IMX6d6 , self made board. DDR3 528MHz. We made more than there hundred boards . About half of them hanged up after running several hours. Now we want to run it at a lower DDR frequency
For our reference board, the 400MHz is the ideal value. The DDR frequency support depend on hardware design. Here recommend you to use the 400MHz or lower for you board.
Thank you for reply!
Today, we found the board can ran stably when switch off the CPU1. It's strange. We cann't konw what happened . and don't know what's the problem. We tested the supply, it's very good.
