Verify BR2_ROOTFS_OVERLAY value #5

Closed tpetazzoni closed 2 years ago

tpetazzoni commented 2 years ago

st_stm32mp157c_dk2_defconfig has BR2_ROOTFS_OVERLAY="board/stmicroelectronics/stm32mp157c-dk2/overlay/" which looks suspicious, as it doesn't use $(BR2_EXTERNAL_ST_PATH)

kmaincent commented 2 years ago

Only demos defconfigs use the overlay from $(BR2_EXTERNAL_ST_PATH). They need overlay to use a different extlinux.conf, indeed they use special devicetree from STM32CubeMX, which have a different naming (stm32mp157c-dk2-mx.dtb).

So the non-demo defconfigs, they use the overlay from upstream Buildroot, that's the idea ?
