  • Hi,

    We want that flash memory of the code area should be locked after programming to avoid malicious attempts to read the code memory and steal the software after the chip is deployed. We want this for MPC5748C controller. Please guide how to achieve this.

  • Greetings,

    First, I want you to read the UTEST and DCF records portion of your device's reference manual. Once you do that, then go to Support page -> Support requests and create a ticket for me. I can send you files of how I would censor the device using the UTEST region.
