Feb 19 06:35:41 * flyback finds it scary sometimes how music like boards of canada maps out over his dreams perfectely
Feb 19 06:46:18 * flyback goodnight
Feb 19 15:47:33 <flyback-> hey prpplague
Feb 19 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
Feb 19 15:48:15 <flyback-> so I started learning about BMC
Feb 19 15:48:24 <flyback-> man we need to utilitze those at work for our customers
Feb 19 15:48:34 <flyback-> wonder if it's possible to port a os to one :)
Feb 19 15:49:30 <prpplague> flyback-: uh ok
Feb 19 15:50:09 <flyback-> what? they are solid server quality boards good for systems for data recovery etc
Feb 19 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
Feb 19 15:55:04 <bjdooks> anyone had a chance to look at the s3c24xx nand patches?
Feb 19 15:55:47 <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:
Feb 19 15:55:51 <bjdooks> arm920 cp15 0xc0000000
Feb 19 15:55:51 <bjdooks> arm7_9 dcc_downloads enable
Feb 19 15:55:51 <bjdooks> load_image /home/ben/simtec/able-env/able/able.bin 0x30400000 bin
Feb 19 15:55:51 <bjdooks> reg 8  0x04000000
Feb 19 15:55:53 <bjdooks> reg 9  0x04000000
Feb 19 15:55:56 <bjdooks> resume 0x30400030
Feb 19 15:58:53 <bjdooks> bah, arm920 cp15 1 0xc000000 helps
Feb 19 16:00:09 <bjdooks> but doesn't solve the overall not making anything happen
Feb 19 16:07:55 <bjdooks> anyone got any points?
Feb 19 16:08:23 <bjdooks> anyone got any pointers to useful info?
Feb 19 16:08:29 <prpplague> bjdooks: hey guy, where the hell ya been?
Feb 19 16:08:36 <prpplague> bjdooks: sorry, whats the question?
Feb 19 16:09:38 <bjdooks> http://www.fluff.org/ben/openocd-able.txt => doesn't seem to download and run the bootloader image
Feb 19 16:09:57 * prpplague looks
Feb 19 16:11:31 <prpplague> bjdooks: what are reg8 and reg9 being used for?
Feb 19 16:11:36 <bjdooks> memory sizes
Feb 19 16:11:58 <prpplague> ahh
Feb 19 16:12:06 <bjdooks> two 64Mbyte SDRAM banks
Feb 19 16:12:30 <bjdooks> basically we execute post SDRAM init, so we need to supply the sizes so it can lay memory out
Feb 19 16:12:58 <prpplague> bjdooks: so does it even start the bootloader image?
Feb 19 16:13:24 <bjdooks> in fact, load_image isn't doing the right thing
Feb 19 16:14:12 <prpplague> bjdooks: just for kicks try not using the dcc downloads
Feb 19 16:14:47 <prpplague> bjdooks: can you post your .cfg ?
Feb 19 16:14:52 <bjdooks> this could be 'not fast'
Feb 19 16:15:07 <bjdooks> this is svn r281
Feb 19 16:15:30 <bjdooks> sod, that works
Feb 19 16:15:30 <prpplague> bjdooks: ok, grabing a copy now
Feb 19 16:15:41 <prpplague> bjdooks: dcc downloads actually uses a small program
Feb 19 16:15:51 <prpplague> bjdooks: my guess is that it is stepping on something
Feb 19 16:16:32 <bjdooks> working_area 0 0x1000 0x1000 backup
Feb 19 16:17:10 <prpplague> bjdooks: is the sdram initialized at that point?
Feb 19 16:17:14 <bjdooks> yeah
Feb 19 16:17:27 <bjdooks> and 0x1000 is the stepping-stone ram
Feb 19 16:17:36 <prpplague> yea, that was what i was about to ask
Feb 19 16:18:09 <prpplague> hmm
Feb 19 16:18:21 * prpplague looks at the dcc code
Feb 19 16:23:45 <prpplague> bjdooks: try setting the arm920 cp15 after the download
Feb 19 16:24:36 <prpplague> bjdooks: and after the image upload
Feb 19 16:26:01 <prpplague> bjdooks: http://www.pastebin.ca/909885
Feb 19 16:26:10 <prpplague> bjdooks: that seems to work on the hammer
Feb 19 16:26:16 <prpplague> bjdooks: (s3c2410)
Feb 19 16:28:55 <bjdooks> is "arm920 cp15 1 0xc0000000" a valid way of switching to non-mmu mode?
Feb 19 16:33:30 <bjdooks> hmm, it doesn't work with my r208 either
Feb 19 16:33:49 <bjdooks> althoguh i've only ever test that with an arm926ejs
Feb 19 16:35:41 <prpplague> bjdooks: the mmu is configured when you are running this script?
