| 14:32.50 | g1powermac_PB | just found and ripped apart an old vonage router/voip box |
| 14:33.24 | g1powermac_PB | its got this chip as its main proc: http://focus.ti.com/general/docs/bcg/bcgprodcontent.tsp?contentId=4027&navigationId=11909&templateId=6116 |
| 14:35.10 | prpplague | interesting chip |
| 14:35.13 | g1powermac_PB | the board has a really obvious unpopulated 14 pin header. . .wonder if thats the jtag on this sucker |
| 14:35.43 | prpplague | probably |
| 14:36.25 | prpplague | g1powermac_PB: speaking of jtag, zipitwireless folks make any comments on the discovery of uart and jtag |
| 14:36.28 | prpplague | g1powermac_PB: ? |
| 14:36.31 | g1powermac_PB | the weird part of the board is that on the underside is a copper panel soldered on |
| 14:36.43 | g1powermac_PB | right over components |
| 14:36.51 | g1powermac_PB | nope, notta one |
| 14:37.17 | prpplague | interesting |
| 14:37.28 | g1powermac_PB | yea |
| 14:37.44 | g1powermac_PB | its weird, either the guy didn't see me mention it, or they don't want to comment |
| 14:37.45 | prpplague | g1powermac_PB: i get the feeling that they aren't selling like they expected |
| 14:37.54 | g1powermac_PB | possibly |
| 14:38.05 | prpplague | g1powermac_PB: has anyone else discussed in on #zipit? |
| 14:38.26 | g1powermac_PB | nope, its been really quiet there |
| 14:38.52 | prpplague | checks the lgos |
| 14:40.26 | prpplague | g1powermac_PB: yea pretty quiet |
| 14:40.50 | prpplague | g1powermac_PB: rumor has it that the folks selling the z2 on ebay are the zipitwireless folks |
| 14:40.52 | g1powermac_PB | needs to spur some interest back into the zipit |
| 14:41.02 | g1powermac_PB | oh, might be |
| 14:41.13 | g1powermac_PB | though prolly not the one I bought from |
| 14:41.40 | g1powermac_PB | ok, that header has got to be jtag |
| 14:41.50 | g1powermac_PB | heh, this would be an interesting board to hack |
| 14:42.12 | g1powermac_PB | should stay focused on the zipit. . . .dang attention issues ;-) |
| 14:43.18 | prpplague | g1powermac_PB: just a note, mips jtag headers don't always match arm |
| 14:43.28 | prpplague | g1powermac_PB: be sure and check the pinouts on the elinux jtag page |
| 14:43.29 | g1powermac_PB | ahh |
| 14:44.04 | g1powermac_PB | checked the pinout of the chip and followed the traces coming off the header, it goes right to the jtag area |

| 15:11.00 | CosmicPenguin | I think he shares my opinion that kernel development isn't for everybody, and that may make him elitist (as I am) |
| 15:11.18 | CosmicPenguin | But thats not always a bad thing for a kernel maintainer |
| 15:11.33 | dfarnsworth | oh, I'm still at MV. I'm don't even recognize TS. :) |

| 15:23.21 | prpplague | CosmicPenguin: what kind of analog devices did you have in mind? |
| 15:24.58 | chouimat|work | prpplague: a nice small add on board for the hammer would be a CAN interface :) |
| 15:27.23 | prpplague | chouimat|work: what would you use it with? |
| 15:27.39 | prpplague | chouimat|work: i know the basics for CAN, but not sure what most people use it with |
| 15:28.53 | chouimat|work | prpplague: probably a small CAN to jabber gateway ... the one I made is too big for deployment (if I ever decide to deploy it) |
| 15:29.13 | prpplague | chouimat|work: CAN to jabber? |
| 15:29.59 | prpplague | chouimat|work: what kind of CAN device would have connected to ti? |
| 15:33.38 | chouimat|work | prpplague: I was just writing the code ... the paranoid nutcase never told me what he wanted to do with it ... thanks now I own all the code I wrote for him for 7 years ... I currently have no use for the stuff, but I know some people might have and since the hammer is more powerful than the lcp2148 + other arm9 cpu combo I was using ... anyway it was just an idea and I hate to see this code going to waste but I don't think I will ever touch it |
| 15:33.38 | chouimat|work | again ... |

| 15:40.23 | SpeedEvil | chouimat: $150 or so in parts for the ECU and maybe $50 for the sensors if you can't use the existing. |
| 15:40.29 | SpeedEvil | (if you DIY) |
| 15:40.43 | chouimat|work | no bad |
| 15:41.18 | SpeedEvil | If I was in government, I'd mandate one ECU standard for all vehicles. |

