Please look at my comments below.

According to the Appendix A (Interpreting HAB Event Data from Report_Event() API)

of the “HAB4_API.pdf” in the CST package, CAAM and SNVS engine failure takes place.

http://www.freescale.com/webapp/Download?colCode=IMX_CST_TOOL&appType=license&location=null&Parent_nodeId=13376994810717…

Summary Page :i.MX 6 Series Software and Development Tool R|Freescale

event data:

tag: 0xdb (HAB_TAG_EVT)

sts: 0x33 (HAB_FAILURE)

rsn: 0x28 (HAB_INV_CALL) Function called out of sequence

rsn: 0x22 (HAB_INV_ADDRESS) Invalid address: access denied

rsn: 0xc (HAB_INV_ASSERTION) Invalid assertion

If the reason of a HAB event is HAB_INV_ADDRESS (0x22)

[Invalid address: access denied] - please check if initialization

via DCD table meet allowed addresses.

Please take a look at Table 8-37 (Valid DCD Address Ranges) of the

i.MX6 DQ Reference Manual.

For the case 0xc (HAB_INV_ASSERTION) – the HAB checks that all of the

following data have been authenticated (using their final locations):

- IVT ;

- DCD (if provided);

- Boot Data (initial byte if provided);

- Entry point (initial word).

Each of the above data components not covered by a valid signature will cause HAB

to generate an event with reason HAB_INV_ASSERTION.

The SRK must be burned. Please look at section 18 (Burn the chip fuse to enable HAB boot)

of the “i.MX_6_Linux_High_Assurance_Boot_(HAB)_User's_Guide.pdf”.

Note, the SRK is only once burned.

Have a great day,
Yuri
