nrf connect sdk: thread tools: configuring a radio co-processor

[Jan_Erik]

On the nrf connect sdk documentation page there are instructions for configuring a radio co-processor:

http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thread_tools.html?highlight=srp

For the nrf52840dongle the build command is:

west build -p always -b nrf52840dongle_nrf52840 nrf/samples/openthread/coprocessor/ -- -DOVERLAY_CONFIG="overlay-rcp.conf ../cli/overlay-thread_1_2.conf overlay-usb.conf" -DDTC_OVERLAY_FILE="usb.overlay"

The command fails with the error 

cc1: fatal error: usb.overlay: No such file or directory

I can't find the file usb.overlay file anywhere in the ncs directory. 

Please provide the contents of the usb.overlay file.

Thanks,

Jan Erik

Hi Jan Erik,

Are you on the master branch since you are linking to the latest documentation? For the v1.7.1 release the command it's a bit different: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.7.1/nrf/ug_thread_tools.html#configuring-a-radio-co-processor

So make sure you are using the same NCS tag and documentation tag.

Best regards,

Marjeris

Hi Marjeris,

Thank you for your prompt and kindly worded reply. I was indeed using the 1.7.1 branch. I will be mindful of using the same NCS and documentations tags in the future.

Using the command from the 1.7.1 documentation tag, the co-processor builds on the nrf52840dongle as expected.

Best regards,

Jan Erik
