I am working on data transferring from PL to DDR RAM. When I run the software application using JTAG, I could read and write to DDR from PS. But the data I write to DDR from my AXI DMA ,does not write on the DDR when my application is running. But after I stopped the application and re-run the application without switching off the board, the data is written on the DDR RAM. My guess is the problem is in my main() function. I may not be calling all the functions to configure the hardware platform correctly. But I can not figure out what it is. This is a sketch of my main() function and headers included in the program. I am using SDK 2016.1 and Vivado 2016.1 for my design.
#include <stdio.h>
#include "platform.h"
#include "ps7_init.h"
#include "xil_printf.h"
#include "xil_io.h"
#include "xscugic.h"
#include "xparameters.h"
#include "xgpio.h"
int main()
{
// Initializing hardware platform
xil_printf("Initializing Hardware platform.....\n\r");
init_platform();
// ps7_post_config() to enable the level shifters @PS-PL boundary and release the RESET signal to enable the PL
ps7_post_config();
/******* program body ********/
// DMA initialization
//Interrupt initialization
//GPIO initialization
// infinite loop
while(1){
.
.
.
}
/******* end of body ********/
cleanup_platform();
return 0;
}
I am stuck here for few days now. But still could not find the solution. Hope some can resolve this issue. Thanks in advance..
