| 15:42.34 | prpplague | JonHylands: whats cookin? |
| 15:42.43 | JonHylands | another simple question - just want to make sure |
| 15:42.52 | prpplague | JonHylands: okie dokie shoot |
| 15:42.55 | JonHylands | I'm doing a custom board for MicroRaptor for the Hammer |
| 15:43.00 | prpplague | ok |
| 15:43.24 | JonHylands | the only pins I need to hook up are +5 and ground, right? I'm also feeding out the two serial ports, and USB |
| 15:44.03 | prpplague | JonHylands: yea, all the hammer needs for operation is the +5v and the ground |
| 15:44.26 | prpplague | JonHylands: the +5v actually can be a range from +3.7v to +5.9V |
| 15:44.38 | JonHylands | A while back you showed me a wifi board that was SPI - what if I want to include capability for that board? |
| 15:44.49 | prpplague | JonHylands: one sec phone |
| 15:44.54 | JonHylands | do I need anything special for that other than the SPI pins? |
| 15:44.55 | JonHylands | sure |
| 15:47.21 | prpplague | JonHylands: for the SPI wifi you need clk, miso, mosi , chipselect(gpio), and an EINT |
| 15:47.37 | JonHylands | is that board going to be available any time soon? |
| 15:47.40 | prpplague | JonHylands: along with power and ground |
| 15:47.53 | prpplague | JonHylands: iirc zcomax has them available now |
| 15:48.05 | JonHylands | does the build support them? |
| 15:48.08 | prpplague | JonHylands: i've not made any tests with the hammer as of yet |
| 15:48.34 | prpplague | JonHylands: the driver is part of the 2.6.25 kernel so you've have to upgrade your kernel |
| 15:48.39 | JonHylands | ok |
| 15:49.00 | JonHylands | so basically if I have a header with those pins available, sooner or later I should be able to use it |
| 15:49.02 | prpplague | JonHylands: i have plans to make them available, both the hardware and the software in the future |

| 15:56.00 | JonHylands | They think its pretty cool |
| 15:56.16 | JonHylands | although it will be a lot cooler once I get this board done and mounted |
| 15:56.57 | prpplague | ce_geek: more gpio, sdio, complete lcd signals, battery fault control, and suspend/resume controls |
| 15:57.00 | JonHylands | I'm definitely under-utilizing the I/O capabilities, but I'll be pushing the computational limits |

| 16:01.47 | JonHylands | 50 pin connector :-( |
| 16:02.04 | prpplague | JonHylands: yea, not so easy to work with on the hobby side |
| 16:02.15 | prpplague | JonHylands: we've already started laying out a breakout board |
| 16:02.25 | JonHylands | well, I can do SMT stuff, so its not impossible |
| 16:02.44 | prpplague | JonHylands: yea, problem is the matching connector is hard to get in small qty |
| 16:02.49 | JonHylands | yeah |
| 16:03.32 | JonHylands | I think I'll skip on it for now, and just use the bluetooth module for wireless |

| 16:55.23 | prpplague | anyone gotten to work with a cortex board yet? |
| 16:55.45 | ce_geek | prpplague: Someone asked a while ago if it was possible to upgrade the memory on the hammer board. It looks as though unless there's an extra address line connected, that wouldn't work. Is my assumption accurate? |
| 16:56.14 | prpplague | ce_geek: the pcb pad for the hammer's sdram is compatible with larger sdram |
| 16:56.25 | prpplague | ce_geek: we could add up to 64mb sdram |
| 16:57.04 | ce_geek | Okay, so does that mean that there are pads for additional address lines that are currently reflected as no connection on the HAMMER_REV-B schematic? |
| 16:57.18 | prpplague | ce_geek: its just that for people coming up from pic's and avr 32mb seemed enough |
| 16:57.29 | prpplague | looks at the schematic |
