Hi,
I want to see any changes that are performed to a specific memory
area. So, I set a watchpoint with wa *(int*)0xXXXX and continue the
execution. Then, I get the GDB errror message:
Can't clear hardware watchpoints without the 'Z2' (write-watchpoint) packet
Any ideas what's wrong?
Regards,
Chris

The error message is not helpful, but the problem is usually that your
remote target does not support watchpoints. I believe the error
message is somewhat improved in HEAD gdb.
