| 15:47.33 | flyback- | hey prpplague |
| 15:48.07 | flyback- | friend of mine is giving me some intel 440gx and tyan serverworks IIIsomething server boards with some cpu's, rams and scsi hd's for $50 shipped |
| 15:48.15 | flyback- | so I started learning about BMC |
| 15:48.24 | flyback- | man we need to utilitze those at work for our customers |
| 15:48.34 | flyback- | wonder if it's possible to port a os to one :) |
| 15:49.30 | prpplague | flyback-: uh ok |
| 15:50.09 | flyback- | what? they are solid server quality boards good for systems for data recovery etc |
| 15:50.26 | flyback- | or servers, I Might donate 1-2 to work so we can stop using desktop pc's espically buggy ones for server duty |

| 15:55.03 | bjdooks | anyone had a chance to look at the s3c24xx nand patches? |
| 15:55.48 | bjdooks | i've been trying to write a script to download and exec a new copy of one our board's bootloaders, but i'm not getting any output, the script is: |
| 15:55.50 | bjdooks | arm920 cp15 0xc0000000 |
| 15:55.51 | bjdooks | arm7_9 dcc_downloads enable |
| 15:55.51 | bjdooks | load_image /home/ben/simtec/able-env/able/able.bin 0x30400000 bin |
| 15:55.51 | bjdooks | reg 8 0x04000000 |
| 15:55.53 | bjdooks | reg 9 0x04000000 |
| 15:55.56 | bjdooks | resume 0x30400030 |
| 15:58.53 | bjdooks | bah, arm920 cp15 1 0xc000000 helps |
| 16:00.09 | bjdooks | but doesn't solve the overall not making anything happen |
| 16:02.24 | *** join/#openjtag prpplague^2 (n=dave@mail.americanmicrosystems.com) |
| 16:07.55 | bjdooks | anyone got any points? |
| 16:08.23 | bjdooks | anyone got any pointers to useful info? |
| 16:08.29 | prpplague | bjdooks: hey guy, where the hell ya been? |
| 16:08.36 | prpplague | bjdooks: sorry, whats the question? |
| 16:09.38 | bjdooks | http://www.fluff.org/ben/openocd-able.txt => doesn't seem to download and run the bootloader image |
| 16:11.31 | prpplague | bjdooks: what are reg8 and reg9 being used for? |
| 16:11.36 | bjdooks | memory sizes |
| 16:11.59 | prpplague | ahh |
| 16:12.06 | bjdooks | two 64Mbyte SDRAM banks |
| 16:12.30 | bjdooks | basically we execute post SDRAM init, so we need to supply the sizes so it can lay memory out |
| 16:12.59 | prpplague | bjdooks: so does it even start the bootloader image? |
| 16:13.23 | bjdooks | in fact, load_image isn't doing the right thing |
| 16:14.12 | prpplague | bjdooks: just for kicks try not using the dcc downloads |
| 16:14.48 | prpplague | bjdooks: can you post your .cfg ? |
| 16:14.52 | bjdooks | this could be 'not fast' |
| 16:15.39 | bjdooks | this is svn r281 |
| 16:15.39 | bjdooks | sod, that works |
| 16:15.39 | prpplague | bjdooks: ok, grabing a copy now |
| 16:15.41 | prpplague | bjdooks: dcc downloads actually uses a small program |
| 16:15.52 | prpplague | bjdooks: my guess is that it is stepping on something |
| 16:16.32 | bjdooks | working_area 0 0x1000 0x1000 backup |
| 16:17.10 | prpplague | bjdooks: is the sdram initialized at that point? |
| 16:17.14 | bjdooks | yeah |
| 16:17.27 | bjdooks | and 0x1000 is the stepping-stone ram |
| 16:17.36 | prpplague | yea, that was what i was about to ask |
| 16:18.10 | prpplague | hmm |
| 16:23.46 | prpplague | bjdooks: try setting the arm920 cp15 after the download |
| 16:24.36 | prpplague | bjdooks: and after the image upload |
| 16:26.02 | prpplague | bjdooks: http://www.pastebin.ca/909885 |
| 16:26.11 | prpplague | bjdooks: that seems to work on the hammer |
| 16:26.16 | prpplague | bjdooks: (s3c2410) |
| 16:28.55 | bjdooks | is "arm920 cp15 1 0xc0000000" a valid way of switching to non-mmu mode? |
| 16:33.30 | bjdooks | hmm, it doesn't work with my r208 either |
| 16:33.49 | bjdooks | althoguh i've only ever test that with an arm926ejs |
| 16:35.41 | prpplague | bjdooks: the mmu is configured when you are running this script? |
| 16:36.08 | bjdooks | the point of the cp15 is to ensure the mmy is off, in case something had the time to boot |
| 16:36.45 | bjdooks | the answer seems to be, don't use the steppingstone after boot |
| 16:36.50 | bjdooks | works fine from sdram |
| 16:37.16 | prpplague | bjdooks: ahh |
