I am trying to define a BOOTDEV variable, which is referenced another variable "BOOT_PARTITION", the code just shows as bellow: file: poky/build/conf/local.conf # Boot device Selection BOOTDEV = "${BOOT_PARTITION}" and, I will export BOOT_PARTITION=/dev/sda2, then run bitbake. But it seems that BOOTDEV still be empty.
Fixed by a hack way, close it now if no more comments.
