Hi,
I had come across this link → HAB/AHAB Secure Boot on Colibri iMX8x - Technical Support - Toradex Community,
which says in Toradex, for HAB they are simply following the documented approach from NXP and do not have anything related with HAB/AHAB here at Toradex.
Also, I came across this link for Torizon OS.
Is there a reference link similar to above for Yocto Custom OS?
