Hello,

We're planning to enable ECC in our system. (It's currently not enabled)

 

Wanted to understand more about the ERR_DETECT register in MPC8555's DDR Controller.

The spec states about 3 types of errors.

  1. multiple memory errors
  2. single and multi-bit ECC errors
  3. memory select errors.

 

Wanted to know the difference between the three.

Also, does this error imply a difference between the value in cache and RAM?

Or actual corruption in RAM?

 

Thanks

Dijo
