IMX6D DDR CLOCK

[jfsong1]

I am designing an IMX6D board refereced from the IMX6Q evaluation kit. There are two clocks and four DDR chips in the evaluation board where one clock serves two DDR chips. Here I use two DDR chips in the IMX6D board. Can I use both of the clocks? One clock connects one DDR chip. Thanks.

Hello,

  Yes, it is possible to use both DRAM clocks.

Hi, Yuri

Thanks for your reply.

The evaluation board contains four ddr chips of 64bits, but my own board contains two ddr chips of 32bits. When I use both DRAM clocks for two ddr chips, should I make some special hardware and software modifications according to the evaluation board? What should I do in hardware especiallly ? For example, the two clocks should be configured  to use, or nothing should be done and it's ready to use. Below is my two ddr clocks connection reference. Is that right?

Thanks.

Hello,

  by default the both clocks are the same, therefore just use board design rules for DRAM
clocks and other signals.
