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:

Executing task: nRF Connect: Generate config erl_nrf5340_cpunet for /home/bgorostidi/Workspace/Projects/Iot/nrf53_test/direct_test_mode

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

Best regards.

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.

Kconfig content:

	  This option enables releasing the Network 'force off' signal, which
	  as a consequence will power up the Network MCU during system boot.
	  Additionally, the option allocates GPIO pins that will be used by UARTE
	  of the Network MCU.
	  Note: GPIO pin allocation can only be configured by the secure Application
	  MCU firmware, so when this option is used with the non-secure version of
	  the board, the application needs to take into consideration, that the
	  secure firmware image must already have configured GPIO allocation for the
	  Network MCU.

Can you upload your .config file here?

[benoit.gorostidi]

You can found it in the zip file uploaded in my first message. Let me know if you cannot access to the file.