| 16:58.06 | ce_geek | prpplague: That or there's another 16 data lines that have pads that are just not connected, perhaps? |
| 16:58.12 | SpeedEvil | prpplague: sure - it's plenty - for those that want to basically reuse desktop stuff - it's not quite it |
| 16:58.51 | SpeedEvil | ce_geek: I don't think 32*16M chips are common. |
| 16:59.00 | ce_geek | Probably not :) |
| 16:59.01 | prpplague | ce_geek: no to upgrade the memory the sdram chip would be replaced with a larger one |
| 16:59.35 | prpplague | SpeedEvil: i'm sorry i did not understand your statement |
| 17:00.24 | SpeedEvil | prpplague: 32M is fine if you're thinking of it of a bigger PIC or AVR. It's not really ideal if you're trying to jam random bits of originally desktop/server software that happens to do what you want onto it. |
| 17:01.00 | prpplague | SpeedEvil: well, its an embedded device, why would you shove desktop software on an embedded device? |
| 17:01.30 | ce_geek | prpplague: I'm trying to understand how a larger memory chip would increase the capacity. The schematic shows 24 address lines, enough to address 16M memory locations, each two bytes wide, for a total of 32MB. Unless there's a pad on the board for an additional address line to be connected, I'm not sure how you would be able to address 64MB. That's what I'm trying to understand. |
| 17:02.20 | ce_geek | prpplague: If there's a pad for ADDR25, a pin shown as disconnected on the schematic, then I would completely agree that a larger chip would work. |
| 17:02.30 | prpplague | ce_geek: ahh i see your misunderstanding, we have a different pcb that has the changes nessary for the larger sdram |
| 17:02.42 | ce_geek | prpplague: Ah, okay. |
| 17:03.17 | ce_geek | prpplague: So if someone walked up to me and asked if I could upgrade the memory on this board, the answer is no, because there wouldn't be a way to connect an additional address line. Is that correct? |
| 17:03.18 | prpplague | ce_geek: due to the size of the hammer, it is not practical to have different pcb pads along with configuration resistors |
| 17:03.31 | SpeedEvil | prpplague: because it does what's needed without having to write stuff. For example yes you can write a windowing system lots smaller than X, but a GUI using X and GTK may be much faster to develop. |
| 17:03.45 | prpplague | ce_geek: and that they would have to have the abilitity to do bga packages |
| 17:04.07 | prpplague | SpeedEvil: x along with gpe runs fine on 32mb |
| 17:04.26 | ce_geek | prpplague: Haha, yeah. That's always another hurdle. We do have hot air rework. I have not played myself, but someone suggested that would do the trick. |
| 17:04.50 | SpeedEvil | prpplague: I'm not saying it doesn't - but X plus other stuff gets tight. |
| 17:04.57 | prpplague | ce_geek: indeed if the pcb had the pads and lines brought out you could do a bga re-work |
| 17:05.06 | ce_geek | prpplague: So is there another revision of the hammer board that has the infrastructure required to support a 64MB chip? |
| 17:05.24 | prpplague | SpeedEvil: i must have alot different needs since i rarely need more than around 20mb for x and related applications |
| 17:05.31 | prpplague | ce_geek: correct |
| 17:05.32 | SpeedEvil | Oh - and digikey tells me that you can get 32*32M chips - but that they are DDR |
| 17:05.45 | ce_geek | prpplague: Okay, that's all clear now. Thanks! |
| 17:05.51 | prpplague | SpeedEvil: you can get 32x32mb sdram |
| 17:06.13 | prpplague | SpeedEvil: but that doesn't do you any good for the hammer, its x16 bus |
| 17:06.27 | SpeedEvil | yes - the 2410 isn't inherently though |
| 17:06.39 | ce_geek | Are you guys talking about actually running X on the hammer? |
