I'm trying to get my SWD debugger to halt both cores when debugging one of them, but by default it appears to only halt a single core. Looking into the reference manuals for the H755 I see section "63.5.3 Cross Trigger Interfaces (CTI) and matrix (CT...

Hey folks,I'm trying to load firmware onto an STM32H755BI Microcontroller (Dual M4-M7 core). When loading the M7 core with new firmware, I have no issues. However, when I load the M4 core the microcontroller crashes badly. I've tried loading via Cube...

Unfortunately no. My hunch is that the STLink-V3 does not reset some multi-core debug registers that the JLink does, or that the STLink doesn't use proper delays. I think the STLink-V3 needs a firmware patch to fix the issue.

That's interesting. The JLink probe appears to throw the chip into a constant reset state after loading firmware onto the M4 - continuing out of this has the system run normally from start on both cores, even when execution is shown to be halted in G...

How do you trigger dual-core halting on an STM32H755BI?
