So this target supports qfThreadInfo, but then it's returning an empty thread list... remote_update_thread_list will delete threads from GDB's list that are not found in the thread list that the target reported. Why is the target reporting that empty list? See ab970af19746364a4f236bebc238ebb036adc898. We may be able add a workaround for this. :-/ Just in case, can you confirm that the current thread's ptid (inferior_ptid) is magic_null_ptid? > Sending packet: $Hc-1#09...Packet received: > Sending packet: $qC#b4...Packet received: unset Thanks, Pedro Alves
