Hi.
I finally got Linux running on my board, thanks to Wolfgang.
My problem was that I placed the internal memory map at 0x1F00000, and that
won't work.
Here is Wolfgang's explanation why:
This will not work. You will have to change your address map so IMMR
is above 0xD0000000; usually 0xFFF00000 is a good value to use.
The reason for that is that the IMMR / DPRAM area needs to be mapped
as physical memory prior to the kernel VM initialization, the mapping
being virtual to physical. This happens in mm/init.c for things like
the IMMR and some other board control registers. In this case,
mapping below something like 0xD0000000 causes problems with VM
collision in kernel or user process space.
Thank you.
