t4240 ddr validation target connections fail

t4240 custom board.

Now my board is stuck in the DDR initialization section, so I created a DDR project using

CodeWarrior, but CodeWarrior cannot connect to the DDR.

CodeWarrior Debug can connect, DDR verification is not,why?

Can you check my CW configuration for me

I want to know if my connection configuration is correct ?

When you click "Start Validation" the CCS(CodeWarrior Connection Sever) will be popped up at the right bottom of the Window task bar, please open CCS console, type "log v" then click "Start Validation" again, the low level CCS log will be printed in CCS console, please capture this CCS log to me to do more investigation.

My current problem is that the "Start Validation" is grayed out and I can't click on it

You use T4240 processor, why did you configure the "System" as T2080?

If your problem remains, please capture the CCS log to me to do more investigation.

I have two boards, a T2080RDB and a T4240 custom board.

t4240 custom boadr is discrete ddr.

No output is generated after the target connection.

this is my codewarrior. I don't know because something is wrong with the configuration ?

It seems that you didn't open the correct CCS console.

Please close CodeWarrior IDE and all CCS consoles.

Then open CodeWarrior IDE again, click Target Connection, the CCS console will be popped up automatically, please use this CCS console, type "log v" and connect to the target board again, the low level CCS log will be printed out.
