I have got trouble to run linux on at91sam9rl64 platform.
I build Bootstrap-V1.6 for at91sam9rlek.
I build u-boot 1.1.5 from linux4sam with u-boot 1.1.5 atmel patch.
I build kernel 2.6.22 from linux4sam with at91 patches.
I modified script from linux_solutions_pack_1_0 to download Bootstrap, u-boot, kernel and rootfs image.
When u-boot load kernel to sdram, it failed due to BAD DATA CRC.
Here is the log file:

I do not understand why the file size displayed by printenv "0x000ED82C" is different from Data Size (972780 Bytes = 0x000ED7EC) from kernel header.
with u-boot, I checked first bytes in SDRAM at address 0x22200000, which are good. I do not find a way to dump all the kernel from sdram to make a diff with original one.

Some ideas about this BAD DATA CRC.

It was due to a bad copy from data flash to SDRAM by u-boot. For now I solve the problem by loading kernel image to SDRAM with Samba tool.
I have got the same problem with the root file system now, the copy in Nand flash is wrong and this with tcl script or Samba tool.
Does somebody already have Nand flash copy issue with samba?
