Only MatCat could tell, but I think it should be fine...

My dfu builted on Windows doesn't work.
It flashing the screen and restarting over and over with a 1s cycle time...

EDIT: Nop, my bad, it is working! I forgot to copy the filesystem dir...

Then it didn't completely fail, since that is the watchdog kicking in

Did you try using the stm32.zip I supplied? If you get the same result with that then it is likely the code as opposed to the toolchain. By the way you can install it wherever you want as long as it is in your path, so you can have both toolchains installed simultaneously.

Sorry! It works!
I forgot to copy the content of the filesystem dir...

Compiled size of the complete FatFs Module and of this one ultra-embedded.com/?fat_filelib to be tested.

I'd also check out ELM. Make sure you can change the sector-size, since we require 4096k sectors.
