Dear os user,

I want to boot linux by a simplified bootloader. I use Atmel's ARM chip (AT91SAM9RL64EK board). Now, I can boot linux with my small program. The small program will parse the image generaed by "mkimage"

and sometimes the sytem even crashed when R/W filesystem.
But with the same linux kernel and rootfile system, if I use U-Boot to boot linux, everything seems OK.
Can anyone tell is there any trick that's related with linux NAND driver in U-Boot? Or any suggestion to help me moving on?
Well, you already mentioned the solution: either use U-Boot, which seems to be working fine, or fix your own program such that it performs the same intializations like U-Boot.
Be careful when copying code from U-Boot - U-Boot is under GPL, and you may quickly find that you have to release your program under GPL, too.
Best regards,
