The meaning of BOARD in Zephyr environment is pretty much equivalent to MACHINE in yocto environment. So the envisioned solution would look something like: $ MACHINE=arduino_101 bitbake zephyr-philosophers or $ MACHINE=qemu_cortex_m3 bitbake zephyr-philosophers etc. where, of course, MACHINE can be set in local.conf as well. 69696 2 juro.bystricky 2017-01-10 23:01:36 +0000 I created support for these new MACHINES: MACHINE=arduino-101 MACHINE=arduino-101-sss MACHINE=qemu-cortx-m3 (with more to follow) These correspond to Zephyr boards: BOARD=arduino_101 BOARD=arduino_101_sss BOARD=qemu_cortx_m3 Specifying MACHINE will implicitly determine cross-compiler toolchain as well. (There is 1:1 correspondence between Zephyr BOARD and Yocto MACHINE so a lookup table BOARD:MACHINE may be needed in the future, presently all that is required is to convert "-" to "_") 70045 3 juro.bystricky 2017-01-23 20:28:57 +0000 meta-zephyr: https://git.yoctoproject.org/cgit/cgit.cgi/meta-zephyr/commit/?id=7c3f7c10de57ae4f4add938fa5188095c5230a69
