NRF5340 (Raytac MDBT53-DB-40) IPC_RADIO configuration error

[Patrick]

Hello,

I am currently working with the Matter lightbulb example in NCS v2.9.0 with the nrf5340 (Raytac MDBT53-DB-40). I have gone through the project tree and added overlay and config files based on the nrf5340dk overlays and configs in an effort to use this example on the aforementioned board. When building the configuration for the board, once I get to the ipc_radio step, I fail with the following error:

warning: NRF_802154_RADIO_DRIVER (defined at modules/hal_nordic/Kconfig:21, modules/hal_nordic/Kconfig:21) has direct dependencies (HAS_HW_NRF_RADIO_IEEE802154 && !y && HAS_NORDIC_DRIVERS) || (HAS_HW_NRF_RADIO_IEEE802154 && !y && HAS_NORDIC_DRIVERS && 0) with value n, but is currently being y-selected by the following symbols:
 - NRF_802154_SER_RADIO (defined at modules/hal_nordic/Kconfig:96, modules/hal_nordic/Kconfig:96), with value y, direct dependencies (HAS_HW_NRF_RADIO_IEEE802154 && !IEEE802154_NRF5 && HAS_NORDIC_DRIVERS) || (HAS_HW_NRF_RADIO_IEEE802154 && !IEEE802154_NRF5 && HAS_NORDIC_DRIVERS && 0) (value: y), and select condition HAS_HW_NRF_RADIO_IEEE802154 && !IEEE802154_NRF5 && HAS_NORDIC_DRIVERS (value: y)

I have compared the nrf5340dk and mdbt53-db board files and created overlays for a couple missing DT chosen nodes, but have been unable to determine why I ipc_radio fails. The project files have been attached to this thread for reference. The project does build for the nrf53dk, so I've apparently missed something. Any pointers in the right direction are much appreciated.matter_light_switch.zip

Hi,

This error is typical for missing this line in the board DTS

https://github.com/nrfconnect/sdk-zephyr/blob/7f8d857bf1f57b07e832d52263beaa23c91fef24/boards/nordic/nrf5340dk/nrf5340_cpuapp_common.dtsi#L20

I had added that node to raytac_mdbt53_db_40_nrf5340_cpunet.overlay, located in the sysbuild/ipc_radio/boards directory and that node is also present in raytac_mdbt53_db_40_nrf5340_cpuapp_common.dts. 

Based on the attached zephyr.dts (build/ipc_radio/zephyr.dts), the overlay is adding the missing zephyr,ieee802154 node, and while in a different order, the same as the zephyr.dts created when building for the nrf5340dk.

I see now that the message says:

"(HAS_HW_NRF_RADIO_IEEE802154 && !y && HAS_NORDIC_DRIVERS"

So the question is "what is y?"

From the definition of the Kconfig value, I see that it has:

" depends on !$(dt_nodelabel_enabled,timer1) "

It seems you are using timer1 for something else. Try to disable timer1 and try again.

Thanks for the assist Sigurd, disabling timer1 was the solution. For future reference, how did you connect 'y' to 'depends on !$(dt_nodelabel_enabled,timer1)'?
