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
