Hello,

I want to know NCF[1] reporting of Ecc error.

The RM explains it like this, And I think the EDC bus gaskets can get the Ecc error.

NCF[2] is reporting of RAM Ecc and, NCF[3] is reporting of Flash memory Ecc. Right?

I think NCF[1] is reporting of Ecc error about some memory sector.. But i don't know exactly.

If you know about this part please reply.

NCF[1] are all EDC ckeckers as you can see for instance below. It is protection of transfers over various system busses.

That mean

If an Error occurs using EIM, you can detect Ecc Error by checking the EDC checking wdata. right?

However, i occured Sram Ecc Error without EIM.

So i think NCF[1] has anything to do with Ecc Error.

 

You mean you can still find out using EDC checking wdata?

I am afraid I don't understand you too much.

Every error that can be injected may also happen due to failure, either soft or hard.
