Subject: RE: [openrisc] or32-uclinux-gdb
The target's embedded OS may typically wait for a string which is terminated
by an LF before packaging it up in a GDB remote debugging protocol string
packet and sending it to the host. I am guessing that the difference you see
may be down to the way the different operating systems handle the GDB remote
debugging protocol, assuming of course that you are a) running your target
with RTEMS and debugging with or32-rtems-gdb and b) running your target with
uCLinux and debugging with or32-uclinux-gdb.
You could try doing 'set debug remote on' if you're using serial debugging;
'set debug target on' may also help.
