No, that's not a problem. The remote protocol specifies
that, if a
stub receives a packet it doesn't understand, it should send
back the
empty string as a reply. GDB tries using whatever packets
it hopes
will work; if the stub says it doesn't understand them, then
GDB tries
to find other ways to get the job done. So:
> Packet qSupported (supported-packets) is NOT supported
just means that GDB tried to send a 'qSupported' packet to
the stub,
but the stub didn't understand it, and GDB has decided not
to try
that again.
