I did not have mincom running.
I type arm-eabi-gdb -nw DevBoard_install/tests/kernel/v3_0/tests/bin_sem0
at the gdb prompt 
set remotebaud 38400
target remote /dev/ttyS0

After this according to the ecos documentation I should see some information
about the current loaction and language.

What I get is
Remote Debugging using /dev/ttyS0
0x08003b3a in ?? ()

I dont get any extra information.

Is this a problem?

Thanks again

Graham
