What are the .yaml files in the board folder used for?

[stes]

Dear devzone-team,

 could you please tell me where the yaml files (like thingy91_nrf9160_ns.yaml) in the board folders are used?

I could not find a tool which evaluates the settings found in this file:

identifier: thingy91_nrf9160_ns

name: THINGY91-nRF9160-Non-Secure

type: mcu

arch: arm

toolchain:

  - gnuarmemb

  - zephyr

ram: 128

flash: 256

supported:

  - i2c

Thanks

Stefan

Hey Stefan!

In the <board variant>.yaml, you can specify the properties for your board, such as toolchain, supported features, ram and flash size. It works as a device tree input file, much like the overlay file.

For more info about this, you can take a look at this overview on zephyr and part 3 of this NCS tutorial.

Best regards,

Elfving
