| 11:22.59 | iddqd | hi, All. |
| 11:23.31 | zumbi_ | hi iddqd |
| 11:23.57 | iddqd | can i have little help with booting linux on pxe270 machine? |
| 11:24.25 | zumbi_ | do you know who is ben dooks is in IRC ? |
| 11:24.47 | iddqd | sorry? |
| 11:24.55 | zumbi_ | iddqd: i dunno handhelds, but what is your problem? |
| 11:25.27 | iddqd | the problem looks simple: just plain hangup right after haret jumps to kernel |
| 11:25.55 | iddqd | in haretlog.txt i have last line `Go Go Go...' and thats it |
| 11:26.40 | zumbi_ | wow, i have no idea, maybe someone else in the room can help you -- sorry |
| 11:27.58 | iddqd | zumbi_:little googling gave me "From: Ben Dooks <>" on LKML. you've told me about him? |
| 11:30.39 | zumbi_ | iddqd: yes, he codes kernel stuff for the samsung chips |
| 11:31.10 | zumbi_ | i am after him because i want to know where are his latests changes on s3c adc driver |
| 11:33.31 | iddqd | never heard about him :-). i'm a very newbie in linux on arm. and in linux hacking also. |
| 11:34.50 | zumbi_ | i have always been a newbie :-) |
| 11:36.37 | iddqd | it's kinda hard to dig information about low-level stuff. and therefore the only way is to do try-and-error method. |
| 11:37.20 | zumbi_ | i disagree, there are lots of info, it just takes time to understand (read the code, luke !) |
| 11:37.47 | iddqd | i tried about 10 different kernels (inculded self-compiled) and none of 'em worked. |
| 11:38.02 | zumbi_ | the learning curve in embedded stuff it is somehow long |
| 11:38.14 | iddqd | every kernel just hung. not even printing "Unpacking Linux..." |
| 11:39.26 | zumbi_ | was the bootloader passing the right args to the kernel? did you have the right machine ID? those are some things you need to check |
| 11:41.01 | iddqd | ah, my other question was right about `mtype'. what has `arch/arm/tools/mach-types' to do with compiled kernel, bootloader, etc? |
| 11:41.15 | iddqd | is it user somehow during kernel build? |
| 11:41.24 | iddqd | s/user/used/ |
| 11:41.33 | iddqd | lol |
| 11:42.48 | zumbi_ | yes, mach-types are used |
| 11:43.11 | iddqd | then i wonder, how do i set it during kernel build? |
| 11:44.07 | zumbi_ | iddqd: you might have to give a value to some env variable in your bootloader |
| 11:47.16 | iddqd | my bootloader (haret) is pretty good at it. at least it passes correct MTYPE to kernel. |
| 11:47.34 | iddqd | but how do i know whether kernel supports that MTYPE? |
| 11:48.24 | zumbi_ | look the mach-types file |
| 11:50.23 | iddqd | and? a believe, that for my hx2490b MTYPE is 709. at least hx2750 is very similar to it. haret writes in its log that exactly that MTYPE is passed to kernel |
| 11:51.51 | zumbi_ | hx2750MACH_HX2750HX2750709 |
| 11:51.59 | iddqd | yep |
| 11:52.05 | zumbi_ | hx2750 MACH_HX2750 HX2750 709 |
| 11:52.31 | zumbi_ | i dunno if you need another mach type |
| 11:53.28 | iddqd | what i'd like to know is how do i set MTYPE for kernel _building_? if it really matters. |
| 11:58.42 | zumbi_ | i dunno, maybe http://www.glomationinc.com/PortingLinuxKernel.pdf can help you |
| 11:59.39 | iddqd | thanks. lets see... |
