WARNING: A print request was detected on not active shell backend. Error on Throughput example project

[sotillo2409]

Hi everyone,

I have a custom board based on nrf52840, the Fantsel BC840. I have created my custom board, changing assigment of pins for leds, buttons and UART0 on custom_board.dts

All work fine but i have the next issue... When i try to send a shell command using UART0 shell isn't react, and get this warning:

How i can active shell backend to fix this error???

Any help is welcome, regards.

Hi 

Have you been able to test this on a standard nRF52840DK, to see if this could be related to the custom board you are using?

If the problem is the same on the DK then it should be possible for me to reproduce it here. 

Best regards

Is closed... I change the Rx pin of UART to another one and is working fine, i don't understand but is okay.

Good to hear you found a solution, even if it doesn't explain why P1.01 doesn't work. 

Make sure to read the documentation of your module to see that this pin is not connected to anything else, and that the connection from the module to your board is OK. 

Best regards
