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

Mahendra Tailor

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.
