04:12.08Russhey CosmicPenguin
04:12.25Russsorry, I've been really busy lately, hopefully I'll have work soon though, I have some leads
04:13.10CosmicPenguinRuss: I hope so
04:13.46CosmicPenguinWas that your name I saw on the cs89x0 NIC driver?
04:14.18RussI've done some work on it, I'm not sure that any of it made it into the main kernel
04:14.44RussI had to get it working with more than one chip at boot, and I also added "MII emulation"
04:15.39CosmicPenguinRuss: I have a client that is having a random interrupt overwrite its stack and he suspects that the cs89x0 might be to blame
04:16.26CosmicPenguinRuss: of course, to make things even better - its an Xscale which means really bad error messages, and no kernel debugger until we hack it in
04:16.41CosmicPenguinAnd I have to do all this across e-mail... :(
04:17.35Russok, how does he know his stack is being overwritten?
04:17.56CosmicPenguinIt looks like the return from interrupt is going to never never land
04:18.30Russwhat interrupt
04:18.36CosmicPenguin??
04:18.46CosmicPenguinAll he gets is an ABT_32 error
04:19.10CosmicPenguinOr rather:  Bad mode in data abort handler detected: mode ABT_32
04:20.03Russok, so the kernel is running, and he just gets that
04:21.36CosmicPenguinYeah
04:22.37CosmicPenguinAnd I'm 60% sure its an interrupt because the crash happens in different places when the code is changed
04:22.52CosmicPenguinAnyway, I was hoping that you would say "Oh, yeah - I know all about that"
04:23.04CosmicPenguinBut thats OK - once we get the  debugger up, we'll be better off
04:23.09Russare you sure its not just a cache coherency or sdram timing problem?
04:23.15CosmicPenguinMaybe
04:23.20Russif its either of those, a debugger will just run you in cirles
04:23.50CosmicPenguinIt is an Xscale - not the most reliable silicon on the planet
04:24.04Russif you don't load the cs89x0 module, does the problem occur
04:24.20Russor not that far yet
04:24.30CosmicPenguinRuss: I don't think so - but who knows?
04:24.43Russin my opinon, there shouldn't really be a problem you need a kernel debugger to solve
04:25.13CosmicPenguinRuss: thats a good point
04:25.32CosmicPenguinWell, I'll sit down and think about it tommorrow
04:25.39CosmicPenguinRuss: thanks for your help
04:25.55Russits pretty simple stuff, there is no smp, and if the kernel isn't too far gone, you can always request a sysrq dump via sera

15:31.05GPSFanmorning all,
15:31.19prpplagueGPSFan: morning
15:33.20GPSFananyone know how to use objdump to dump a ROM image? I've tried various option combinations, but it keeps saying that there are no symbols, which is true.
15:33.42filehi prpplague
15:33.51prpplaguefile: lo
15:39.27fileprpplague: What's up?
15:44.53CosmicPenguinhttp://www.revolution-os.com/store1.html
15:45.51CosmicPenguinGPSFan: do you want an SRec image?
15:46.47CosmicPenguinGPSFan: you want objcopy
15:49.55prpplaguefile: ssdd
15:50.54sorphinprpplague: lo POS bitch
15:51.07prpplaguesorphin: lo wcom lackey
15:51.35GPSFanCosmicPenguin: I'm trying to make sense of the dct5000 boot rom, it's raw machine code and I want to generate assy menumonics> I know there will be areas that are data and not code, but I figure I can sort those out later.
15:52.41CosmicPenguinAhh - I see - so you're not copying an ELF -> an ROm
15:52.48CosmicPenguinThats what I thought you were trying to do
15:52.51sorphinnope
15:53.10CosmicPenguinobdump --disassemble didn't work?
15:55.08GPSFanCosmicPenguin: tried that and it complained about no symbols, that was the first option I tried. I was puzzled, still am, so yesterday I went skiing instead of hacking. ;>)
15:56.55CosmicPenguinGPSFan: how was the snow?
15:58.15GPSFanCosmicPenguin: went to Powderhorn, it was a bit icy at first, but after the sun came out for a bit it wasn't bad at all. no rocks, almost corn snow. had a good time.
15:59.45GPSFanCosmicPenguin: to disassemble i used objdump -d --target=binary --architecture=mips:5000 dct5000.rom
16:01.32CosmicPenguinGPSFan: what does objdump -i give you?
16:04.40GPSFanCosmicPenguin: I'm using a cross mips tool from scanline. I am using a different machine for irc than the one I'm debugging on, so I can't past the results. but it prints out a lot of stuff having to do with elf and endian-ness. what should I be looking for in this list?
16:04.56GPSFans/past/paste
16:07.59CosmicPenguinGPSFan: apparently, thats the list of targets that obdump can recognize
16:10.55GPSFanCosmicPenguin: ok, there is a line that says binary (header endianness unknown, data endianness unknown) mips
16:11.22CosmicPenguinGPSFan: ok...
16:11.32CosmicPenguinWhats ihex?
16:12.25GPSFanthe line with ihex says the same as binary does.
16:12.38CosmicPenguinGPSFan: I was just wondering what the type wa
16:12.40CosmicPenguins
16:13.11GPSFanno idea.. :)
16:13.18CosmicPenguinGPSFan: I don't know what to tell you - when we used to burn ROMs we used .SREC format - but that was probably converted by the ROM burner during the process
16:13.20GPSFanintel hex?
16:13.26CosmicPenguinprolly
16:13.39CosmicPenguinHep
16:13.40CosmicPenguinYep
16:14.07CosmicPenguinibot: search google for ihex
16:14.13GPSFanCosmicPenguin:well, thanks anyway, I'll keep googling, there is bound to be something around.
16:15.00CosmicPenguinGPSFan: sorry I couldn't be of more help - sadly I don't have a rom to play with... :(
16:15.35sorphinCosmicPenguin: we can send you the image if that's what you mean
16:16.00CosmicPenguinsorphin: nah - I am sorry that I had to give up on the dct5000 in the first place....
16:16.32GPSFansorphin: I'm reluctant to post it anywhere, but e-mailing it around is fine.
16:16.51sorphinGPSFan: that's what i meant :P
16:16.59kergothhey
16:17.10sorphinGPSFan: that guy was disassembling the 2k rom i think
16:17.13sorphinkergoth: lo

