first of all, I am a newbie in embedded linux systems.
I'm trying to boot a board based on a MPC8560 (with a e500 core).
I'm using a RS232 console via a debug module connected to the SCC1 port of
The boot loader is U-Boot.
It appears that the transfert of the kernel from the host to target is OK
(I'm using TFTP).
Problems begin when I try to execute the kernel. The system appears to be
I don't know if the board is really frozen or if I have "only" lost the
I suspect that my error is situated in the load/execution addresses.
I've tried different couples of values : 0/0, 100000/100000, 10000/10000,
I've also tried different file format (uImage, zImage.elf, zImage.s ...)
I've tried two distributions : ELINOS and DENX.
I don't know what's happened because I lose the console .
Here is the result of one of my tests :

Client IP Address (0 for unknown) = 192.168.001.126 ?
Client address mask (0 for unknown) = 255.255.255.000 ?

After that, the console is died !
I could use some help in trying to understand what's going on.
