UART Example Program not working when changing default uart pins

[Suresh Palani]

I have nrf52840-dk board.
i tried the UART example from the peripherals directory. it works with the default UART Configuration pins.

problem started when i tried to change the pins to p0.6 and p0.19. i didn't change anything else, just the pins numbers.

I am using Keil IDE with nRF5_SDK_17.0.2_d674dde.

And am using USB to TTL converter.

Hello,

If you take a look at the silkscreen on the backside of the board you can see that P0.19 is not connected to the pin header, but the QSPI flash module next to the nRF52840 IC. You may try pin P0.26 and P0.27 instead.

Best regards,
