The recommended way of configuring the DDR for AM57x devices is by using the EMIF tool.
The tool is present online.
Steps to be followed:
GEL file update for AM57x,
Board library update for AM57x,
*<X> - 1/2/4 for AM571/2/4.
*<YYY> - 666 for AM571/4 & 532 for AM572.
We recommend that you test the settings in CCS by creating a GEL file with the modified settings before modifying the source in the board library.
Follow section 3.4 under Application Report for more debug resources.
For updating the <pdk_root_folder>\packages\ti\board\src\<board>\<board>_ddr.c file, please keep following pointers in mind:
In this "ddr3Config1.emifDdrParam.sdramTim1" is SDRAMTIME1 and so on.
