RF Test on custom board (nrf5340 + nrf21540)

[benoit.gorostidi]

Hello,

I create a custom board based on nRF5340 with a FEM nRF21540 and I would like to test radio part with some fixed frequency test.

It seems that SDK (nrf connect 2.4) provides a sample for RF test (Direct Test Mode).

After adding my board in the "Direct Test Mode" project, I meet some build error:

My custom board has an UART0  (only TX) for debug and USB capability.

Hi,

It looks like your custom board does not define the DOMAIN_CPUAPP_BOARD symbol. Please try adding it to the Kconfig file in your board directory like how we've done it for the nRF5340DK here: https://github.com/nrfconnect/sdk-zephyr/blob/c7094146b5b47fd4da05ed773e0128e2e6a634e1/boards/arm/nrf5340dk_nrf5340/Kconfig#L51. Note that the string should reflect the name of your board. 

Best regards,

Vidar

Hi,

I've double checked the Kconfig and the DOMAIN_CPUAPP_BOARD is well defined with the board name.

[Vidar Berg]

Hi,

Please check what the DOMAIN_CPUAPP_BOARD symbol is set to in your .config output file.

[benoit.gorostidi]

Actualy, DOMAIN_CPUAPP_BOARD symbol is not taken into account in the .config file.
