Issue : Build Error for OpenThread Coprocessor Application

[swapnilcchougule]

Discussed in https://github.com/zephyrproject-rtos/zephyr/discussions/75279

^{Originally posted by **swapnilcchougule** July 1, 2024} Hello, I am trying to build the OpenThread coprocessor application using the following command: west build -b efr32xg24_dk2601b zephyr/samples/net/openthread/coprocessor However, I encounter the following error during the build process: zephyrproject/zephyr/include/zephyr/device.h:89:41: error: '__device_dts_ord_DT_CHOSEN_zephyr_ieee802154_ORD' undeclared here (not in a function) Additionally, it appears that **Silicon Labs has not provided any bindings for the IEEE 802.15.4 node**, which might be contributing to the issue. Any guidance on resolving this issue would be greatly appreciated. Thank you! Regards, Swapnil

Hello,

I'm following up to check if there are any updates regarding my previous post about the issue with building the OpenThread coprocessor application on the EFR32MG24 platform.

I would greatly appreciate any feedback from silicon labs team.

Thank you! Regards, Swapnil

Hello @swapnilcchougule,

Indeed, Silabs SoCs have no 802.15.4 drivers for Zephyr. That said, this is definitely doable using CONFIG_SOC_GECKO_USE_RAIL and the RAIL API.

I think the Silabs support could help you on that topic. We would be very happy to merge this contribution in Zephyr.
