How to understand the corruption of code loaded to MPC5777C

[berat24]

Hello everyone,

I have a question. Could you inform me about whether there is a way to understand the corruption of code loaded to MPC5777C?

Shall be the steps as following? 1. Build application 2. Calculate MISR signatures on host 3. Load calculated signature with linker to a flash adddress ADR_A . 4. Use array integrity self check to verify application code signature with ADR_A.

Good works.

Hi,

take a look at these two examples:

https://community.nxp.com/t5/MPC5xxx-Knowledge-Base/Example-MPC5744P-FlashArrayIntegrityCheck-test-S...

It shows step by step how to calculate MISR values by offline tools and how to run Flash Array Integrity Check on the MCU.
