HAB Boot Signed Kernel: HAB Events

dheerajr — Wed, 14 Mar 2018 02:27:43 GMT

Hi, I am trying to implement secure boot. I have successfully signed U-boot and it's working fine. Now, I have generated IVT for Kernel and have signed the kernel image. However, upon executing this command from u-boot command line (hab_auth_img 82000000 54a020), I am getting HAB events. What do these HAB events mean, how to decipher these HAB events and what is the solution for 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 -----------------
event data:
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)

Regards,

Dheeraj
