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.

Hi guys,

I have encountered a problem when debugging programs that issue a bkpt instruction using a J-Trace Cortex-M. I had originally posted the bug to GNU ... be an issue in the GDB server implementation provided by SEGGER: ..... I was hung up on this problem for a while, and I appreciate you guys fixing this!