| 17:06.41 | dijenerate | prpplague: dude! howdy |

| 17:08.02 | SpeedEvil | prpplague: yes - on rechecking it's p195 on my datasheet |
| 17:08.13 | dijenerate | prpplague: yeah that would do it |
| 17:08.17 | SpeedEvil | um_s3c2410a_rev11.pdf |
| 17:08.20 | prpplague | SpeedEvil: yea, you can use x32 and thats the prefered method |
| 17:08.26 | SpeedEvil | (of course hammer does not bring out that many pins) |
| 17:08.31 | prpplague | SpeedEvil: but that also means alot more lines brought out |
| 17:08.52 | dijenerate | prpplague: well you're busy so when you have a sec, I'd like a bit of help |
| 17:09.22 | SpeedEvil | I was simply wondering if it was possible to do a maximum bank capacity with one chip on the 2410 - not directly related to the bammer. Sorry for the confusion. |
| 17:10.50 | *** join/#edev T0mW (n=Tom@24.115.218.135.res-cmts.sth.ptd.net) |
| 17:10.51 | prpplague | dijenerate: i can't guarrantee i can i help, but you are welcome to ask |
| 17:11.03 | T0mW | heh |
| 17:11.03 | prpplague | SpeedEvil: ahh |
| 17:11.26 | dijenerate | prpplague: I got that Flipstart PC http://www.flipstartpc.com |
| 17:11.31 | prpplague | SpeedEvil: the easiest configuration to max out the size of the sdram for the 2410 is to use 4 x16 sdrams |
| 17:11.39 | prpplague | dijenerate: ahh |
| 17:11.41 | dijenerate | prpplague: Installed linux |
| 17:11.43 | prpplague | dijenerate: fun fun |
| 17:12.06 | dijenerate | prpplague: Ubuntu distro, figuring big community easy to get help |
| 17:12.13 | SpeedEvil | prpplague: In theory you could do 8 128M banks - but that'd be silly |
| 17:12.23 | prpplague | SpeedEvil: use 4 MT48LC32M16 's |
| 17:12.32 | dijenerate | prpplague: got no mouse buttons or trackstick even tho' trackpad works |
| 17:12.33 | prpplague | SpeedEvil: actually no |
| 17:12.41 | prpplague | dijenerate: you can only do 2 sdram banks |
| 17:12.50 | prpplague | dijenerate: interesting |
| 17:12.54 | SpeedEvil | misread. |
| 17:12.56 | ce_geek | Uh, wow. I guess I never really thought about running X on the hammer. How do you.... view it? What is the display device? |
| 17:13.11 | ce_geek | I could definitely see some sort of VNC server running and then connecting to that |
| 17:13.24 | prpplague | ce_geek: remember X11 was designed as a remote services application |
| 17:13.27 | SpeedEvil | ce_geek: it's possible to connect a 8 bit color display to it |
| 17:13.36 | dijenerate | prpplague: turns out the mouse buttons and trackstick are on the same usb connection as the synaptic trackpad |
| 17:13.41 | SpeedEvil | ce_geek: using the inbuilt LCD controller |
| 17:13.44 | prpplague | ce_geek: like for the nail board, i run X on the nail but view the output on my desktop |
| 17:13.54 | prpplague | ce_geek: you can also add an lcd on the hammer |
| 17:13.55 | dijenerate | prpplague: linux sees one or the other, not both |
| 17:13.57 | SpeedEvil | ce_geek: of course it's not great color, but it's quite good. |
| 17:14.13 | ce_geek | I guess that makes sense. |
| 17:14.36 | prpplague | dijenerate: interesting, i'm surprised that its not seeing both |
| 17:14.52 | ce_geek | prpplague: I've played with X quite a bit with this distributed display stuff, exporting displays and all sorts of other funkyness, just hadn't thought of it in this context I guess. |
| 17:14.55 | prpplague | dijenerate: what does the /proc/bus/usb/devices look like? it show both devices? |
| 17:15.03 | dijenerate | prpplague: second prob, that Infopane/Dinoboard I mentioned coontrols power for the WWAN module |
| 17:15.13 | dijenerate | prpplague: shows only one |
