Question

Dual core debug

I'm trying to get up to speed on dual core debug on the STM32H745 Disco, using STM32CubeIDE. I've followed a couple of instructional videos that show how to do this.

I've got both cores blinking an led as expected, however whilst the M7 core enters debug correctly, the M4 core fails to enter debug. I have installed the GDB server & CubePROG as the first video suggests.

Clearly I've missed something, but I've tried some other settings to no avail.

Hi @Alexmouse​ ,

Please make sure to follow properly the steps as described in this Application Note AN5361 and precisely the section 3-Debugging.

AN4989 (STM32 microcontroller debug toolbox) may be helpful as well.
