Original question:

Linux/AM5748: DDR3 memory stress test software

Linux/AM5748: Test of asynchronous memory

Tool/software: Linux

Hi

I have another question related to memory testing. For testing the DDR3 memory we use memtester under Linux.

In our design we have also connected asynchronous SRAM and MRAM to the GPMC block of the Sitara. Can memtester also be used to test these types of memory devices? Or is memtester only usable for DDR3? Or do you use a different tool to test asynchronous memory?

Thanks and regards,

Roger

    Roger,

    We don't have much async memory on our boards, so we don't have a lot of experience with testing them. Looking at memtester a bit, I don't see any reason it wouldn't be a good solution.

    Maybe someone else from the community has more experience and can offer their insights.

    Thanks for the post.

    I've always run memtester by just specifying an amount of memory, e.g. "memtester 1M" would test 1MB of memory, and the memory gets allocated out of the Linux system memory. I see however that there's an option where you can specify the physical address of the memory to be tested. I expect that should be usable for async SRAM. Like Ron, I've not tried it out personally, but it looks feasible.
