AM2732-Q1: How to implement OTFA/OTFE (On-The-Fly Authentication/On-The-Fly-Encryption) on AM27x to ensure the security of XIP (eXecute-In-Place) in extended flash?

Hi team,the application image in the external flash is too large to be directly copied into RAM for execution, so the XIP(eXecute-In-Place) method is used to fetch instructions. The problem is how to ensure the authenticity, integrity and confidentiality of the application image when the chip is loaded and running in the external flash?

Thanks.
