Hi,
I am having trouble getting GDB (both 5.3 and
5.2.1) to utilize hardware breakpoints and watchpoints
(i.e., the Z packets) with my target. I configured
for a target of powerpc-eabi and everything builds and
runs ok except for the Z packets.
My target stub supports Z packets. I verified it
works by manually sending Z packets to my stub. Using
'show remote' under GDB says that Z packet support is
dynamically detected. So, I would assume that it
would attempt to send Z packets to do the dynamic
detection. But when I try to use hbreak, it says the
target does not support it without even attempting to
send a Z packet to my stub.
My stub supports Z1,Z2,Z3,Z4 but not Z0 if that
makes any difference...
Is there some additional configuration that I need
to do to get GDB to use hardware breakpoint/watchpoint
support?
Thanks,
Tom Armistead
