On the working boards, the issue that people can run into is that the wrong driver is configured for a given mode, so they try and dfu-util to a device which windows thinks is a CDC ACM serial port, or tell windows that the dfu mode is a serial port.īut in this case, on the 3.1 boards, once dfu-util has been "successfully" run once, it will always boot in DFU mode (PID=0xef99) from that point. (I've read a lot of places where people seem to have the mistaken impression that Zadig tells the board what mode to be in, or even that Zadig somehow tells dfu-util where to install the firmware).
