Uses nrf_log_info() in sparkfun breakout pcb

[DavidC]

Hello community,

Before I was using a pca10040 by Nordic evaluation board. The project, that i developed, is running well using the EB but when I change to sparkfun breakout pcb I cant use the rtt(becuase i dont uses a Segger programm in the pcb) but instead i use

NRF_LOG_ENABLED 1 
NRF_LOG_BACKEND_SERIAL_USES_UART 1

After flashing the programm i cannot read any display on the terminal.

What else I need to activate ?

I think you can use the JLink OB in your PCA10040 to "talk" to the sparkfun breakout board and thus use RTT for your tracing; try to connect the SWDIO and SWDCLK from the debugout of your PCA10040 to the corresponding SWD lines in the sparkfun breakout board and see if that works.
