Linux/AM5748: DDR3 memory stress test software

Roger Newbould31

Part Number: AM5748

Tool/software: Linux

We would like to thoroughly test the DDR3L interface of our AM5748 board. We are running Linux.

There is "memtester" in Linux which writes/reads back several test patterns. Is there another tool which also takes timing parameters into account, meaning it adjusts certain parameters until there is an bit error so we get some kind of information regarding timing margin?

Is there also a tool to verify ECC functionality? Which prints out the value of related registers?

Thanks and best regards,

Roger

Roger,

Thanks for your post.

We use memtester quite extensively. I don't know of a tool that takes timing parameters into account for timing margin.

This post details our recommendations for testing ECC:

I hope this is helpful to you.
