Several times, different people and different build hosts, we have failed to successfully follow the instructions presented on this page:
always the opencv portion fails with the error:

I was able to get around, finally, by commenting out the line
PACKAGECONFIG_append_mx8 = " opencv kms tinycompress"
from the file
but I'm curious as to how the initial/default firmware image was created
(i.e. the ones available here: https://ftp1.digi.com/support/digiembeddedyocto/3.0/r3/images/ccimx8x-sbc-pro-installer.zip)
