Software breakpoints with J-Link probe

[Christopher]

Hi,

I am not able to make software breakpoints working with a Segger J-Link probe.

As an exemple, here is my assert callback function:

void __attribute__((noreturn)) __assert_func(const char *file, int line, const char *func, const char *failedexpr) {
  asm volatile("bkpt");
  abort();
}

My program should be stopped automatically when entering any assert function. In general, I would like to stop the execution of my program using the asm volatile("bkpt") instruction.

Using an ST-Link v2 probe, the code above works. Unfortunately, it doesn't work with a Segger J-Link probe. Any experience with this ? Is any specific configuration require to make this working ?

Note: I use the latest available J-Link firmware "SEGGER J-Link Lite-Cortex-M V8.00" with SEGGER J-Link V5.12 software.

Thanks @hungbui, unfortunately your code is not working with my setup. I will also try it with Keil. Maybe there is something wrong in my Eclipse / J-Link configuration. Any help is welcome.