| 17:15.14 | ce_geek | So you view the output on your desktop... is the DISPLAY variable just set to your remote machine when X gets started on the hammer? |
| 17:15.21 | prpplague | dijenerate: oh fun, gonna have to dig on that one |
| 17:15.57 | prpplague | ce_geek: yea, you just ssh into the nail board, make sure that x11 forwarding is enabled, and then you can just execute commands |
| 17:16.02 | dijenerate | prpplague: Dinoboard is a freescale MX-1 based box on the system's USB bus |
| 17:16.39 | prpplague | ce_geek: i.e. if you execute the command, xterm , on the nail after ssh'n in, an xterm window will open on your desktop, but it will be for the nail board, not your desktop |
| 17:16.39 | dijenerate | prpplague: can wake the system out of standby and synch with Outlook in windows |
| 17:17.18 | ce_geek | prpplague: I can see how that would work for individual applications. With the LCD, are you actually running an X desktop? |
| 17:17.29 | dijenerate | prpplague: found jtag, so since vulcan has no docs on its O.S. I'm thinking a custom linux is in order |
| 17:17.33 | prpplague | dijenerate: if it were me i'd hot wire the wwan module power control so i could do wwan testing without using the dinoboard |
| 17:17.53 | prpplague | ce_geek: yea, you can run something like matchbox |
| 17:18.00 | prpplague | ce_geek: with applications like gpe |
| 17:18.11 | ce_geek | Damn that |
| 17:18.13 | ce_geek | That's cool |
| 17:18.27 | dijenerate | prpplague: I was actually thinking of replacing the dinoboard with something else |
| 17:18.29 | prpplague | dijenerate: thats gonna be pretty time consuming but its doable |
| 17:18.35 | prpplague | dijenerate: oh? |
| 17:18.41 | prpplague | dijenerate: thats doable too |
| 17:19.14 | dijenerate | prpplague: it's technically an arm pda permanently tethered to the system's USB |
| 17:19.30 | prpplague | dijenerate: yea |
| 17:19.48 | prpplague | dijenerate: problem is going to be replacing it with something small enough |
| 17:20.30 | prpplague | dijenerate: its totally doable to replace it with linux, it's just matter of how much time it will take and how much information the OEM shares |
| 17:21.23 | prpplague | dijenerate: i rarely hack devices that cost more than $100 , mainly because i usually require 3 devices to really do a hard core quick hack |
| 17:22.38 | T0mW | yeah, one to destroy, one to develop on, then one for "just in case I break the second one". |
| 17:22.53 | dijenerate | prpplague: the OEM has nothing to share, I've tried and the Dinoboard looks sorta like this but with an extended board for the Mini-PCI-e slot http://www.personal-media.co.jp/pictures/tearm920mx1.jpg |
| 17:23.06 | prpplague | looks |
| 17:23.43 | prpplague | dijenerate: well the first thing to do is get a wiki page going, get a complete chiplist and locate matching datasheets |
| 17:23.52 | dijenerate | prpplague: pretty standard ref board, they haven't done much with it just different placement of buttons |
| 17:24.29 | prpplague | dijenerate: so you've done a chip list comparison? |
| 17:24.40 | dijenerate | prpplague: one prob, they soldered the RF shield to the board, so can't see the chip labels |
| 17:24.54 | prpplague | hands dijenerate a large soldering iron |
| 17:25.24 | dijenerate | prpplague: as much as I could using https://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=772007&native_or_pdf=pdf |
| 17:25.50 | prpplague | looks |
| 17:26.27 | dijenerate | prpplague: page 14 |
| 17:27.09 | dijenerate | prpplague: I've also managed to establish a serial USB comm with it in linux only reponse was when I echoed 'AT' to it and all it did was shutdown 'til next PC reboot |
