No this is not the file I need. Please zip the whole working directory with your sample and attach it.

Hi Heidi,

I do not see a file named ".config" in the <build_folder>/zephyr directory. However, there is a filed named "Kconfig.zephyr" is this the file you are interested in? I am attaching the "Kconfig.zephyr" file to this email for the computer that compiles but does not run code on the nRF9160.

Also, to double check my steps when I Build and Run code: In the Segger Embedded Studio, I am selecting 1. Build> Build Solution, 2. Target > Download zephyr/merged.hex. Is this correct?

Kconfig.zephyr file from non-functional computer:

I think I need to take a look at the resulting build configurations since this seems to be a dependency issue.

Can you find the file <build_folder>/zephyr/.config when compiling with the computer where the resulting build is able to print to serial, and the file when the resulting build is not and attach them? Please attach files, and not screenshots.

Best regards,

Heidi

Here is a screenshot of my prj.conf file.

Hi!

Yes, there are settings to enable/disable serial output. Could you provide the prj.conf file of the application you are flashing and I will take a look.

The Zephyr Logging API provides numerous backends so it's easier for me to just take a look at what configurations you have currently enabled.

Best regards,

Heidi