| 18:36.10 | g1powermac | hahah |
| 18:36.13 | agaffney | mmm |
| 18:54.30 | GPSFan | g1powermac: I've been pokeing at blob, and come to the conlusion that the reblob command does what it's supposed to, as far as jumping to the downloaded code. the new code begins to execute (I've had to modify start.S to print out some stuff when it gets there) but it looks like the stack is hosed. I can call a subroutine (bl subroutine) and it gets there, but doesn't return properly. |
| 18:54.56 | g1powermac | interesting |
| 18:55.39 | GPSFan | I keep thinking about setting up jtag and see if I can single step/breakpoint through the code. |
| 18:55.41 | ds2 | doesn't the ARM lack a hardware stack? |
| 18:56.11 | roxfan2 | it has one, but subroutine calls don't use it |
| 18:56.18 | GPSFan | ds2: it has a dedicated stack pointer register. |
| 18:56.20 | roxfan2 | they use link register |
| 18:56.35 | prpplague | GPSFan: really should start looking at porting apex that dealing with blob |
| 18:56.36 | GPSFan | hence the bl (branch & link inst. |
| 18:57.28 | ds2 | GPSFan: hmmmm R13? thought that is managed by software and there is only a 1 level link register? |
| 18:58.16 | GPSFan | prpplague: that would sure be nice, blob is so full of it, the screen is turning brown ;>) |
| 18:58.21 | GPSFan | ds2: R14 |
| 18:58.28 | prpplague | GPSFan: hehe indeed |
| 18:58.47 | prpplague | GPSFan: blob has no future, might as well move forward |
| 18:58.52 | ds2 | so there is no real "stack" beyond the 'lr', right? |
| 18:59.15 | roxfan2 | no, there isn't |
| 19:00.54 | GPSFan | prpplague: there is evidence that someone had problems with blob startup since there is a leftover file startup.S.memcpy which has a bunch of print's and comments like: "Didn't make is this far so comment out this out" |
| 19:01.17 | prpplague | hehe |
| 19:02.26 | GPSFan | it's in the aeronix patch so it must have been them. |

