Part Number: AM3358

Hello All,

I have a custom board designed for the AM3358 processor with DDR3L ram. After following the wiki link for the levelling part, and running the EDMA test in CCS V7, it is observed that the test fails at address locations  ending with 0. Can anyboady please help me in understanding as to what is going wrong. The test output file is attached.

    Is this a single board, or do you see the same issue on multiple boards?

    As of now this issue was seen on a single board. Other boards were not tested. Any how, after a couple of tweaks with the ratio seed values, i got it to work by changing the value of PHY_INVERT_CLKOUT from 0 to 1. This seems strange as my clock trace length is greater then DQS trace, hence PHY_INVERT_CLKOUT should be 0. I will be check the same on the other boards and get back.
