MPC562D: How to inject multiple-bit ECC Flash Data Error to verify implementation of ECC Flash Error Exception handler

Hello David,

I am using MPC5602D controller in my project and dealing with 2-bit Data-Flash-Error handling.

Query:

Could you please guide me for How to inject multiple-bit ECC Data-Flash Error and how to handle the Exception generated.

MPC5602D has DFLASH -> 32+7 implementation.

You can use the same patterns as described in chapter 6.2 of my document:

https://community.freescale.com/docs/DOC-103300

You may see example 5, function Generate_noncorrectable_FLASH_ECC_error in main module.

Although different device (MPC5675K), data flash uses same algorithm. However in other aspects it acts differently, exception handlers you could take from example 1.
