I suspect it is not functional in the F4, since it seems to have the page_size set to 2KB max for any configuration, and the F405/7 and others have larger page sizes.
Also the aeoquad32 official page seems to indicate the bootloader in that board (based on F405) is the internal one. There are instructions to load the Firmware using DfuSE.

i agree, it may never have worked...

The code to flash the LED works, and it flashes at the correct speed, so the code for the PLLs and the GPIO etc must be OK, but it doesnt numerate USB.

i did try to find where the code came from, as the commit comment mentions ist from ala42 but that github account is completely empty.

i will PM gbulmer about it, to see if he cam shed more light on its status

PS. The reason I was looking at it was, that it should work with the existing dfu-util and bat files etc, also it compiles to less than 8k ( but size if not so important on the F4)
