Hi Derrik Weeks,

I got the bash prompt.

A little research says this is not the case.  As I understand it (with thanks
to Wolfgang) Linux reserves memory space below 80000000 for user
applications.  In my case I had my IMMR based registers mapped below this
value, and the kernel was setting mapping for this space to virtual =
physical, which caused my problem.  You may have the same issue with your
serial port, it would be worth a try to move it to high memory and see if
this resolves your problem.

I changed the hardware by some jump wire, so the serial port is now located at 0xff000000.
I'll try the virtual != physical thing with my original hardware.

Thank you for the reply!
