error: '__device_dts_ord_26' undeclared

[kaushalyasat]

Hi,

I am just starting to develop a nRF5340 based prototype. I am using the openthread CLI example as the first step. I have configured the device tree to suit our board in a new overlay file. I dont see any issues from device tree visualizer. But when I try to build the example, I get 'error: '__device_dts_ord_26' undeclared' from /zephyr/modules/hal_nordic/nrf_802154/serialization/platform/nrf_802154_spinel_backend_ipc.c: In function 'nrf_802154_backend_init': I am using SDK 2.6.0.

What is going wrong here?

Cheers,

Kaushalya

Hi Kaushalya,

It looks only device used in nrf_802154_backend_init is nordic_802154_spinel_ipc.

const struct device *const ipc_instance =

        DEVICE_DT_GET(DT_CHOSEN(nordic_802154_spinel_ipc));

    int err;

The nRF5340 Interprocessor Communication (IPC) is a peripheral used to send and receive events between Microcontrollers (MCUs) in the system. Each MCU has a dedicated IPC peripheral that can be used to send and receive events to and from other IPC peripherals.

Do you build the original OpenThread CLI example? Could you compared the both nrf\samples\openthread\cli\build\zephyr\.config and zephyr\samples\hello_world\build_nrf52840\zephyr\zephyr.dts to find the difference?

Best regards,

Charlie

Thanks Charlie.

When I try to build the original cli example, I picked up the board as 'nRF5340dk_nRF5340_cpuapp_ns. Then the original project build without errors. Then I changed the board to same in my project and add a blank overlay. I added just the minimum nodes I need and it build successfully. 

Now I am trying to flash the binary. But it fails saying the following.

I am using my nRF52840DK to program. I am using SWD interface and a reset from DK. The same interface I was using to program my nRF52840 boards.

You should use nRF5340DK or nRF91xxDK which has newer version of J-Link OB that support Cortext-M33 chips.
