Provision to get out of BKPT instruction

techguyz over 5 years ago

Hi Experts,

I am trying to execute the bkpt instruction in Cortex R processor and it goes to halt mode.

Now I would like to retain back the execution without using external Debugger connection. Is there anyway to handle Breakpoint as an exception handler ?

I think, you have to switch to monitor mode. At least it is needed if you use HW watch/break points. Of course, you need to skip the BKTP instruction before returning.

There is an issue with the current version of GDB Server (V5.12g) and the latest GDB (V7.10)
with software breakpoints, resulting in the endless halt/go loop.

This will be fixed in the upcoming version, planned for this week.
