gdb/gdbserver TQM885

[oparz]

Hello,
I have a problem on debugging my target board TQM885 (ELDK, Linux
2.4.25) with gdb/gdbserver . My Testprogram is a simple helloworld. The
program itself is running as expected, but its not possible to debug.
Would be very  glad, if anyone can help me. Target and Host are in
different subnets, but this is solved via route add.. command

That's wrong. You cannot use a native x86 GDB to debug a PowerPC
system.

Here it's telling you that it has problems to understand the other
architecture.

Use the ppc_8xx-gdb that comes with the ELDK instead. And make sure to
read the DULG, especially the hints about setting
solib-absolute-prefix

Best regards,
