imx93 lpddr4x ddr校验

[yrj]

您好  NXP

      请问我想使用JSL4BAG167ZAMF-05A这颗DDR，使用Config Tools for i.MX 25.06工具校验时，性能优化测试中，未出现绿色格子，无法下一步了

配置如下

请问哪里有需要修改的吗，修改DQ ODT and DS config 也是无法出现绿格子

我查看存储兼容是有这个型号的，麻烦帮忙指导下  谢谢

Hello,

Could you please share the log?

The configuration is correct but it seems that the issue is caused by integrity issues?

Did you verify the DDR layout?

Best regards.

HI @JorgeCas 

    我将配置改为3200Mbps，就可以了，但是烧写文件系统中，内核出错，uboot或者内核地址有需要修改的地方吗

Hello,

Some of the LPDDR4/4X devices may not support operation at low speeds.

For Windows try to open the PowerShell with administrator permissions.
 
If the problem persists, try to delete and download the latest UUU tool again.
 
Another cause can be the USB cable or the host computer, try changing the cable and the host computer if needed.

Best regards.

HI @JorgeCas 

    我这一颗JSL4BAG167ZAMF-05A 单颗密度是8G       8G  x  2rank   x16 Row Addresses

我看官方说是支持的，需要哪里有特别的设置吗

DDR校验工具的配置已经改为如下，可以烧录进去，但是使用memtest失败

双列 LPDDR4x需要特别设置吗

Hello,

There is no need of additional changes.

As you can see in our DDR Tool, there are different available configurations for DDR memories, if the configuration of your memory cannot be entered into the tool, the memory cannot be tested or the script cannot be created, please confirm that is not the case since the tools is "hard coded" to those options and we do not have a guide to configure the script manually.

Best regards.
