Hi all,
i'm trying to use the u-boot on an at91sam9260ek board, i cannot start successfull the u-boot binary.

build u-boot 2011.09:
export CROSS_COMPILE=/opt/arm-2010q1/bin/arm-none-linux-gnueabi- /MAKEALL at91sam9260ek_nandflash

load & start:

I don't have problems running the linux4sam u-boot binary,
using the same commands. ftp://www.at91.com/pub/uboot/u-boot-1.3.4-exp.4/u-boot-1.3.4-exp.4-at91sam9260ek-nandflash.bin

I'm making something wrong?
Someone can help me?

Thanks in advance for any help

Hi Fabio,

I believe the at91 U-Boot that Atmel publish has some patches applied. I don't know offhand what they were but it would be worth checking that these have made it into the current builds.

http://www.at91.com/project-community/article/2-Projects/218-at91-u-boot
-bootloader.html refers.

Out of interest, have you had any problems with 2010q1 compiler? Atmel told me a while back they only advise the use of 2007q1. I found that later compilers gave problems, though I can't remember what they were now.

Cheers
John

Well, it is not clear to me why you want to run u-boot as single application, instead of replacing the version you have now on target. And why are you loading u-boot at 0x22000000, because if I see in the include/configs/at91sam9260ek.h CONFIG_SYS_TEXT_BASE is set to 0x21f00000...

Apart of that, you should also check the bootstrap code (not part of u-boot), and maybe you have to fix it if the addresses do not correspond or a smaller image from NAND flash as u-boot is copied.

Best regards,
Stefano Babic

Loading u-boot at 0x21f00000 solved the issue! Thank you very much! I'm loading as single application, because if make some mistake it's faster to change the binary, and it's easy to change the load address too.

Now i check the bootstrap code for the correct load address.