| 17:30.01 | prpplague | dijenerate: interesting it looks to just have some flash, no sdram |
| 17:30.15 | prpplague | dijenerate: well i guess it could be the other way around, could be just sdram |
| 17:30.20 | prpplague | dijenerate: which makes more sense |
| 17:30.37 | prpplague | dijenerate: i'm wondering if the firmware isn't uploaded with the usb connection is enumerated |
| 17:31.11 | dijenerate | prpplague: basically it's empty without the windows tools.... nice |
| 17:31.33 | ce_geek | prpplague: I was looking at the programmer's model for the 2410. It says that in the THUMB state it executes 16-bit halfword-aligned thumb instructions. Does that mean the 2410 on the hammer board is running in thumb mode, since the data bus is 16 bits wide? |
| 17:32.01 | dijenerate | prpplague: because under linux it simply shows the 'Welcome to Infopane' splash screen |
| 17:33.05 | prpplague | ce_geek: no, the 2410 along with its relatives have the capability of using different bus widths for flash and sdram, for instance on the hammer, the 2410 makes two reads of 16 inorder to populate the 2410's internal registers |
| 17:33.10 | dijenerate | prpplague: there are also some dlls in windows that seem to carry bits of its menu... |
| 17:33.23 | prpplague | ce_geek: where as with 32 bit bus you just make one read |
| 17:33.29 | ce_geek | prpplague: Okay, slick. Thanks. |
| 17:33.39 | adyer | prpplague: could be stacked package ram + flash |
| 17:33.40 | prpplague | ce_geek: its a trade off, 16 bit you don't have to run as many lines, but you double the number of reads required |
| 17:33.51 | prpplague | adyer: i doubt that |
| 17:34.10 | dijenerate | adyer: cost |
| 17:34.18 | prpplague | dijenerate: yea, it looks like it might have a small eeprom |
| 17:35.32 | dijenerate | prpplague: so it awaits chatter from the main O.S. and that's it, other than that it's dumb |
| 17:36.07 | dijenerate | prplague, go any experience with disassembly of winbloze dlls? |
| 17:36.10 | prpplague | dijenerate: yea looks to be just enough to init the system and wait for an upload |
| 17:36.16 | adyer | i.MX wont boot over USB or from eeprom |
| 17:36.25 | prpplague | dijenerate: remember this is just a guess based on what we are looking at in the picks |
| 17:36.40 | prpplague | adyer: you sure of that? |
| 17:36.45 | adyer | i.MX has serial or nor flash (cant remember about nand) |
| 17:36.53 | dijenerate | prpplague: I know, but it makes sense given what else I've seen |
| 17:37.02 | adyer | we use i.MXL for stuff |
| 17:37.18 | prpplague | adyer: ahh, |
| 17:37.44 | prpplague | adyer: what method of serial boot does it require? i.e. does it have an AT command interface? |
| 17:38.08 | adyer | prpplague: no, it has a weird loader prog IIRC |
| 17:38.14 | prpplague | ahh |
| 17:38.24 | prpplague | wonders about a serial eeprom then |
| 17:39.06 | adyer | .me looking for ref manual |
| 17:39.06 | dijenerate | you guys sure it's the same CPU/Chipset in the (blurred) photo in the pdf? |
| 17:40.14 | prpplague | dijenerate: not sure |
| 17:40.23 | prpplague | dijenerate: thats marked as MX-1 |
| 17:40.33 | prpplague | adyer: that the same as what you are refering to? |
| 17:40.39 | adyer | dijenerate: it's an mx-1 which is really close to the mxl we use |
| 17:41.53 | prpplague | dijenerate: really need to get a detailed chiplist |
| 17:42.13 | dijenerate | I'll desolder and check it |
| 17:42.54 | dijenerate | but if it is MX-1, from experience, how flexible is it, and how well documented? |
