I don't get any output. If I use the BDI, it stops at line 569
in start.S: STD_EXCEPTION( 0x1400, DataTLBError, UnknownException)
I guess this is even before relocation to RAM.
Does that make sense?
Im also not sure with the BDI output - my config-file is a
result of trial&error. Maybe you could
send my a valid BDI config file for debugging?
