Other packets produce on gdbserver-7.6: > Sending packet: $MustReplyEmpty#c4...Ack > Packet received: E01 MustReplyEmpty is actually not a useful probe packet, because that's actually an M (write memory) packet, which is then misinterpreted and fails the write. So not an unknown packet. Try qMustReplyEmpty or something like that instead. Thanks, Pedro Alves
