Hi,
didn't have any problems with luftboot on the F1, but to my knowledge
luftboot hasn't really been used much on the F4.
And I know other people had issues with flashing F4 via stm32_mem.py...
We will do some more porting of our software to the F4 at the end of April,
so I guess we will have to look into that...
Suggestions welcome :-)
Cheers, Felix
