rtems samples crash

[Thomas Doerfler]

Lukasz,

obviously you are trying to run executables which should run on your
"virtex" board in the gdb-integrated simulator "psim" (that's what the
line "tar sim" is for. Since the simulator does not know anything about
the "consolelite" serial port, it crashes when it tries to access these
registers.

You should try to connect via gdb to the target board (have a look at
the current xilinx EDK documentation on how you can download the
executable to the FPGA.

wkr,
Thomas Doerfler
