Hi team,
Just for information, I am using the imx6q board and implementing the secure boot HAB and have tested the manual fused the public key
SRK_1_2_3=_4_fuse.bin
is this is working fine, but i want to automate this fusing using in the UUU script.
I have already the information about the HAB block in u-boot.imx.log file
$cat u-boot.imx.log
Image Type: Freescale IMX Boot Image
Image Ver: 2 (i.MX53/6/7 compatible)
Mode: DCD
Data Size: 602112 Bytes = 588.00 KiB = 0.57 MiB
Load Address: 877ff420
Entry Point: 87800000
HAB Blocks: 877ff400 00000000 0008ec00
DCD Blocks: 00910000 0000002c 000001c4
As per the UUU pdf " the IVT is modified when downloading to the target the binary must be signed with a cleared DCD pointer".
Do i have to use the mentioned script for generating the DCD pointer, /mod_4_mfgtool.sh for all images ? or How it works ?
Please give suggestion on this action.
Regards,
Rk
