Hi

Im new to ARM9 processors and have the following problem: i want to
run any executable code (that i can change) on my plattform.
So i found the Denx u-boot and can compile it. Then i tried to
download it as stated on the atmel page by setting the jumper to INT
then load the DataflashBoot.bin then load the u-boot to the
dataflash. So far OK, can see the u-boot image at position c0008000.
When i then press '3' it says ..loading bootloader ... but afterwards
nothing happens, things just look like the u-boot hangs (i expect at
least to see u-boot starting up and display a prompt).
I'm using u-boot 1.1.4 and have set TEXT_BASE to 0x21F00000. Also
defined the 2 defines as stated in the atmel introduction.
Anyone knows what's going wrong??

I'm using GNU-toolchain and Eclipse.
Another question is about that DataflashBoot which is actually working
fine. The source code is there as well but i found no makefile, so
i'm not able to compile it. Anyone any idea where i can get it??

thanks & kind regards
Renate

I put my stuff at ftp://at91dist:distrib@xxxxxxxxxxxxx/

Eventually, I should have a Buildroot which will:

1) Build a cross compiler toolchain
2) Build Dataflashboot.bin
3) Build U-Boot 1.1.4
4) Build Linux 2.6.16 (or later)
5) Build JFFS2/EXT2 Filesystem

There is a buildroot there but it has a few problems,
Have not had the time to upload the latest version...
