If I use Engine = SW, I see this result:

If I use Engine = ANY, then I get both HAB_INV_ASSERTION and HAB_INV_SIGNATURE.

I tried to follow HAB for Dummies.  https://boundarydevices.com/high-assurance-boot-hab-dummies/ 

Here are the first two errors:

I found out that for the i.MX6 ULL you must use Engine = SW.

 

Also, I was trying to use shadow registers (because of limited early board supply), but apparently they are ignored.
