Hello,
We are trying to use the HAB feature of the iMX280 processor. We have fused the SRK hash in the OTP fuses, but when trying to boot our signed images, we get the following HAB events:
--- HAB Event 1 ---
0000 : DB 00 14 40 33 2D C0 00 BE 00 0C 02 09 00 00 01 : ...@3-..........
0010 : 00 00 02 5C : ...\
--- HAB Event 2 ---
0000 : DB 00 14 40 33 0C A0 00 00 00 00 00 00 00 00 14 : ...@3...........
0010 : 00 00 00 20 : ...
--- HAB Event 3 ---
0000 : DB 00 14 40 33 0C A0 00 00 00 00 00 00 00 0C 38 : ...@3..........8
0010 : 00 00 00 04 : ....
--- HAB Event 4 ---
0000 : DB 00 14 40 33 2D C0 00 BE 00 0C 02 09 00 00 01 : ...@3-..........
0010 : 00 00 02 5C : ...\
--- HAB Event 5 ---
0000 : DB 00 14 40 33 0C A0 00 00 00 00 00 00 00 1E A8 : ...@3...........
0010 : 00 00 00 20 : ...
--- HAB Event 6 ---
0000 : DB 00 14 40 33 0C A0 00 00 00 00 00 00 00 1B 2C : ...@3..........,
0010 : 00 00 00 04 : ....
--- HAB Event 7 ---
0000 : DB 00 14 40 33 2D C0 00 BE 00 0C 02 09 00 00 01 : ...@3-..........
0010 : 00 00 02 5C : ...\
--- HAB Event 8 ---
0000 : DB 00 14 40 33 0C A0 00 00 00 00 00 41 03 86 08 : ...@3.......A...
0010 : 00 00 00 20 : ...
--- HAB Event 9 ---
0000 : DB 00 14 40 33 0C A0 00 00 00 00 00 41 00 80 00 : ...@3.......A...
0010 : 00 00 00 04 : ....
As far as we can understand it, event 1, 4 & 7 indicate a HAB_OVR_STORAGE error.
The other events indicate a HAB_INV_ASSERTION for ivt & image entry for respectively power_prep, boot_prep and u-boot, which we suspect is a consequence of event 1,4 & 7.
Does anyone know what event 1,4 & 7 mean exactly since we couldn't find a description of those anywhere ?
Many Thanks,
Filip Aben
