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 ?

Regards, David Caraveo

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.

I'll try it, thanks

I am using both the Sparkfun nrF52832 breakout and pca10040. I connected SWD protocol as described in the nRF52832 Breakout Board Hookup Guide. With the SWD connection you can use SEGGER RTT via the pca10040 board.
