Yocto MACHINE target?

[zener]

Did anybody have any success building Yocto for the RockPro64?

I also tried this recipe

http://rockchip.wikidot.com/yocto-user-guide

Code:

MACHINE=excavator-rk3399 DISTRO=rk-x11 . ./setup-environment -b my-build

but then

Code:

bitbake core-image-base

results in
