ECC configuration in QCVS fails the validation tool

my ddr configurations works fine in QCVS without ECC enabled. I enabled ecc by setting these two items


ECC(Error Checking and Correction).          Enabled

Accumulated ECC enable.                           yes


However, the validation failed… 


DDR initialization failed : Invalid value at 0xF04 : 0x00001102

and there is a ACE error detection.



I am using 4 of 512MB * 16 bit DDR for memory and 1 of same DDR for 4 bit ECC, our data is 32bit.

I set all the DQ mapping including ECC's to Default, as our layout is 1 to 1 mapping…. 



Is there anything missing.