16:18.39CosmicPenguinsorphin: hopefully, we should be at the end
16:19.16GPSFansorphin: what guy and what 2k rom were you refering to?
16:19.33sorphinGPSFan: uh.. the DCT 2000 :P and the url i put on the wiki
16:20.15GPSFanah, must have sacrificed those brain cells last evening after skiing, beeeer...
16:21.10CosmicPenguinDon't you hate it when you have to pay a bill, but you lost the evelope to send it in, so you have to write out a blank evelope?

19:27.54GPSFansorphin: trim the rom file down to 64k first, or you will get a giant output mostly of fffffff. ;>)
19:28.07sorphink
19:30.31GPSFansorphin: just browsing through the code it looks like sensible stuff. the addresses make sense after looking at the 5432 manual regarding the reset vector
19:30.45sorphinyeah
19:30.54sorphinwe ported monte to mips
19:31.00sorphinfor tivo stuff
19:31.03sorphintook some mips asm
19:34.23sorphinGPSFan: did you still get the no symbols error anyway?
19:36.44GPSFansorphin: yes, because there are no symbols in the rom file (I think).
19:36.53sorphinprolly aren't
19:42.55CosmicPenguinGPSFan: ahhhh
19:43.39CosmicPenguinGPSFan: anything fun?
19:43.41GPSFansorphin: section 6.3.2 in the first volume of the user manual describes where the exception vectors are. the ROM address 0 thus corresponds to physical address 0xfc00000.
19:43.55sorphinGPSFan: knew that already ;)
19:44.07sorphinfrom tivo stuff
19:44.51GPSFanso looking at the vectors at 200,280,300,380 they all jump to offset 60.
19:46.04sorphinwhat i'm wondering is if they're *anything* in the flash on there atm or just the bootrom
19:46.14GPSFanprobably data between offset 1000 and 14c8, many of the jumps low down go to 14c8
19:46.37GPSFansorphin: I bet the flash is empty.
19:48.04sorphinnod
19:50.44GPSFansorphin: since the boxes were so well closed up with those @#$%% screws, I wonder if there is a way to talk to the bootloader with gdb? spent some time this am compiling gdb for mips target, but had no luck syncing it up. Maybe GI has a similar utility that they gave out with the boxes.
19:51.13sorphini dunno
19:51.37sorphini know you can talk to the xbox remotely via the xdk
19:54.54CosmicPenguinRuss: I think you were right - using a JTAG debugger - the first time my client reads a given buffer, it works fine, the next time he reads it, he gets an data error until he reboots
19:55.01CosmicPenguinRuss: that to me is one borked cache
19:55.04CosmicPenguinRuss: stupid XScale

20:37.10sorphinno shock there
20:43.57GPSFansorphin: I think the --architecture option should be =mips:isa64 not =mips:5000, only changes a few instructions, after offset aadc.
20:44.13sorphinwhat made you decide that ?
20:46.35GPSFanwell, the 5432 is refered to as being MIPS IV isa, and the instructions that were changed "seemed" to make more sense in the isa64 mode. I'm real new at this so I may be full of $hit.;)
20:48.22GPSFanI did a diff between the 2 disassemblies and looked at the results.
20:49.19GPSFanI was looking to see if using one of the other architectures would make some of the mneumonics created by objdump match what is in the mips 5432 user manual.

20:57.42GPSFantnx
20:57.46sorphindoesn't mean it'll have less instructions total tho :)
20:58.47CosmicPenguinIts along the same lines as a candy bar with less sugar than its competitor
20:59.07CosmicPenguinDoesn't mean it doesn't have a sh*t load of sugar, its just less coma inducing than the next one

21:00.15sorphinCosmicPenguin: speaking of things bad for your health, greg added any more bloat to your list ?
21:02.59CosmicPenguinsorphin: oh yeah - we've gotta make sure that we remove any part of my original design before we release it
21:03.22CosmicPenguinsorphin: but its coming along pretty well
21:03.38CosmicPenguinsorphin: now, all I have to do is rewrite the sync, and then I'll be done with this list
21:03.47sorphinumm
21:03.56sorphin"remove any part of your original design" ?
21:04.23CosmicPenguinsorphin: sure - like for example the directory design
21:04.53sorphinheh
21:17.11CosmicPenguinsorphin: lemme ask you something - if I had ECC in my memory, and I turned it on in the bootloader, would the kernel need to be aware of it, or is it pretty transparent?
21:18.36sorphinCosmicPenguin: the kernel doesn't know the difference fwik
21:18.47sorphinecc is dealt w/ strictly in the hardware
21:19.07CosmicPenguinsorphin: I thought as much
21:19.11sorphinhence why there's a bios flag
21:19.20sorphinin pc bioses
21:19.36sorphinfor whether you want ecc checking (if your mem supports it)
