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.
Is this the correct bootloader for STM32H743?
Hi, the IDE will recover the bootloader for you automatically. Just click connect without a camera attached and follow the prompts.
I’m not seeing the option for recovering without a camera.
I’m also not sure which firmware to use.
My custom board has the STM32H743.
Thanks in advance!
Just click connect in the IDE with no camera attached and it will walk you through how to recover it.
