Hi. I wonder how risky a firmware update is. I want to flash a firmware I built myself, using DFU as described in https://github.com/folknology/IceCore/wiki/Updating-IceCore-firmware
Is the board always recoverable via DFU even if I somehow mess up the build and flash a broken firmware?
This should be fine as we have the µC managing things
However I cannot provide a total guarantee, some of it will be down to ST DFU code for example..
The DFU is in ROM within the STM32, so it should be impossible to brick, was my understanding.
I haven't yet managed to brick one BTW