| 17:43.50 | adyer | dijenerate: docs are okay and available - it's similar to the samsung arm9 stuff. linux support is not as good |
| 17:44.12 | prpplague | looks like the MX1 has 128k of internal sram |
| 17:44.19 | dijenerate | damn, I was hoping you would say that |
| 17:45.12 | dijenerate | I really would prefer linux or a RAM based system |
| 17:45.29 | adyer | http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX1&nodeId=0162468rH311432973ZrDR&fpsp=1&tab=Documentation_Tab |
| 17:48.07 | dijenerate | oh... the reading again |
| 17:48.09 | dijenerate | lol |
| 17:48.15 | dijenerate | better get started |
| 17:48.55 | dijenerate | adyer: your comment about linux support... do you mean interface wise or running linux on it |
| 17:50.08 | prpplague | dijenerate: running linux |
| 17:50.24 | prpplague | dijenerate: its just not was well maintaned by the OSS community |
| 17:50.38 | adyer | dijenerate: driver support, 2.6.x kernel support is poor. Still a lot of non-platform drivers, no official freescale tree |
| 17:51.36 | adyer | dijenerate: general aanswer from freescale is talk to microcross, and they want 40k$ for everything :-( |
| 17:51.56 | dijenerate | the i.MX stuff is pretty flexible tho' would you say? |
| 17:51.59 | adyer | dijenerate: we said f&(*&(* that, but our code isn;t the best |
| 17:52.41 | adyer | dijenerate: yes, it's okay, has LCD , USB slave, timers, SPI, I2C, external bus ID, SDRAM control, etc |
| 17:53.47 | dijenerate | I mean, could I write something that synchs with thunderbird, (like it does with outlook out of the box from vulcan), plays mp3s off my HDD, basic multimedia stuff like that |
| 17:54.31 | dijenerate | my question is, how much Ram does this thing have if it synchs with outlook? |
| 17:54.33 | adyer | dijenerate: yes, we have alsa working with a wolfson codec (again not in tree) |
| 17:54.49 | adyer | dijenerate: our board has 64M SDRAM :-) |
| 17:54.56 | dijenerate | ok |
| 17:56.03 | prpplague | dijenerate: if the dino board comes up and displays some text even when its running linux on the main system, i suspect that its getting startup code from somewhere other than via the main system |
| 17:56.29 | prpplague | dijenerate: my guess is that it has flash onboard and probably uses the internal 128k sram |
| 17:56.40 | prpplague | dijenerate: 128k would be enough for a small system |
| 17:56.53 | prpplague | dijenerate: didn't you say it was a proprietary OS running on it? |
| 17:57.07 | dijenerate | well it displays what looks like a boot splash |
| 17:57.20 | dijenerate | does it in windows too, during boot |
| 17:57.54 | dijenerate | Vulcan's logo and 'welcome to infopane' in colour |
| 17:58.06 | prpplague | dijenerate: yea, thats gotta come from some storage place |
| 17:58.19 | dijenerate | so maybe just a boot splash |
| 17:58.39 | dijenerate | I figured it must have some init stuff on it |
| 17:58.42 | prpplague | dijenerate: really can't do alot till you got a complete chiplist so you can determine if that chip along side the MX1 is flash or sdram |
| 17:59.09 | dijenerate | ok, I'll get on that this afternoon |
| 17:59.50 | dijenerate | btw thanks for the help you guys |
| 18:01.53 | adyer | dijenerate: just pulled the i.mx1 ref manual and for sure it supports only booting from serial port, sync flash (don't ask), or the external parallel bus (nor flash) |
| 18:03.41 | prpplague | adyer: yea just looking at those options |
| 18:03.57 | prpplague | dijenerate: if you've got jtag up, you can get the value for the boot config |
| 18:06.27 | adyer | lol, just pulled down openocd - its up to rev. 522 (busy guys!). Last I pulled was 144 :-) |

