devicetree undefined node

[naive rover]

Hi, I'm having a devicetree error with initial setup for Jiran keyboard. I've followed the standard steps as per user guide with no changes to keymap. The error reads as:

-- Found toolchain: zephyr 0.15.2 (/opt/zephyr-sdk-0.15.2)
-- Found BOARD.dts: /__w/zmk-config/zmk-config/zmk/app/boards/arm/nrf52840_m2/nrf52840_m2.dts

devicetree error: /kscan: undefined node label 'pro_micro'

What am I doing wrong?

Jiran uses Pro Micro footprint.

You need a board compatible with Pro Micro.

Hi @shadow edge . Thanks for the answer! It's now getting clearer what the problem is. Mine was built with nrf52840 m2. Not sure if it's compatible. As far as I understand I'll have to modify the ZMK firmware code to compile for this board. Am I correct?

You can add a new shield to your zmk-config repo.

I don't think m2 interconnects are abstracted out like &pro_micro, so you'd likely need to rewrite the shield definition to directly use nRF pin numbers, like P1.01 would be &gpio1 1 and P0.20 would be &gpio0 20, etc.
