I didn't understand...
Sending packet:
$qOffsets#4b...[\x00][\x00][\x00][\x00][\x00][\x00][\x00][\x00][\x00][\x00][\x00][\x00][
r +]Ack
[$][#][0][0]Packet received:
[
w \x00]PC register is not available
What does PC have to do with qOffsets?
Especially when
w \x00]Sending packet: $pf#d6...[\x00][\x00][\x00][\x00][\x00][\x00][
r +]Ack
[$][0][0][0][0][0][f][e][1][#][e][c]Packet received: 00000fe1
and the target is ARM (PC = r15).

Probably nothing. "PC register is not available" means GDB couldn't
source the PC register value from anywhere. E.g., the PC register's
value might be missing from the g/p packet replies.
Debug gdb, and put a breakpoint on throw_it. Figure out from context
and backtrace what GDB is trying to do when that error is thrown.
Thanks,
