osk5912 boot failure with u-boot 1.1.4

osk5912 boot failure with u-boot 1.1.4

[Martin Margraf]

hi,

i compiled u-boot 1.1.4 with ELDK 4.0 and put it to my osk5912.
but now my board does not boot anymore. how can i fix this?

if i boot my board with u-boot 1.1.2 there is a conflict with the machine number.
the u-boot machine number is 3 and the kernel machine number is 203??
can i change the machine number in u-boot? 

regards

martin

You need to compile u-boot 1.1.4 using eldk-3.1.1.
I have tested it and it works fine.

Hello,

To restore your OSK with a working u-boot bootloader, you would need CCS on Windows and an emulator.  More details on restoring a board can be had from 

http://omap.spectrumdigital.com/osk5912/factoryconfig/

I tried a u-boot-1.1.4 version compiled with ELDK 4.0 on my OMAP5912 OSK but it didn't boot aswell.  One of the reasons for this could be because of versions of the OSK boards, based on the processors they come with.  There is a Rev. C board (the processor on these boards reads as an XOMAP) and there is a Rev. D board (the processor on them read OMAP or POMAP).  If your board is a Rev. D one, then some changes specific to the POMAP/OMAP needs to be made in the u-boot sources.  A list of these changes can be found at the Spectrum Digital site:

http://omap.spectrumdigital.com/osk5912/osk5912_faq.html

At the above site, check 
- Section 10. Versioning 
- Section E. Errata

With these changes in place, I was able to build a working u-boot-1.1.4 bootloader for my Rev. D OSK board using the ELDK-3.1.1 toolchain. 

Hope this helps,

Warm regards,
Kanagesh

osk5912 boot failure with u-boot 1.1.4

[Martin Margraf]

so, i compiled u-boot 1.1.4 (latest version from ftp://ftp.denx.de/pub/u-boot and with the patches available from http://omap.spectrumdigital.com/osk5912/osk5912_faq.html)
and my 2.6.16.18 kernel with ELDK 3.1.1 and i get the following error.

#OMAP5912 OSK # bootm 0x100000
### Booting image at 00100000 ...
#   Image Name:   Linux Kernel Image
#   Image Type:   ARM Linux Kernel Image (gzip compressed)

these are the settings i made in the kernel .config:

system core type: 
CONFIG_ARCH_OMAP=y
omap core type:
CONFIG_ARCH_OMAP16XX=y
omap board type:
#CONFIG_MACH_OMAP_OSK=y

I think I mentioned this a few times on this list. Please *don't* use any 
older versions of U-Boot. Even not 1.1.4 release from end of last year. 
Please use current top-of-git tree version:

http://www.denx.de/en/Software/GIT

I integrated the patches from Spectrumdigital a few weeks ago in this version. 
For those without git access I attached the OMAP5912OSK binary.

Hope this helps.

Best regards,
Stefan

Your u-boot passes wrong machine ID to kernel (3, should be 
0x203). So your kernel should be correct, but your u-boot 
seems to be wrong. Looking at

http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;h=6993b136eebbf10cfdf1c678958ab4b6d3162577;hb=392c252efd5d2e67b47ebeb3b7e4f42e7e3d5127;f=board/omap5912osk/omap5912osk.c

recent u-boot passes the correct number if build correctly. 
Do you really built u-boot with

make omap5912osk_config
make

?

Dirk
