How to building the openthread\coprocessor project on the nrf52840_dongle?

Dear Nordic Engineers

I use the NCS V1.9.1.I would like to building the  openthread\coprocessor project on the nrf52840_dongle.I read this page:https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/nrf/samples/openthread/coprocessor/README.html.

The coprocessor sample support the nrf 52840 dongle.

But an error occurred during the construction of the project.

I try to create a new .overlay file.But look like it's useless.

Please help me,how to building the openthread\coprocessor project on the nrf52840_dongle?

Best regards.

  • Hi,

    The nRF52840 Dongle does not have UART, so you must configure the sample to use USB instead by setting OVERLAY_CONFIG to overlay-usb.conf and DTC_OVERLAY_FILE to usb.overlay as described in Configuration files. You cannot specify multiple CMake options in SES due to a bug, so you will have to use VS Code or command line to build the sample. 

    Best regards,
