[U-Boot-Users] at91rm9200 - silent console

[Craig Robinson]

Hi Leonid & Ulf

Thank-you for the pointers to the atmel patched code and buildroot scripts. 

Can I confirm with you that the correct way to set up u-boot for an
at91rm9200 is to use two boot loaders. Can I also confirm that, to boot from
parallel flash, the first stage boot loader is boot.bin and that this will
load a gzipped version of u-boot. The fact that the atmel source from Ulf's
ftp generates a gzipped binary when built suggests to me that this is so.
I've seen different opinions on the newsgroup, including some pretty
emphatic ones from Wolfgang that u-boot will just work on its own, and
frankly am a bit confused! 

If u-boot should be started by boot.bin are there any specific CONFIG
settings to go along with this? Eg. do we need LOWLEVEL_INIT or not? Also
I'd be grateful if you could point me at the CONFIG (if any) needed to boot
from parallel flash and not dataflash. I think this used to have something
to do with CONFIG_BOOTBINFUNC but now that's been replaced...?

Many thanks
Craig

Unlike more "traditional" PPC versions of u-boot, at91... U-boot is not
the first code running on the board. The first one is normally some
small bootstrap, running from dataflash or flash itself - it depends on
jumper settings and also u-bbot configuration must be right. 

Search this list's archives - this question has been discussed many
times in different forms.

Leonid.

Dear List

I have a at91rm9200ek based board on which I am trying to get u boot
1.2.0 running, without success. 

I have also tried to compile and run u-boot for the ek directly from the
source, all be it with unmodified at91rm9200dk_config. This does not
work either. When I load the uboot.bin into flash (with a J-Link ICE) at
0x10000000 and reboot I get nothing on the DBGU console. Is this what
you would expect for an ek board with un-patched 1.2.0 source?
