I will report it to our documentation team. Thank you for reporting!

Best regards,

OK, that appears to have fixed the problem,

though its not obvious to me why that would would be the fix to that warning.

i think it might be worth adding a note to that sample that the usb.overlay is required for the dongle

Oh, ok. I see.

Looking at the sample description, it says under the "Configuration files" section what you need to do if you want to enable serial port over USB, which is something that we need to do if we are using the dongle, because unlike the DK, the UART is not carried through the USB port (because it is using the nRF's USB instead of the programmer's USB).

So when you create your build configuration, you should set the overlay-usb.conf as a Kconfig fragment (remember to click OK after selecting it, so that it is actually included). You also need to set the DTC_OVERLAY_FILE to usb.overlay. The way you do this is by adding this as an extra CMake argument:

-DDTC_OVERLAY_FILE=usb.overlay

(again, click OK to save that CMake argument).

It should look like this before you hit "Build Configuration":

Try that, and let me know if it doesn't work.

Best regards,

should be default build configuration generated by Code Studio

I opened Code studio then nrf Connect
clicked "create a new application"
selected "samples/openthread/coprocessor" template
set name
then create application

clicked "no build configuration"
set board to "nrf52840dongle_nrf52840" and click build configuration

which gives 5 problems

can fix

CONFIG_LOG_PROCESS_THREAD_STACK_SIZE couldn't be set. Missing dependencies:
LOG_PROCESS_THREAD && LOG_MODE_DEFERRED && LOG

automatically by clicking "enable three entries to to resolve dependencies"

i can see SHIELD_SPARKFUN_SARA_R4 but haven't set it anywhere and
isn't user assignable according to kernel docs and is disabled by default

so do don't know how or why its there or how to disable it

current proj.conf

as there is nothing special in it i have also put the generated code on github https://github.com/ctyerman/nrf52840dongle_coprocessor_test

after some further research this might be related to issue 25480 but still not sure how to fix it

Hello,

What exactly are you trying to build? Is there any way for me to reproduce the build error you are seeing? What is your build configuration?

It looks like you have tried to include sparkfun_sara_r4 at some point. It looks like it is a shield, but where and how did you include it?

BR,
Edvin
