STM32F411E-DISCO DFU Issues

Hello all,

I am having a difficulty trying to get my STM32F411E-DISCO board to go into DFU mode. After applying power to the mini USB connector (USB ST-LINK), the default program operates. I then want to go into DFU mode so I have the the power cable in the mini USB and a micro USB plugged in for the DFU and I bridge BOOT0 to VDD with a jumper and press RESET and the board will not connect to DFU. All that happens is the main demo program stops operating. Any insight as to why this is happening? I did the exact same thing on my STM32F407G-DISC1 and I can get to DFU without any issue.

Any help that can be given will be greatly appreciated. Thank you in advance.

Hi All,

I discovered the reason for the error. The

STM32F411E-DISCO

was missing the solder bridge (SB20) that pulled PB2 to a low state. Putting the jumper on PB2 made it work. ^-^v

Hope this will help someone else with a similar issue.

Thanks Aron,

This was useful! Faced exactly same issue, on exactly same board and the jumper from PB2 to GND fixed it.
