1. Please configure the target board as hard-coded RCW.

2. Use CodeWarrior to connect to the target board to program valid RCW on IFC NOR flash.

You need to customize RCW file according to your custom board.

Please refer to the following document to program RCW.

3. Configure the switch setting to boot RCW from IFC NOR flash and connect to the target board to do DDR validation.

If your problem persists, please capture CCS console log to me to do investigation.

In CodeWarrior IDE, while connecting to the target board, CodeWarrior Connection Sever(CCS) will pop up at the right bottom of the Windows task bar automatically, please double click and open it, then type "log v" and connect to the target again, the low level CCS log will be printed in the console, please capture the whole CCS log to me to do more investigation.

Dear yipingwang,

Thank you for your response

The procedure you have given is with nor flash,
currently we are using sram to boot rcw and validate the ddr
is that not possible ?
do we need to use nor flash ?

Yes, you need to deploy RCW binary at the beginning of NOR flash, then boot from NOR flash and do DDR validation with QCVS DDRv tool.
