Rather than building images and then testing them with a BuildImage step followed by a RunSanityTests we might save some effort by folding the two into one step. i.e. bitbake core-image-sato:testimage instead of bitbake core-image-sato && bitbake core-image-sato:testimage This would require inheriting testimage-auto, rather than testimage, and would also likely require enhancements for SDK testing that would need backporting.
Resolved by the new infrastructure architecture of helper scripts (yocto-autobuilder-helper) with a more recent buildbot with minimal configuration (yocto-autobuilder2).
