STM32F4 Bootloader

Post by cimd » Sat Jul 02, 2016 4:32 pm

On github (https://github.com/rogerclarkmelbourne/ ... ootloader/) I could only find a booloader for the STM32F1. Can it also be used for the F4, or is there a specific bootloader for the F4?

And do I really have to upload it through an external USB-Serial adapter? Can't I use the STLink included on the F4-DISCO board?

On F4, the built-in internal ROM bootloader is supporting DFU mode directly without any need for custom bootloader, except if you don't wish to have to deal with switch or jumper on BOOT0 (BOOT0 pulled HIGH while BOOT1 pulled LOW while Reset or power-recycle should bring DFU mode on USBSerial).

About built-in STLink, sure you can use it too.
