[STM32F469 DISCO] - How to enter DFU mode

Post by hegauwolke » Tue Dec 08, 2020 10:18 am

Hello all,
I found an old an unused STM32F469 DiSCO board and want to flash it with micropython. I am not able to enter DFU mode because a cannot find the BOOT0 Pin to enable flashing.

Does anybody know how to flash that board with Micropython?
Thanks

You may use onboard stlink to flash hex/bin format firmware.

Thanks,
does it mean, that I have to convert the dfu file into hex/bin format and flash it with st-link?

When you build the firmware it produces a firmware.elf file which can be used to generate the .bin file used for st link.

If you build the firmware you can then do:

Code: Select all

make BOARD=STM32F4DISC V=1 deploy-stlink
to see the commands needed to generate a .bin from the .elf
