Hi, I am implementing secure boot for imx6sx sabresd board. I have generated an IVT table for kernel and have signed the kernel image. However, once i execute this command in u-boot (hab_auth_img 82000000 54a020), these HAB events show up. May I know what this HAB events mean, how to understand these events and how to overcome this problem?
=> hab_auth_img 82000000 54a020
Authenticate image from DDR location 0x82000000...
Secure boot enabled
HAB Configuration: 0xcc, HAB State: 0x99
--------- HAB Event 1 -----------------
0xdb 0x00 0x08 0x41 0x33 0x05 0x0a 0x00
STS = HAB_FAILURE (0x33)
RSN = HAB_INV_IVT (0x05)
CTX = HAB_CTX_AUTHENTICATE (0x0A)
ENG = HAB_ENG_ANY (0x00)
