Question about USB flashing.

Hello,

I am a student currently working on my diploma thesis, which is focused on the Nordic nRF52840. I have designed a custom board that is functioning well. At the moment, I am flashing it using a J-Link programmer, but I would like to utilize the D+ and D- lines of the USB interface.

My VS Code project is based on the Nordic nRF52840 DK, along with my custom overlay. Is it possible to flash the board and read data directly via the USB? Currently, I am only using the USB port for power, but in my design, I have connected the D+ and D- pins.

Thanks,
