Trouble installing micropython on Nucleo H743

Post by skysurf76 » Mon Mar 01, 2021 10:21 pm

I have a Nucelo H743 board with a STM32H743ZIT6 processor. I have a micro USB breakout board that has 5V connected to E5V pin on CN11, ground from USB breakout goes to ground pin on CN11 (right below E5V). I have jumper J3 on E5V. I have D+ on the USB breakout going to PA12 on CN12 and D- from breakout going to PA11 on CN12. I am jumpering 3.3V to BOOT0 on CN11 and plugging in the USB cable. The device shows up in windows device manager, but it won't show up in Dfuse.

In device manager it shows up as DFU in FS mode.

Under events for the device it shows...

I found the windows version of dfu-util and it worked.
