Overview [edit]

The purpose of this sheet  File:C6A8168 DDR register caculate sheet V1.1.zip is to help calculating DM816x, C6A816x, and AM389x DDR2/3 register values. There is not much difference between DDR2 and DDR3 timing calculation.

Input data from DDR device datasheet into blue cell in the excel file, and register values are automatically generated in red text in yellow cells. Update these register values to UBoot ddr_def.h  or gel file.

Besides this timing registers configuration, don't forget to do SW Leveling according to DM816x_C6A816x_AM389x_DDR3_Init.


Note: If the result cell isn't displayed correctly like #NAME?, #VALUE!, enable excel menu Tools->Add-Ins...->Analysis ToolPak and Analysis ToolPak-VBA check box.
