Our company has replaced 2GB JSC DDR for imx93x, which cannot be started normally. The error is as follows

U-Boot SPL 2023.04-myir+g06fd9d4467 (Dec 08 2023 - 03:50:09 +0000)
SOC: 0xa0009300
LC: 0x40010
Training FAILED
M33 prepare ok

Then I used the DDR test tool of imx tools to test the 1G test and failed the 2G test

Can you tell me how to solve it

Hello,

it would be difficult to know what is the issue here, I would recommend to check either the configuration for the second block or that the hardware for the 2 block have some issues.

Best regards,
Aldo.

Thank you. Currently I suspect it has something to do with the DDR ranks. The 93xevk and 1G models of our board are used in 1Ranks normally, but the DDR we replaced this time is 2 Ranks

I was able to successfully test 1GB when I ranked 1, but failed to test 32MB when I ranked 2.

 

I am not sure if it is my software configuration problem or the hardware does not support 2Ranks, can you tell me how to configure it

If there is still no progress, then I will replace 1 Ranks 2 G DDR for debugging.

At present, I can boot the system, and 2GDDR can be recognized normally in uboot and file system, but when I use memtester test, I can only request 500M, and 600M will report an error
