mips n64 gdbserver

[Maxim Osipov <maxim.osipov@gmail.com>]

Hello,

I'm trying to debug using gdb/gdbserver on my mips64 -mabi=64 target,
but fail to connect. Below are the protocol logs:

GDB:

Remote debugging using 192.168.0.10:9658
Sending packet: $Hc-1#09...Ack
Packet received: OK

Packet received: T0525:00000055;1d:000000ff;
Couldn't establish connection to remote target
Reply contains invalid hex digit 59

gdbserver:

readchar: Got EOF
[getpkt: discarding char 'ÿ']
Remote side has terminated connection.  GDBserver will reopen the connection.
Listening on port 9658

So, the question - is N64 ABI supported by gdbserver? If so, could you
give me a hint, what this problem could be?

Best regards,
Maxim