Feb 19 16:36:08 <bjdooks> the point of the cp15 is to ensure the mmy is off, in case something had the time to boot
Feb 19 16:36:45 <bjdooks> the answer seems to be, don't use the steppingstone after boot
Feb 19 16:36:50 <bjdooks> works fine from sdram
Feb 19 16:37:16 <prpplague> bjdooks: ahh
Feb 19 16:37:34 <prpplague> bjdooks: i've used the steppingstone before
Feb 19 16:37:46 <prpplague> bjdooks: there is an openocd command to disable mmu iirc
Feb 19 16:38:49 <prpplague> bjdooks: rtp and i were wondering if you were ok, hadn't seen you online in a while
Feb 19 16:39:48 <bjdooks> been very busy trying to get stuff delivered to customers
Feb 19 16:40:10 <bjdooks> and there's still piles of patches to get to the kernel, cpufreq, s3c6400, stuff like that
Feb 19 16:40:25 <prpplague> bjdooks: oh you got some s3c6400 samples?
Feb 19 16:40:33 <prpplague> bjdooks: we've made a request, but haven't heard back
Feb 19 16:41:20 <prpplague> bjdooks: whatcha think - http://www.elinux.org/Nail_Board
Feb 19 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
Feb 19 16:42:09 <bjdooks> prpplague: i've manahged to get a smdk6400
Feb 19 16:42:15 <prpplague> bjdooks: wow
Feb 19 16:42:40 <prpplague> bjdooks: how did you swing that? ( i assume since you are the 24xx guru)
Feb 19 16:43:30 <prpplague> bjdooks: we start selling the nail at the end of the month for $189
Feb 19 16:44:02 <bjdooks> prpplague: yes, for some reason they'd quite like some s3c6400 support into the kernel
Feb 19 16:44:14 <prpplague> bjdooks: hehe
Feb 19 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
Feb 19 16:44:50 <prpplague> bjdooks: yea, i was just looking at the code in openocd for disabling the mmu
Feb 19 16:45:29 <bjdooks> bah, it seems my stm32f103c pcbs still haven't left china, damn ups
Feb 19 16:47:29 <prpplague> bjdooks: anyway i'll be submitting some patches for the Hammer in a week or so
Feb 19 16:47:39 <prpplague> bjdooks: i'll cc you
Feb 19 16:47:59 <bjdooks> yeah, i'm going to try and start on for-2625 set on monday
Feb 19 16:48:17 <prpplague> bjdooks: whats the window? about a week?
Feb 19 16:48:37 <bjdooks> about 2 weeks, but probably not for another month or so
Feb 19 16:49:11 <prpplague> bjdooks: ahh ok, so we are talking about mid to end of march?
Feb 19 16:49:17 <bjdooks> probably
Feb 19 16:49:36 <bjdooks> i'll probably start a quilt set and keep everyone's patches ready for submitting
Feb 19 16:49:54 <prpplague> bjdooks: this a new machine definition, no problems submitting that for 25?
Feb 19 16:50:17 <bjdooks> those sorts of things are generally merged once 2.6.25 is ot
Feb 19 16:50:46 <prpplague> ot? out there?
Feb 19 16:50:55 <bjdooks> out
Feb 19 16:51:21 <prpplague> bjdooks: so, not worth submitting untill the 26 window?
Feb 19 16:53:41 <drath> bjdooks: hey, saw your post this morning on the list, just didn't have time to reply yet
Feb 19 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
Feb 19 16:54:13 <bjdooks> drath: ok, thanks
Feb 19 16:54:26 <bjdooks> prpplague: submit around 2.6.25-rc5 so it can be revieed and queued
Feb 19 16:54:46 <prpplague> bjdooks: okie dokie
Feb 19 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)
Feb 19 17:20:21 <bjdooks> updated, but still not working, http://www.fluff.org/ben/openocd-able.txt
Feb 19 17:20:35 <bjdooks> i've got to go and get food, might be back before swimming
Feb 19 17:20:46 * prpplague looks
Feb 19 19:47:24 <bjdooks> right, may or may-not be back later
Feb 19 19:52:33 <drath> bjdooks: just committed your patch, thanks a lot!
Feb 19 19:57:32 <drath> bjdooks: the arguments to "arm920t cp15" are a bit complicated
Feb 19 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
Feb 19 19:58:49 <drath> bjdooks: the control register you want to modify uses address 2
Feb 19 20:01:05 <drath> bjdooks: well, maybe there is a direct relationship, but it's still complicated :)
Feb 19 20:01:36 <drath> bjdooks: Table 9-9 in the ARM920T TRM lists the registers that may be accessed via "cp15" command
Feb 19 20:02:17 <drath> bjdooks: Tables 9-11, 9-12 and 9-13 show the accesses possible via the cp15i command
Feb 19 23:10:07 <bjdooks> drath: thanks
Feb 19 23:12:20 <bjdooks> drath: what does it take to get commit access to the svn?
Feb 19 23:51:51 <bjdooks> drath: the cp15i command just times out for me
Feb 20 01:38:34 * flyback is suffering a really bad nosedive fit of depression :/
Feb 20 01:42:17 <bjdooks> i should be in bed, its 0142 localtime
