Hi Michael,
the fragment of OpenOCD log shows that CPU0 (M7 core) cannot be halted.
What is programmed in M7 startup?

Have you tried using the ST fork of OpenOCD?

Is this of any use?

Hi all,
I'm attempting to get Zephyr working on the M4 core of an STM32H755. I'm using
an ST-Link v3set on Windows 11 with OpenOCD v. 0.12.0.
I am able to flash a compiled binary via OpenOCD, but I have so far been unable
to get to a place where I can debug the second core. I started based on t
