iMX6UL HAB Questions

[SJA]

Can the signed u-boot image be verified on the EVK without CLOSING the SoC

when loading via USB (mfgtools technique)? When attempting this I

consistently see HAB events with INV_ADDRESS CTX_AUTHENTICATION.

Does the binary CSF file created using the cst tool have to be padded to the

size specified with CONFIG_CSF_SIZE in the u-boot imximage.cfg file before

being appended to the u-boot image?

Does the signed u-boot image need to be padded for 0x1000 alignment?

If so, does the size value specified in the CSF script "[Authenticate Data]

Block =" command reflect the u-boot image size before or after padding?

Note: We are using the HAB4 CSF Fast Authentication loading the images via

USB
