how to use hardware breakpoints/watchpoints

[Tom Armistead <tiny_armistead at yahoo dot com>]

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
