Hi NXP Team
We have coustom build LS2088A board, in which CPLD is bypassed, but at the time we want to DDR SPD read from CW tap we are facing issue.
Can you please let us know the reset sequence to be followed at this DDR SPD read from CW TAP operation.
Hello Prashant Soni,
Would you please capture CCS log to me to do more investigation?
When you click "Read SPD", CodeWarrior Connection Server console will be open automatically, please type "log v" in the CCS console, then click Read SPD again, the low level communication log will be captured in CCS console.
Thanks,
Yiping

Hello Prashant Soni,
When creating a QCVS DDR project, in DDR configuration panel, when click "Read SPD", CodeWarrior Connection Server(CCS) will be invoked automatically on the right bottom of the task bar.
Please open CCS, type "log v", then click “Read SPD" again, the low level communication log will be printed in CCS, would you please send this log to me to do more investigation?
Thanks,
Yiping
