Hi,
I have custom board for stmf401 and I try to program it in DFU mode. I set the boot0 to 1 and reset the chip but it is not recognized as DFU device. (not listed in the DfuSe).
Do I miss any procedure or settings?
(I have connected the PA11/PA12 pins to the corresponding pins in USB).
Thanks in advance.

App Note AN2606 should provide indications if it is supported.
You'd need an external HSE oscillator, that would need to start, and be at a frequency blessed by the firmware, some STM32 had specific expectations, some not, again check AN2606 for specifics.

Yes, I checked the note and it is supported and It did miss the external HSE oscillator for it.
Thank you very much.
