Hi, 

I would like to change the timing configuration for the DDR3 controller on the I.MX7 chip.  I could not find infomation  regarding these registers.

Thanks

Omar

Hello Omar,

the descriptions of the registers can be found in the Reference manual - Chapter 9 - DDR Controller and DDR PHY sections depending on which timings you want to change. Detailed descriptions of the timing parameters can be found in the JEDEC specifications.

Best Regards,

Jan

Hi, Jan:

Could you provide me the reference manual? Or just send me a link to it?

I have others, like: power consumtion measurement, Hardware Development Guide, etc...but not the reference manual your pointing out.

Regards

Omar
