DDR validation tool: can connect with board but can not pass validation

carlpeng — Tue, 18 Jul 2017 03:20:38 GMT

Hello,

Could you please help to give some suggestions?

There are two kinds of phenomenons:

1st: can connect with board, but can not pass validation

When I use DDR validation tools to get DDR configuration paras, DDR validation tools can connect with board, but can not pass validation, its color is orange, as the below figure show:

And will pop the below error：

2nd: during validation, board will continuously reboot and execute uboot

Why will execute uboot during validation?

In my opinion, after codewarrior connecting with board, codewarrior should control the board, and send instructs to

board rather than let CPU to execute uboot, are there any issues?

Thank you!

Carl

1. This means initial configuration is not ok. You need to start from a configuration accepted by DDR controller. Since you have a running uboot, you can import DDR configuration from there.

2. Not DDRv executing the uboot, just reset the board for applying the DDR configuration and you can see uboot restarting.

Hello Adrian,

Thanks a lot for your response!

1. This means initial configuration is not ok. You need to start from a configuration accepted by DDR controller. Since you have a running uboot, you can import DDR configuration from there.

Do you mean that some parameters of DDR validation project are not set rightly as the below figure shows?

Thank you!

Yes, you need to set the params according with your DDR module.
