Hello all!

We are designed and made just now custom board on DM8168 CPU with two DDR3 banks and 8x RAM ICs with type MT41J512M8JP-125:G respectively.

But we cannot boot this board with our boot SD-Card that successfully booting for the same custom board with difference only type of RAM ICs (MT41J128M8JP-125:G). Could anybody provide any information about ways to solve this problem?

Thank you very much!

    Hi Sammy,

    I think DM8168 device supports up to 2Gbyte DDR3 RAM memory.

    DM816x datasheet states:

    Dual 32-Bit DDR2 and DDR3 SDRAM Interfaces
    – Supports up to DDR2-800 and DDR3-1600
    – Up to Eight x8 Devices Total
    – 2 GB Total Address Space
