HAB secure boot issues

[angelo_d]

Dear all,

need some help, i am testing HAB in imx6q, loading u-boot, still getting several HAB events / errors from u-boot. Still working in "open" mode.

Have some questions:

1) How do i know what HAB version my chip supports ?

2) What is the most recent and updated document for HAB on imx6q ?

These document "http://www.google.it/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwj29dbMtNvKAh...   " is the correct one ?

3) What are the meanings of HAB events errors bytes ? I only see a stream of hex chars from u-boot as

-Boot > hab_status 
Secure boot disabled
HAB Configuration: 0x00, HAB State: 0x00
