Hi,
I am doing remote debugging using GDB Server running on ARM based target.
My HOST is a i386 based Linux box.
When I say:
(gdb) mt packet g
The reply is :
01000000e4fdffbfecfdffbf43000000e4fdffbf040f02405c82000001000000a0830000ec77

0000000000000000000000000000000000000000000000000000000000000000000000000000
0000000000000000000000000000000000000000000000000000000000000000000000000000
00000000000000000000000010000060
which I think maps to:
{"r0", "r1", "r2", "r3", "r4", "r5", "r6", "r7", "r8", "r9", "r10",
"r11", "r12", "sp", "lr", "pc", "f0", "f1", "f2", "f3", "f4", "f5",
"f6", "f7", "fps", "cpsr" };
My question is:
If I were to access the BANKED registers (like R8_fiq, R14_abt etc..) of
ARM, will the existing GDB Server architecture would suffice my need? Or in
other words, How can I achieve this?
Thanks,
Manoj

The current GDB protocol used for ARM doesn't support those registers.
You'd probably want to add support for p/P packet register fetches and
query them that way.
Note that the current GDB _client_ doesn't support them either.
