While debugging my application, with GDB, if a watchpoint hits when in = a xenomai RT thread, the machine hangs. If I connect the JTAG probe, I get core 1 halted with message "Synchron= ous Watchpoint", with PC being on the instruction that should have trig= ged the watchpoint. From that point, I can never get GDB or the app to = continue. I can (using the JTAG debugger) hit continue, but it seems th= e app stays hung (even kill -9 does not terminate it and I have to rebo= ot the target. Can anybody help ? Thanks in advance Fran=C3=A7ois
