 Hello,

Problem may me with linux kernel image. make sure your image is u-boot 
valid. (make uImage when compiling kernel or doing "mkimage" of the 
linux image).

U-boot commands I use:
    tftp ram_add LINUX_UIMAGE
    bootm

I hope this can guide you a little

Regards,

Víctor.

Hello,
I've ported the U-Boot to my own board. I am using a MPC866.
I compiled with the option of -DDEBUG, so I can see the debug messages. I
try to load an Linux kernel image, but after checking the image and
uncompresses it, the following message appears:
"Transferring control to Linux (at address 0x00000000)".
So I think U-Boot has already finished, hasn't it?
My problem is that after this message, the kernel hangs.
Moreover, it is supposed that the Linux kernel is uncompressed in the
address 0x00000000 (at least for PPC), but I do not see it there.
I am not sure if the problem is in my kernel image or in the U-Boot and
where.
Can anybody help me?
