Hi，
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Is it possible to temporarily disable encryption such that we could jump to a different region of NOR flash and execute unencrypted (plaintext) code?
-- After the ENCRYPT_XIP_EN fuse bit is blown, the ROM will boot the encrypted XiP image via the OTFAD, however, OTFAD allows the developers to set up 4 encrypted code areas into the application image, so the application image contains some plain code.
Hope this is clear.
Have a great day,
TIC
