Hello Cambest Lewis,
Please open the CCS(CodeWarrior Connection Server) console at the right bottom of the task bar, type "log v" command, then connect to target board again, the detailed low level communication information will be captured, please send the CCS log to me to do more investigation.
In addition, if there is DDR SPD on your custom board, please use reading from SPD method to create a QCVS DDR project.
If there is no SPD on your target board, please create a QCVS DDR project with the default configuration and configure the DDR related properties in the DDR QCVS project according to the DDR datasheet, then generate the initial DDR controller configuration and connect to the target board to do optimization and validation.
For details, please refer to DDRv user manual https://www.nxp.com/docs/en/user-guide/QCVS_DDR_User_Guide.pdf?fsrch=1&sr=10&pageNum=1.
Have a great day,
TIC
