LS1026, DDR4 validation, read SPD data lost

rudolfusselmann — Wed, 24 Jan 2024 08:59:30 GMT

Hello,

we have a custom board with an LS1046A and a DDR4 DIMM module.

I have extensively read the QCVS_DDR_User_Guide.pdf.

When I start QCVS and create a new QorIQ DDR validation project, I have the option to read the SPD. After I read the SPD, I get the green check mark. I go ahead and click FINISH.

Now when I go to the Component Explorer, and look at the DDR properties, I click on "SPD Data" and then on the "..." Now, I expect to see the SPD data, but it is not populated (I get two empty boxes). I do see a file "ddr_spd.properties" in the project folder, and when I open it, it appears to contain the SPD data in XML format. Lots and lots data in that file ...

I have followed all the steps as outlined in QCVS_DDR_User_Guide section 1.1.4.1, pages 22-25, but do not get the same behavior.

I am running Ubuntu 22.04, in case that matters.

Any pointers appreciated !

Many Thanks,

rudi

Please refer to my following screenshot captured when connecting CodeWarrior to LS1046ARDB.

Do you have LS1046ARDB? If yes, please connect your CodeWarrior to LS1046ARDB to do verification.

Thank you for your message Yiping !

I am following these same steps as you are in your picture, but I do not understand how to make the SPD data move up.

Please see my attachment.

Many Thanks !

Please check whether you can continue to do validation in QCVS DDRv tool.

Yes, I can continue, and we do get optimal settings.

I am wondering why the tool does not work for me as it supposed to ?
