[email protected] undefined node label causes build to fail

Open NoPlanNomad opened this issue 3 months ago • 1 comments

When trying to build a config with mikoto 6.3.0 board selected the following error gets thrown.

devicetree error: /soc/uart@40002000: undefined node label 'uart0_default'

When building with the 7.2.0 revision this doesn't appear to be an issue.

Narrowed the problem down to just 6.3, I'm currently building with 6.1 which works. I'm not quite sure how the revisions work but the lack of a mikoto_6_3_0.overlay leads me to think that might be the problem.

I don't think we ever had support for 6.3. I assume that the definition for 6.3 is identical to 6.1 or something. @zhiayang can you confirm?

According to the yaml files for mikoto I did actually define a v6.3. I assumed that the zephyr build system would automatically pick up the 6_1_0 overlay, but I guess not. I never actually built/ordered a v6 mikoto so I never tested it (:

Will put up a PR to add the missing overlay soon.

@NoPlanNomad For now you can build with 6.1, there's no changes between 6.1 and 6.3 that require zmk/zephyr changes.
