gdbserver /gdb use on ARM/XScale help

I inherited a distribution for an IXP420 Xscale processor and tried to use gdb without success. This is what I get on the target and on the host (Debian). I did a search on this and it seems that :

  1. I have to apply a patch
  2. The cross-compile was not done properly
  3. I have to upgrade my gdbserver.

Any insights? Thanks.

are you talking about gdbserver from .deb packages ? If you download GDB 6.3, you should be able to cross compile it yourself for the arm-linux target. No other patches, but you do need gdbserver 6.3 too. I use that for the IXP425, and gdb/gdbserver runs fine.

regards,
