STM32H745: Dual-Core Bootloader I plan to implement a custom bootloader for dual-core device STM32H745. Can I just use 1 bootloader on CM4 side and flash the images for CM4 and CM7? Thanks!

Yes, this is viable. You'll need to ensure only the CM4 starts up, then start the other core in your program if needed. Or use the CM7 as bootloader. Both cores have access to the entire FLASH space.

Thank you for the quick answer. Using CM7 as bootloader seems easier for my project.

@TDK when you say "You'll need to ensure only the CM4 starts up, then start the other core in your program if needed." ... any clues on where I might find how to do this.
