MPC5746C Flash Initialization Error

Hi,

 

Every time the processor boots up, I get an RGM.DES.B.F_SWT0.RES = 1.

This means that there is/was a Flash Initialization Failure.

I am trying to investigate the problem further.

My problem is that the failure is kind of vague. I don't know what it means exactly.

I am wondering if it is trying to initialize a certain block?

Is there some sort of read/write error?

Would it be in the Initialization script 57xx_flash.ld?

I have seen code out there that does a flash check. It is written for another processor.

Perhaps I could modify it to check the flash on the MPC5746C?

 

Thank you,
