Hi,
I was playing around with my STM32h745I-Disco and did some tests regarding starting and stopping the CM4 from the CM7. But I accidantly messed my the option bytes up. I disabled BCM7 and BCM4 with CubeProgrammer and now the chip is not starting anymore. But I can also not connect to with the embedded ST-Link to recover the option bytes. Is there a way to get the board back to work?
Thank you and best regards
Philipp

Use the "STM32 ST-LINK Utility" to connect to the board using access port 3 (under Target -> Settings), then change the option bytes back.
