F28377D EMIF to SDRAM

I try to use EMIF1 on F28377D to interface with sdram (IS42S16400F). I already spend a couple days on it. I still can not figure out how to program it. The emif to sdram examples I can find are all about DSPs, nothing about this MCU. Does anybody can help me take a look at the following program? I know it has a lot of mistakes.

I just want to write some digital numbers into SDRAM, and read them out.

#include "F28x_Project.h"     // Device Headerfile and Examples Include File
#include "F2837xD_Emif.h"
#include <stdio.h>
//#include <std.h>

Uint32 *Src_StartAdd;
Uint32 *Dst_StartAdd;
Uint32 *Src_EndAdd;
Uint32 *Dst_EndAdd;
Uint32 TempData;
Uint32 DataBuff[2048]={0};
Uint32 ReceiveData[2048] = {0};
