I found it ! this board is usb powered, there is no VBUS signal, so I tied the VBUS pin to 3.3V and it worked, there is no USB disconnect neither so I have to unplug it on each programming)

I have another question , I have a sdcard-spi adapter that has no signals for card insertion or write ...

Dear Giovanni, thanks a lot for the support, I already bought a discovery f4 board because of the same reason , I discovered Chibios a couple of weeks ago and I love it already, but yes, it's quite complex at the beginnig.

Dear Giovanni, it seems this was a board problem because under oscilloscope, the PA11 pin moves perfectly well (3.3 V swing) and the PA12 pin swings only 0.33 V under any confuiguration (even open drain with pullup).

Thanks again

The board has a STM32F407 and a bunch of peripherals includig 2 USB ...
