LS1012A DDR3L support list

AlanYL — Wed, 13 Sep 2023 05:56:54 GMT

The ddr chip used on the LS1012A development board are MICRON MT41K512M16HA-125
But our case will uses Winbond W638GU6QB series or ISSI IS43TR16512BL series.
How can I check the DDR chips supported with 1GB?
And how to support new DDR chips?

Thanks!

Since the DRAM configuration is the same between the DRAM part numbers you have listed (Micron, Winbond, and ISSI), it should simply work with the existing board and existing setting/SW. no change is needed.

Hi Yipingwang,

Do we need to tune the DDR parameter and does LS1012A have the DDR tuning utility for reference?

Thanks!

You could use QCVS DDRv tool provided in CodeWarrior to do DDR optimization and validation.
