Eliminating trace functionality during debug

[Daniel Reisfeld]

Hi,

I'm using custom board with the nrf42840 and I need to use p1.09 as a GPIO. 

How can I do this in a debugging mode (using the PCA10056 as a jlink)? Can I get a code example? 

Thanks,

Daniel

Hi Daniel

The TRACE pins should work as GPIOs in debug mode by default in our examples. Have you tested this before making any changes? When setting the TRACEMUX to 0, you should only set bits 16 and 17. The rest of the TRACECONFIG register should be left as is.

Best regards,

Simon
