NXP DDR Test Tool

Arm7 — Wed, 09 Aug 2023 22:34:32 GMT

Hello,

Can I run this program in multiple instances on a single PC to run multiple boards ?

I have different boards and would like to run them but on a single PC.

It is possible ?

How ?

Thank you for you support!

Hello, I hope you are doing well.

That feature is not in the documentation but, let me check.

Right now, I do not have access to the boards until the next Monday.

I will check with two boards (using the same processor and different processors) and I will let you know as soon as possible.

Best regards.

Hello,

I was able to run both tests at the same time with the tool for i.MX8M.

But, it the case of i.MX6/7 tool, when is connected more than one board, it occurs an error.

Best regards.

Hello, Thank you!

What about Virtual Machines, Can we run multiple virtual machines on one PC to test more boards ?

Hello,

In that case it is needed to check it, there is no information to run this tool on a VM.

Best regards.

This tool is not a production test tool, it is intended to be used during the prototype phase to verify the PCB design and validate the software parameters for the DDR memory in use. In the final test of an end product you should use something like Linux memtester to verify to correct functionality of your product.

Hello @bernhardfink

Where can I find the source or binary of the memtest ?

Hi @Arm7 ,

it's "memtester" and it is open source.

https://linux.die.net/man/8/memtester

You can easily compile it for your i.MX platform in case it is not part of your BSP anyway.

$ bitbake memtester

The resulting packages (the default format is rpm) can be found inside build/tmp/deploy/rpm.

There would be an alternative to the GUI tool running on the PC. You can include a test firmware into u-boot and run it from u-boot level. Then you would have it on each board and there would be no need to load and run it from the PC.
