Communication with STM32 NUCLEO-F767ZI without using USB (CN1)

I got this STM32 NUCLEO-F767ZI. The USB port (CN1) on it got broken.

I know I can power the board from Vin, but is there a way I could upload the code / communicate with board without  using CN1 (USB port).

Thanks

I really don't like these micro-USB connectors for development boards.

It is going to be difficult to program the board. You'd want to connect to the CN4 pin header, ie remove jumpers and attach an ST-LINK or other debugger pod to the Target side SWDIO/SWCLK pins of that header to program the board via SWD. You might want to remove solder bridges connecting NRST to the on-board ST-LINK you can no longer use.

To communicate you'll want to look at connecting to a USART via appropriate pins, and USB-to-CMOS Serial type dongle.

USART1/USART3 might permit connectivity to the System Loader and the Flash Demonstrator application. Check docs and app notes for using the System Loader ROM via BOOT0=High
