DDR validation failed

[412149526]

What could be the cause of DDR validation write leveing failed, and how to solve it? The configuration and error information of DDR are as follows:

[412149526]

The attachment is part of ddr schematic diagram, ddr datasheet and ddr validation report。DQ map configuration is 0x1. Only the CL-nRCD-nRP timing parameter in the ddr datasheet is 22. Because the emulator is used, clk to DQS Skew is not filled in.The following are the register configuration values generated by the QCVS tool：

In DDRv Report ERR_DETECT[ACE] is set, ERR_SBE[SBEC] is set.

For ECC failures during the operation, please configure DDR properties according to DDR datasheet, use the validation section of QCVS to optimize the setting. if ECC persist with optimized setting then there may be a HW issue (check the AN5097 for the layout guidelines).

[412149526]

What attributes do you generally need to configure according to the DDR datasheet? We are now using QCVS for validation, but the first item cannot be passed and this kind of error is reported. In our QCVS configuration, ECC is prohibited.

[yipingwang]

In the CCS console, please type "log v", then connect to the target board again, the low level CCS log will be printed in the console, please provide this log.

how to open CCS console，thanks

[yipingwang]

CCS  is at the right bottom of the task bar, please double click to open it.

[yipingwang]

Please configure the Properties panel according to the DDR datasheet. If there is DDR SPD on your target board, please create QCVS DDR project with reading from SPD method. RCW on the target board should be valid. Enter MCK to DQS skews in the DDR wizard, verify the DQn_MAP registers are correct.

In the Summary panel in CodeWarrior IDE, you could check some registers value, please check whether ERR_DETECT[ACE] is set, and whether ERR_SBE[SBEC] is set.

If ERR_DETECT[ACE] is set, please refer to my last reply in https://community.nxp.com/message/1208703?commentID=1208703#comment-1208703
