The link mentions the procedure to build SDK images for HS devices , also prerequisite says J6 HS EVM revisions G or H, or J6 ECO HS EVM revisions B or C is required.
will this procedure work for j6- DRA746 SOC .

OP-TEE is only supported on the HS versions of the DRA7 device silicon. If you do not have a secure (HS) part (which is the type of device that you would find on a HS EVM), you will not be able to use or follow those directions. A general purpose (GP) DRA746 part cannot support the use of OP-TEE as described in the original link provided.
