I am developing a STM32F2 device using GCC 4.7.4 and a Lauterbach Combiprobe JTAG debugger. In my code, I have the following statement to always break at a certain spot for testing purposes:
asm volatile ("BKPT #0");
This is the only breakpoint. When I run the program, I can see that my program reaches the breakpoint, but I cannot step beyond this breakpoint using my JTAG debugger. Instead, I have to move the PC counter past this instruction to get the program to execute.
This was working in the past, but I am at a loss to figure out why the behavior is different now. Any clues or hints would be appreciated.
There are so many broken JTAG debuggers. Probably you installed an update for the JTAG adapter?
When you have GDB as Debugger you might check if you can add a macro set PC=PC+4 to a button or key. But if this is possible depends on your IDE.
