I got this message when I tried to remotely debug a
mips64-octeon-linux gdbserver 6.8 with GDB >= 7.5.

GDB <= 7.4.1 works well, but with 7.5 and up I receive this message
and the debugger stops functioning.


I suppose GDB 7.5 is slightly incompatible with older gdbserver versions.

What kind of target description does gdbserver return in this case (set
debug remote 1)?


Full log attached. Thanks for your help.

Strange. If this is gdbserver 6.8, it should've replied to theqSupported packet? That one was added in 6.6.
