[Buildroot] BR 2012 & pandaboard :: BOOT issue

[Buildroot] BR 2012 & pandaboard :: BOOT issue

[MERCADIER Johann]

Hi,
   with BR 2011.11 I couldn't boot using MLO/u-boot.bin/uImage generated
while building a basic system. I then change to BR 2012 and I still have
the same problem. When using the one provided with an "Ubuntu" distro it
start to boot.
   I have tried different options for the "boot.script" file called
boot.scr and nothing improve it.

   I then have 2 questions:
     i)    Where it is possible to find documentation to write correct
boot.script? as the pdf doc. I found doesn't mention anything helpful
according to the memory mapping. On the net I have found different value to
start the boot process which one is the good one?...
     ii)   Why even the uImage created doesn't work, How using BR I can
generate correct boot files? I have tried to use MLO/u-boot.bin couple from
an Ubuntu distro and use the uImage generated by BR then I got an error
message telling me that it couldn't find the kernel!

   I don't know how to solve this problem neither what I could test next to
make thing going ahead? If you have any ideaS there are welcome!

thanks.

Here are some infos on my toolchain built using BR, I didn't not find much
difference with yours Yegor but for the newbie I am, I probably miss
something?...

I will try to compile uboot on its own without using BR and see if the
things get better?
If you have any other ideaS I will be please to read them!

Just try ct-ng toolchain (BR2_TOOLCHAIN_CTNG) with default settings
and let us know if it helped.
