Hm, sounds bad.

You didn't answer my question, though. Did you try using a null-modem
cable to see if you get serial debug output? Maybe something's wrong
with your jtag (or other) setup?

Which code exactly are you using? Please send a patch if it's modified
from what is in svn. How are you building LinuxBIOS? How big is your ROM
chip? How big is your linuxbios.rom? What's the contents of your
targets/.../Config.lb file? Which payload are you using? How did you
flash linuxbios.rom on the chip? Are you sure that worked ok?

Do you have a POST card? What does it show? Does it "hang" with a
certain value at some point?

Uwe.

Sorry, I'm not using null-modem cable only JTAG interface, and it's okay
because works with the original bios. I'm using the last msm800sel version
from svn, my flash is 521 Kb, my linuxbios rom plus payload  (FILO) is less
than 64 Kb, I'm not using fallback,  and I use a universal program to flash
the rom and it's okay too because a program the original bios with it.

did you pad the image to the flash size?

You have to have fallback. If you want only one image you need to drop
normal. Normal alone cannot work.

The linuxbios.rom is 521 Kb, just like the flash. I didn't know fallback is
a must to, I'll try a new rom with fallback.
Thanks,

[Otávio Alcântara]

Hello,

I tried to build a new linuxbios.rom with fallback and the file
size ( 1 Mb ) got larger than flash size (512Kb). Follows the
/targets/digitallogic/msm8sel/Config.lb content, I set ROM_SIZE to 521 Kb .

target msm800sev
mainboard digitallogic/msm800sev

option CONFIG_COMPRESSED_PAYLOAD_NRV2B=0

option ROM_SIZE = 1024*512

## ROM_IMAGE_SIZE is the maximum number of bytes allowed for a LinuxBIOS
image,
## not including any payload.
option ROM_IMAGE_SIZE=64*1024

option DEFAULT_CONSOLE_LOGLEVEL = 11
option MAXIMUM_CONSOLE_LOGLEVEL = 11

romimage "normal"
        option USE_FALLBACK_IMAGE=0
        option ROM_IMAGE_SIZE=64*1024
        option LINUXBIOS_EXTRA_VERSION=".0Normal"
        payload /home/otavio/Filo/filo-0.5/filo.elf
end

romimage "fallback"
        option USE_FALLBACK_IMAGE=1
        option ROM_IMAGE_SIZE=64*1024
        option LINUXBIOS_EXTRA_VERSION=".0Fallback"
        payload /home/otavio/Filo/filo-0.5/filo.elf
end

buildrom ./linuxbios.rom ROM_SIZE  "normal" "fallback"

The first thing I ever do with problems of this type is simple:
hexdump romimage

and see if I see a jump at end.

[LinuxBIOS] Digital Logic msm800sel

[Otávio Alcântara]

I used a dissambly and there is no jump in the reset vector. I've tried
other board (amd  rumba, using the same tools JTAG and memory programmer)
and it starts normaly the boot process, just don't finish it because the
processor is a Geode GX and my board is a LX one. I'll try the norwich board
that is similar to mine.
The problem I saw with msm800 is that linuxbios.rom is not on a valid
format, the file doesn't size like the ROM_SIZE option of
targets/../../Config.lb.

Thanks,

Otávio

Are you using buildrom?

http://linuxbios.org/Buildrom

It is recommended to use it for LX systems. It should handle putting the 
VSA image with the LB binary to make the complete image.

Hello,

I used the buildrom tool, but the norwich board uses the companion
serial and my board uses SUPERIO WINBOND w83267hf. So, I modified the code
of /mainboar/amd/norwich/cache_as_ram_auto.c to work with this chip.
        It worked fine, but the boot process stop with :

Before VSA:
do_vsmbios

I'm not including the vsa in the linuxbios.rom, is that the problem?
And how can I concatenate the two files correctly?

Did you have trouble with buildrom-devel? I mean building the packages etc. 
Currently I can't get it to work.

sed tool can be sensitive to locale (in bad way). I have seen that several 
times and the solution is that my estonian default needs "export LC_ALL=en" 
and things start working (especiell configure scripts ). What is your default 
locale and did you have similar trouble?

Hi Indrek,

I didn't get problems with buildrom, the only problem is that it
gets the files from svn and I needed modify some files, so I compiled the
linuxbios by hand.
         My Locale is pt_BR and char set is UTF-8.

You can change buildrom to use a local LB directory:
select CONFIG_ADVANCED
select CONFIG_LB_USE_BUILD

and for CONFIG_LBBUILDDIR specify the full path to your linuxBIOS tree.

This is from my .config:

CONFIG_ADVANCED=y
CONFIG_LB_USE_BUILD=y
CONFIG_LB_BUILDDIR="/home/jcrouse/linuxbios"

We are in some serious need of documentation - but I'm pretty busy.
Any volunteers are gratefully accepted.

Fortunately it was a wrong alarm. I just expected that buildrom is not broken 
in svn :) In other hand I saw that Otávio can be someone who can tell 
something about troubles due to locale settings. Sry, it's time to go home :)

Yes you need VSA2 in the ROM. You can use buildrom in advance mode to 
set a local linuxbios tree. Buildrom pulls the VSA binary from here: 
http://www.amd.com/us-en/ConnectivitySolutions/ProductInformation/0,,50_2330...

un-zip it
"cat lx_vsa.36k.bin norwich.rom >  lb_norwich.rom"
You should end up with a 512KB ROM image.

I should clarify, buildrom can automatically do the LB image + VSA2 
concatenate for you. Follow the instructions to do it by hand.

[LinuxBIOS] Digital Logic msm800sel

[Otávio Alcântara]

I've got concatened both files by hand, I'll try use buildrom next

seems to stop on the usart setup. I'll investigate more later.

Best Regards,

Otávio Alcântara
