DDR3 Calibration
December 16, 2012 03:29AM
Hello,

I'm very interested in A10. I've designed a new custom board based on A10 reference design. Now I'm stuck at DDR3 initialization stage. I couldn't find out any information about the A10's DDR controller, how to perform the DDR3 calibration procedures such as read/write leveling, timing parameters and ZQ setting...

Everyone who have experiment with this ?

Regards,

Hello,

Thank you very much.

I had some questions about this problem from the Olimex blog, but there is no reply.
I think they're maybe stuck with DDR initialization like me. Developing an A10 custom board is very painful
because we don't have any infomation of the DDR controller although the chip's price is very good.

Regards.