| 16:37.34 | prpplague | bjdooks: i've used the steppingstone before |
| 16:37.46 | prpplague | bjdooks: there is an openocd command to disable mmu iirc |
| 16:38.49 | prpplague | bjdooks: rtp and i were wondering if you were ok, hadn't seen you online in a while |
| 16:39.48 | bjdooks | been very busy trying to get stuff delivered to customers |
| 16:40.10 | bjdooks | and there's still piles of patches to get to the kernel, cpufreq, s3c6400, stuff like that |
| 16:40.25 | prpplague | bjdooks: oh you got some s3c6400 samples? |
| 16:40.33 | prpplague | bjdooks: we've made a request, but haven't heard back |
| 16:41.20 | prpplague | bjdooks: whatcha think - http://www.elinux.org/Nail_Board |
| 16:41.52 | prpplague | bjdooks: usb powered, has a internal 4 port hub, ft2232 for serial console and jtag, and has the usb slave connected |
| 16:42.09 | bjdooks | prpplague: i've manahged to get a smdk6400 |
| 16:42.15 | prpplague | bjdooks: wow |
| 16:42.41 | prpplague | bjdooks: how did you swing that? ( i assume since you are the 24xx guru) |
| 16:43.30 | prpplague | bjdooks: we start selling the nail at the end of the month for $189 |
| 16:44.02 | bjdooks | prpplague: yes, for some reason they'd quite like some s3c6400 support into the kernel |
| 16:44.14 | prpplague | bjdooks: hehe |
| 16:44.27 | bjdooks | ok, so "arm920 cp15 1 0xc0000000" doesn't seem to do what i want in the way of disabling the mmu |
| 16:44.50 | prpplague | bjdooks: yea, i was just looking at the code in openocd for disabling the mmu |
| 16:45.29 | bjdooks | bah, it seems my stm32f103c pcbs still haven't left china, damn ups |
| 16:47.30 | prpplague | bjdooks: anyway i'll be submitting some patches for the Hammer in a week or so |
| 16:47.39 | prpplague | bjdooks: i'll cc you |
| 16:47.59 | bjdooks | yeah, i'm going to try and start on for-2625 set on monday |
| 16:48.17 | prpplague | bjdooks: whats the window? about a week? |
| 16:48.37 | bjdooks | about 2 weeks, but probably not for another month or so |
| 16:49.12 | prpplague | bjdooks: ahh ok, so we are talking about mid to end of march? |
| 16:49.18 | bjdooks | probably |
| 16:49.36 | bjdooks | i'll probably start a quilt set and keep everyone's patches ready for submitting |
| 16:49.55 | prpplague | bjdooks: this a new machine definition, no problems submitting that for 25? |
| 16:50.17 | bjdooks | those sorts of things are generally merged once 2.6.25 is ot |
| 16:50.46 | prpplague | ot? out there? |
| 16:50.55 | bjdooks | out |
| 16:51.21 | prpplague | bjdooks: so, not worth submitting untill the 26 window? |
| 16:53.41 | drath | bjdooks: hey, saw your post this morning on the list, just didn't have time to reply yet |
| 16:54.06 | drath | bjdooks: i'm still in the office, but I'll have a look at your patch and your cp15 problem when i get home, about 30 minutes |
| 16:54.13 | bjdooks | drath: ok, thanks |
| 16:54.26 | bjdooks | prpplague: submit around 2.6.25-rc5 so it can be revieed and queued |
| 16:54.47 | prpplague | bjdooks: okie dokie |
| 16:56.27 | prpplague | bjdooks: yea, we've got a number of folks beta testing the nail board, basically using it as a hardware qemu(yea yea oxymoron) |
| 17:20.21 | bjdooks | updated, but still not working, http://www.fluff.org/ben/openocd-able.txt |
| 17:20.35 | bjdooks | i've got to go and get food, might be back before swimming |

| 19:52.33 | drath | bjdooks: just committed your patch, thanks a lot! |
| 19:57.32 | drath | bjdooks: the arguments to "arm920t cp15" are a bit complicated |
| 19:58.28 | drath | bjdooks: there's no direct relationship between the addresses used to access the cp15 via jtag and the mrc/mcr opcode fields |
| 19:58.49 | drath | bjdooks: the control register you want to modify uses address 2 |
| 20:01.05 | drath | bjdooks: well, maybe there is a direct relationship, but it's still complicated :) |
| 20:01.36 | drath | bjdooks: Table 9-9 in the ARM920T TRM lists the registers that may be accessed via "cp15" command |
| 20:02.17 | drath | bjdooks: Tables 9-11, 9-12 and 9-13 show the accesses possible via the cp15i command |
