How to configure DDR initialization script with 933MHz DDR3LMemory ?

peteramond — Fri, 06 Apr 2018 10:39:08 GMT

Hi All,

This is a custom hardware design with;

Processor - iMAX6Q - MCIMX6Q6AVT10AC

RAM - 933MHz Micron DDR3L - MT41K256M16TW-107 IT:P

1) Here is the configuration for the script. Can you check and tell me the configurations are correct or not ?

2) Don't you have different script generator for DDR3L type memories (Low Power RAM) ?

3) In memory type I don't have to select DDR3L-933 option. What should I select ?

4) In DRAM clock frequency I don't have to select any option for 933MHz. What should I select ?

5) Under SI configuration section what should I select for

DRAM DSE Setting - DQ/DQM (ohm)

DRAM DSE Setting - ADDR/CMD/CTL (ohm)

....etc.

Can you give me an idea on this SI configuration parameters. Under which conditions of the memory should we change those values and how ?

Waiting for a detailed explanation for this.

Regards & Thanks,

Peter.

Hello,

Customers can use DDR3 script for i.MX6Q:

i.MX6DQ SABRE SDP/B DDR3 Register Programming Aid

Also, the following may be helpful:

Freescale i.MX6 DRAM Port Application Guide-DDR3

I.MX6 MMDC supports memory up to 532MHz, there fore all timings

should be selected based on this maximal frequency, say DDR3-800 or DDR3-1060

Have a great day,
Yuri
