nrf5340pdk and I see three comports in Windows when I plug it in.

Hi

I have a nrf5340 pdk version 0.8.0  (PCA10095)

When I plug it into my Win 10 (latest version 2004) device manager tells me it sees 3 comports

When loading the 'Peripheral UART'  sample app, how do I know one of those 3 comports I need to open?

What are those ports connected to on the PDK?

Look forward to hearing from you

Kind regards
Mahendra

  • Hi,

    Of the three COMs, one goes to the nRF53, one goes to rx / tx / cts / rts pins on the board, one is not connected.

    You can figure out which COM from your computer is connected to which VCOM on the DK through the command "nrfjprog --com". What appears as VCOM0 from the nrfjprog output, on the serial number for the respective DK, should be the one connected with the nRF53 on the board.
