Program bare stm32h743

All,

I created a dev board myself based on the openMV H7 board.
Its very similar to the openMV, just added some pheripherals.

I’m looking for steps to program a valid openmv bootloader on a bare stm32h743. Any tutorial here ?
Do I have to connect BOOT0 to 3v3 or not ?

Thanks in advance

Yes, the IDE literally tells you what to do when you click connect.

Thanks, than there must be something wrong with the hardware.
The lastest step also fails for me, because it could not find the file:

Ah, yeah, Ibrahim has been generating images without that. Thanks for finding this. This is a bug. Just install the bootloader from here: https://github.com/openmv/openmv/releases/download/v3.9.2/firmware_v3.9.2.zip

OPENMV4/bootloader.dfu

Use the Tools->Run Bootloader to install it.
