No printouts for cli_libuarte with make and nrfjprog

[Hedvig]

Hi, I am trying to create a project using make in addition to my SES project. My problem is that I see no printouts on /dev/ttyACM0 (using minicom to debug this), but I do when I use SES. To debug this I created a Makefile from example SES project cli_libuarte, but still no luck.

My setup is an nrf52840 devkit, SDK5 v16.0.0 and softdevice 7.0.1, and main.c and sdk_config.h from cli_libuarte example, no changes.

In the Makefile I use nrfjprog to program my device like this:

nrfjprog --eraseall --snr $(JLINK_ID)
nrfjprog --program ../../sdk/components/softdevice/s140/hex/s140_nrf52_7.0.1_softdevice.hex --snr $(JLINK_ID)
nrfjprog --program _build/nrf52840_xxaa.hex --snr $(JLINK_ID) --sectorerase
nrfjprog --reset --snr $(JLINK_ID)

The project builds and is uploaded, but I see no printouts.

What am I missing?

Hi,

To debug this I created a Makefile from example SES project cli_libuarte

Why did you not use the makefile in examples\peripheral\cli_libuarte\pca10056\blank\armgcc, which already exists? Or did you want to compile with SES, but using a makefile to automate it and run from command line?

I do not think this is related to the flash process, it looks correct.

Best regards,
Jørgen

Thank you! I had missed that there was an example Makefile to look at. This solved my problem.
