Greetings Jun,

I'm not quite sure what you're asking for, please see the JEDEC specification on DDR for voltage ramp and device initialization, this will detail all the requirements for clocks, reset, power supplies, and all other signals.

If you're looking for software examples of configuring DDR on the SoC, please see the MCU+SDK or Linux SDK. For example, the MCU+SDK has a detailed driver page about their DDR S/W: https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/09_01_00_41/exports/docs/api_guide_am64x/DRIVERS_DDR_PAGE.html

Sincerely,

Lucas