| 18:25.35 | dijenerate | prpplague: 1 word... Virtualization |
| 18:25.57 | prpplague | dijenerate: i'm just as happy with 32mb |
| 18:29.10 | dijenerate | prpplague: if you have a set of I/O buttons on your main system's hardware, how difficult is it to control the MX-1s menu with them when the main PC is in standby |
| 18:29.52 | dijenerate | prpplague, given the MX-1 machine is connected as a USB peripheral via serial USB connections |
| 18:31.24 | SpeedEvil | dj: essentially impossible - the PC needs to wake to use USB |
| 18:31.33 | dijenerate | the main system's jog dial and another peripheral button register an event in linux but in windows they control the MX-1's menu |
| 18:31.52 | SpeedEvil | If I understand what you're saying. |
| 18:31.52 | dijenerate | SpeedEvil: this Bios allows it |
| 18:32.17 | SpeedEvil | dijenerate: do you mean simply that it wakes on keypress? |
| 18:32.20 | prpplague | dijenerate: pretty difficult |
| 18:32.27 | SpeedEvil | dijenerate: because that's not really the same at all |
| 18:32.36 | dijenerate | not the main pc, just the Infopane |
| 18:33.00 | prpplague | dijenerate: if the mainpc is suspended |
| 18:33.33 | dijenerate | when you hit these keys, the main pc remains suspended but they control the MX-1 based PCs menu |
| 18:34.52 | dijenerate | all this makes me wonder exactly how this MX-1 works and how much of its OS is in its eprom and how much is in the main PC's RAM |
| 18:35.21 | SpeedEvil | dijenerate: look at the provided circuit diagrams and firmware dissasembly :/ |
| 18:35.43 | dijenerate | for the MX-1? |
| 18:36.02 | dijenerate | cause Vulcan has given nothing on their Flipstart |
| 18:39.04 | SpeedEvil | I know - I was commenting on the annoying lack of openness in general. |
| 18:39.21 | SpeedEvil | Well - I assumed |
| 18:40.38 | SpeedEvil | Probably the most sane way would be to sniff the bus. |
| 18:40.43 | SpeedEvil | And pull off the commands. |
| 18:44.04 | dijenerate | well was doing an API sniff, but it just reminded me why I hate .NET |
| 18:44.12 | SpeedEvil | :/ |
| 18:44.52 | dijenerate | the whole world should be GPL'd |
| 18:45.25 | dijenerate | and .NET should be banned.... along withe the rest of Microsoft's crud |
| 18:49.46 | ds2 | Windows should be classified as a WMD! |
| 18:52.31 | dijenerate | lol |
| 18:54.19 | adyer | if I was trying to make a PC & phone combo, I would make the i.MX handle the buttons, outside display, and power management (probably reusing an exisiting design). |

| 21:28.45 | dijenerate | prpplague: tried something with that Dinoboard a few minutes ago... |
| 21:29.35 | dijenerate | prpplague: I moved the folder with the dll files I mentioned before (the ones that seemed to contain stuff resembling the menus) |
| 21:30.07 | dijenerate | prpplague: so windows couldn't see it and the app couldn't run... |
| 21:30.36 | dijenerate | prpplague: then I shutdown the PC and removed the battery and power |
| 21:31.04 | dijenerate | prpplague: when I booted windows again, I got nothing but the splash screen |
| 21:31.32 | dijenerate | prpplague: seems the menus come from windows at boot, sent over USB |
| 21:31.51 | dijenerate | prpplague: the eprom doesn't have much in it |
| 21:38.30 | dijenerate | and.... great no one's home.... I'm doing the monologue again... |

| 21:44.57 | prpplague | dijenerate: yea, i didn't figure the flash(where ever it is stored) had much other than enough to bring up the system |
| 21:45.12 | prpplague | dijenerate: probably works like a remote menu system |
| 21:45.27 | prpplague | dijenerate: i.e. something like the lcd's on usb voip devices |
