HAB Events on i.MX8Mini

[jbhaijy]

Hi,

I am getting HAB events on i.MX8Mini while booting on the OPEN SOM. I am signing SPL, u-boot-FIT & Kernel. 

- How can we authenticate each image separately from u-boot cmdline? 

- Can some please help me to understand the events logs? 

hab fuse not enabled

Authenticate image from DDR location 0x4a000000...

Secure boot disabled

HAB Configuration: 0xf0, HAB State: 0x66
