Question on DDR calibration script

[t_kuha]

I noticed there are two different tools for DDR calibration:

- DDR3 Register Programming Aid (i.MX6DQ SABRE SDP/B DDR3 Register Programming Aid)

- i.MX6DQSDL DDR3 Script Aid ( i.MX6DQSDL DDR3 Script Aid)

What is the difference between them?

Which one should be used if I want to determine DDR initialization values to be used in u-boot?

Regards,

Hi,

Here recommend you to use the - i.MX6DQSDL DDR3 Script Aid ( i.MX6DQSDL DDR3 Script Aid). It's newer and have more option than the other one. When you open the link you can see the details.

The - DDR3 Register Programming Aid (i.MX6DQ SABRE SDP/B DDR3 Register Programming Aid) is only for MX6Q_SabreSD_DDR3_register.
Have a great day,
Rita
