Can the core board be used without a carrier? such operation would be impractical at least, that's why in my v1 Core board didn't have its own compatible. Maybe I didn't understand you correctly. Shall I drop the above 4 lines, the compatible property from the root in sun50i-a133-baije-core.dtsi and only leave sun50i-a133-baijie-helper.dtb with 3-strings compatible as it is now in v2? --=20 Alexander Sverdlin.
