Hi

Sorry for my 1st mail. The kernel gets loaded into RAM at 0x400000.

Still, when I issue the 'run' command the target crashes.

limon> run
... crash


Question:

1. Do I have to strip off the elf header from my kernel file?

2. Does the run command relocate the kernel at addr 0?

3. Some data are transferred from limon to the kernel.
 - Does Limon handle this correctly?
 - Where are these data located?

4. Why does it crash?

I guess that answering 3) should solve the problem.....

Thank you for any help

Ruedi
