erased or bad pages I think. |
| 21:56.08 | slapin | hno: can you play with it? I think we can make command to disable or enable compatibility for testing. I want to concentrate on making it work properly (partial reads). |
| 21:56.27 | hno | slapin, use of the randomizer is optional, but increases NAND lifetime and reliability. |
| 21:56.55 | hno | have you pushed your read code? |
| 21:57.03 | slapin | I will push now |
| 21:58.15 | hno | Still fighting with rhe initialization issue. But quite clueless on what it really is about. |
| 21:59.42 | slapin | hno: pushed to work branch |
| 21:59.59 | slapin | hno: it was rebased to your mtd branch |
| 22:00.34 | slapin | hno: why so little NAND controllers out there implement randomizers? |
| 22:01.23 | slapin | hno: and what mechanics for randomizer to prolong NAND lifetime if seeds are fixed? |
| 22:02.16 | hno | It reduces the chances that large areas have the same cell charge. |
| 22:05.06 | hno | if I remember right. |

| 22:33.38 | ZaEarl | that reminds me of the fun that was MacOS 8. They stored the system interrupt tablet at 0, without any memory protection. Any write to a null pointer would overwrite the system interrupt tablet. Boom. |

| 22:39.11 | slapin | hno: does u-boot's mtd struct contains buffer of page size? |
| 22:40.38 | slapin | also somebody needs to set proper page size in controller |
| 22:42.26 | hno | slapin, I seem to get the same non-random data in every page. lots of 0x30, lots of 0xff, lots of 0x00, lots of 0x30. |
| 22:42.37 | focus_it | Just noticed - cubieboard has raised $86,000 - $36,000 more than the $50,000 they were seeking. May be with some of the profit cubie should think about start making own SoC |