| 19:04.02 | ds2 | what's a top2048? |
| 19:04.09 | g1powermac | a universal programmer |
| 19:04.38 | GPSFan | ds2: could be lots of things. I remember using reblob years ago on the tuxscreen, and it working to the point of giveing the blob prompt. that must have been 2.0.3 or later.. |
| 19:05.03 | ds2 | does it do GAL22V10's? And you got a taker for a Xeltek programmer? ;) |
| 19:05.17 | g1powermac | think it does GALS |
| 19:05.19 | prpplague | usually at that stage you have to look at either a linking address problem or the sdram was not properly initialized |
| 19:05.34 | g1powermac | ds2, this is what it does: http://www.top2048.com/gb/DeviceList/top2048.txt |
| 19:05.41 | GPSFan | prpplague: can apex run out oo RAM? |
| 19:06.06 | prpplague | a long time problem with the linking scripts for blob was that make didn't always catch it when you add new lines such as debugging printf's which cased the address the be incorrect |
| 19:06.10 | prpplague | GPSFan: yea |
| 19:06.28 | ds2 | not that much better then the xeltek :/ |
| 19:06.37 | GPSFan | prpplague: at this point the sdram is set up by the initial blob. |
| 19:06.55 | prpplague | GPSFan: hehe, it should be |
| 19:07.05 | prpplague | GPSFan: doesn't mean something didn't get overwritten |
| 19:08.21 | GPSFan | prpplague: can apex "reapex" a test instance of iteslf? like the reblob? |
| 19:08.30 | prpplague | GPSFan: yep |
| 19:09.04 | GPSFan | knew it could I just wanted prpplague to say it ;>) |
| 19:09.16 | prpplague | hehe |
| 19:09.35 | prpplague | GPSFan: i used do lots blob dev |
| 19:09.41 | prpplague | GPSFan: but it got to be such a mess |
| 19:10.20 | GPSFan | prpplague: last I did was messing with the tuxscreen memory timings. |
| 19:10.47 | g1powermac | is there any programmer out there that actually works with linux? |
| 19:10.48 | prpplague | i had it running on the webpal and also on the omap dev platform |
| 19:11.05 | prpplague | g1powermac: i assume you mean eprom programmer |
| 19:11.07 | GPSFan | prpplague: so what would be the level of effort to get apex onto the pxa270/z2 platform? |
| 19:11.18 | g1powermac | prpplague, universal programmer actually |
| 19:11.22 | prpplague | GPSFan: pretty minimal |
| 19:11.27 | prpplague | g1powermac: no such animal |
| 19:11.33 | prpplague | g1powermac: people just claim that |
| 19:11.41 | g1powermac | k |
| 19:11.51 | g1powermac | alright, I'm gone for a couple of hours |
| 19:11.52 | g1powermac | bbl |
| 19:11.59 | prpplague | g1powermac: there are a wide number of linux support device programmers |
| 19:12.25 | prpplague | GPSFan: basically need a few header files with register locations and values |
| 19:12.36 | prpplague | GPSFan: along with a basic timer config |
| 19:12.45 | GPSFan | the reg stuff can be cut out of the blob code. |
| 19:12.46 | prpplague | GPSFan: some init sequence, and your done |
| 19:12.51 | prpplague | GPSFan: exactly |
| 19:12.58 | prpplague | GPSFan: or even the kernel would be better |
| 19:13.52 | GPSFan | prpplague: what I'd want to do is be able to load apex to ram and then "go 0xapexstart" |
| 19:14.40 | prpplague | GPSFan: yea, totally doable |
| 19:15.05 | prpplague | GPSFan: however usually the most difficult part of getting a bootloader working is the transition from flash to sdram |
| 19:16.00 | GPSFan | yeah, first stage sets up the sdram and minimal reg's, copies the second stage to ram and jumps to it. |
| 19:16.01 | prpplague | ~seen landley |
| 19:16.02 | purl | landley <n=landley@rrcs-71-42-139-208.sw.biz.rr.com> was last seen on IRC in channel #edev, 8d 18h 47m 32s ago, saying: 'Then again, my reason for attempting to upgrade to 4.2 was to try to fix m68k, and when I got far enough to prove it didn't, I lost interest...'. |
| 19:16.40 | prpplague | GPSFan: i think pxa27x support would be a nice addition to apex |
| 19:19.10 | GPSFan | prpplague: openezx folks were talking ablut an apex port in 2006. |
| 19:19.24 | prpplague | hehe |
| 19:19.29 | prpplague | GPSFan: that was mainly me talking |
| 19:19.31 | prpplague | GPSFan: iirc |
| 19:19.52 | GPSFan | prpplague: and [g2] http://ibot.rikers.org/%23openezx/20061123.html.gz |
| 19:19.58 | prpplague | looks |
| 19:20.58 | prpplague | GPSFan: yea, iirc laforge got all nasty about it |
| 19:21.12 | prpplague | GPSFan: didn't want to hear about using anything other than u-boot |
| 19:21.39 | GPSFan | prpplague: haven't read taht far, they never got reblob working either. |
| 19:22.00 | prpplague | GPSFan: and he basically bullied every one HTC and openmoko about the same |
| 19:22.11 | prpplague | everyone in |
| 19:23.06 | GPSFan | prpplague: well I'd like to see that port working just to have it working on another platform. |
| 19:23.15 | prpplague | yea |
| 19:23.30 | GPSFan | wanders off to re-read the apex website |
| 19:23.50 | prpplague | GPSFan: you can look at my addition of the s3c2410 |
| 19:23.58 | prpplague | GPSFan: its pretty clean and straight forward |
| 19:24.04 | GPSFan | k |
| 19:26.07 | prpplague | just had a quick look, probably could get it done in a day or two |
| 19:26.20 | prpplague | GPSFan: you got the url for the blob and patches for zipit? |
| 19:28.09 | GPSFan | prpplague: 2 patches: http://linux.zipitwireless.com/projects/z2kernel/browser/trunk/blob-2.0.5-pre2_to_zipit2-1.0.patch and http://linux.zipitwireless.com/projects/z2kernel/browser/trunk/blob-xscale_to_zipit2-1.0.patch |
| 19:28.24 | prpplague | GPSFan: ahh thanks |
| 19:28.40 | GPSFan | prpplague: wait tthay might not be right... |
| 19:28.58 | *** join/#edev ico2 (n=ico2@modem-1540.chameleon.dialup.pol.co.uk) |
| 19:30.31 | GPSFan | prpplague: yeah that's what I have in my tree. I'm sure you can figure out how they apply. |
| 19:30.40 | prpplague | GPSFan: yea looking now |
| 19:32.52 | GPSFan | prpplague: so in apex all the processor unique code is located in /apex/src/mach-yournewproc |
| 19:33.46 | GPSFan | prpplague: or is there platform specific stuff there too.. |
| 19:34.04 | prpplague | GPSFan: that is correct, all in your mach dir |
| 19:34.07 | GPSFan | processor = pxa270 platform = Z2 |
| 19:34.47 | GPSFan | so to add another platform one would just add stuff to /mach-xxxx |
| 19:36.41 | prpplague | GPSFan: yep |
| 19:36.59 | prpplague | GPSFan: the system already has some xscale support with the ixp stuff |
| 19:37.23 | prpplague | GPSFan: not sure if you'd want to do a mach-pxa27x or just mach-pxa |
| 19:37.54 | prpplague | GPSFan: hmm, i think pxa-27x would be better |
| 19:37.55 | GPSFan | probably mach-pxa, as there are several varients |
| 19:38.02 | GPSFan | yeah 27x |
| 19:38.30 | prpplague | GPSFan: are all of the pxa mach's in the kernel under a single dir? |
| 19:38.58 | prpplague | GPSFan: looks so |
| 19:39.52 | prpplague | GPSFan: yea, looking at the kernel i think mach-pxa would be best |
| 19:40.23 | GPSFan | yeah, 25x, 27x, sharp |
| 19:41.40 | prpplague | GPSFan: ok, so looks like you probably could use the headers from the kernel or blob |
| 19:41.52 | prpplague | GPSFan: but i bet the kernel would be better in the long run |
| 19:42.35 | prpplague | GPSFan: pxa-regs.h |
| 19:42.40 | GPSFan | using the kernel headers would be "ther right thing to do" since blob ..... well you know... |
| 19:43.15 | GPSFan | just need to make sure all the stuff is there. |
| 19:44.02 | GPSFan | prpplague: does AML have any product based on pxa? |
| 19:44.44 | prpplague | GPSFan: no, we were doing prototypes when intel sold their stuff to marvell |
| 19:45.19 | prpplague | GPSFan: once marvell got the xscale stuff they made it pretty clear very quickly they were interested in doing business with small time people that buy less than 50k units |
| 19:45.43 | prpplague | GPSFan: kind of why you are seeing a spike in designs using the s3c24xx |
| 19:46.57 | GPSFan | prpplague: yeah I figured as much. |
| 19:48.24 | GPSFan | there are lots of aeronix comments in the .def files here: blob/src/blob/xlli/mainstone/ |
| 19:48.36 | prpplague | GPSFan: yea looking, most of what you are going to have to do is mainly making sure that what you pull from the kernel get synced with the apex code |

