Data transfer between Processor and FPGA through GPMC using EDMA - linux

Question

We are working on a board containing AM3359 processor.
SDK we are using is ti-processor-sdk-linux-am335x-evm-05.00.00.15.
Our customer wants to see the throughput of the data transfer between processor (AM3359) and FPGA connected through 8 GPMC lines using EDMA
All we want now is to implement GPMC_EDMA data transfer program as per the below flow.
Processor and FPGA lines
Processor booted ----> Run GPMC_EDMA Data transfer program ----> Complete data transfer ----> Calculate throughput.
Here is my code for transferring data to FPGA through 8 GPMC lines.
#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
#include <termios.h>
#include <string.h>
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>
#include <time.h>
#include <sys/mman.h>
#define FATAL do { fprintf(stderr, "Error at line %d, file %s (%d) [%s]\n", \
__LINE__, __FILE__, errno, strerror(errno)); exit(1); } while(0)
int verbose = 0;
#define BUF_SIZE 4096
int main(){
int i,fd;char ch;
int buf[BUF_SIZE];
volatile uint8_t *map_base;
int a=1;
for(i=0;i<BUF_SIZE;i++){
if(i%100==0){
a++;
printf("i: %d, a: %d\n",i,a);
}
buf[i]=a;
}
//buf[BUF_SIZE]=43;
if((fd=open("/dev/mem", O_RDWR | O_SYNC)) == -1) {
printf("Error in opening gpmc\n");return 0;
}
printf("Successfully opened\n");
map_base =(uint8_t *) mmap((void*)0x01000000, 0x01000000, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0x01000000);
if(map_base == (void *) -1) FATAL;
if (verbose) {
printf("Memory mapped at address %p.\n", map_base);
fflush(stdout);
}
volatile uint32_t *p32 = (uint32_t *) &map_base[0x0800];
//while(1/*(ch=getchar())!='\n'*/){
//*p32 = 0x1;
for(i=0;i<BUF_SIZE;i++){
*p32 = buf[i];
}
printf("Sent %d bytes\n",BUF_SIZE);
//}
printf("Closing FD\n");
close(fd);
}
Someone kindly help me to proceed further as we have a severe time restriction and also we are new to this one.
