I have standard powerpc board. u-boot software is already there.
I can download the files through tftpboot command on the board.
I compiled one simple hello program through powerpc cross compiler(GNU). I think a.out is in elf format.
I downloaded this file on target board by giving command "tftpboot 100000 /home/usr/temp/a.out" , then I gave "go 100000".
The board gets reset and starts again.
Can any one help how to solve this problem. The board is from TQC STK5200.

Thanks in advance.