| 21:58.49 | *** mode/#edev [+o CosmicPenguin] by ChanServ |
| 22:00.24 | g1powermac_PB | though from the looks on the silkscreening and this very weird looking unpopulated area, I would suspect that an add on card was made for it |
| 22:02.06 | g1powermac_PB | there's also one LED that isn't populated, good spot for the wifi network indicator |
| 22:03.19 | g1powermac_PB | huh, no there's two that are unpopulated |
| 22:03.34 | MonMotha | most router box thingies just use a mini-pci or similar wifi card |
| 22:03.45 | g1powermac_PB | yea, this thing could have one more phone jack attached to it |
| 22:05.34 | g1powermac_PB | MonMotha: only thing with mini-pci is that it shouldn't have an area marked as antenna on the main pcb, I would figure |
| 22:05.50 | g1powermac_PB | the mini-pci card should have all the wireless stuff on it |
| 22:06.08 | MonMotha | they sometimes route the RF through the main PCB |
| 22:06.22 | MonMotha | so there would be a flylead down from the card to the PCB, then the main PCB would have an external antenna connector |
| 22:06.39 | g1powermac_PB | hmm, interesting |
| 22:07.12 | g1powermac_PB | what would an unpopulated mini-pci pad area look like? |

| 22:11.11 | g1powermac_PB | hmm, from the pics, its definitely plausible |
| 22:12.09 | g1powermac_PB | very weird pcb |
| 22:12.42 | g1powermac_PB | still doesn't understand the copper foil soldered to part of the underside of the pcb and labeled as a ground plane |
| 22:13.04 | MonMotha | EMC? |
| 22:13.20 | g1powermac_PB | maybe |
| 22:13.23 | MonMotha | or possibly for controlled impedance purposes |
| 22:13.41 | g1powermac_PB | but why copper foil and not done in the pcb? |
| 22:14.05 | MonMotha | well, if it's EMC, they may have already committed to a design by the time the EMC reports came back |
| 22:14.05 | *** join/#edev MothaWork (n=monmotha@66.208.186.250) |
| 22:14.19 | MonMotha | at which point it may have been cheaper to just put the foil on it rather than rev. the PCB |
| 22:14.50 | g1powermac_PB | well, that would only hold if they didn't put specialized pads on the pcb for the foil |
| 22:15.14 | MonMotha | then I couldn't tell you without seeing it |
| 22:15.29 | g1powermac_PB | and they actually have it marked as ground planes on the silkscreening |
| 22:15.51 | g1powermac_PB | each corner has something like GND_P2, but each with a different number |
| 22:17.39 | g1powermac_PB | its also marked as a revision C board. . . |
| 22:17.50 | g1powermac_PB | I gotta take some shots of this thing |
| 22:18.21 | MonMotha | rev C doesn't mean it's perfect |
| 22:18.36 | MonMotha | just means they rev'd it at least twice after the initial design (which may have been a proof of concept!) |
| 22:19.02 | MonMotha | it's not uncommon to ship boards with known issues |
| 22:19.30 | MonMotha | business pressures will dictate that it get shipped "now", so things just get documented rather than fixed |
