Halo，everyone.
I use VDMA to build video channel in my vivado project, i use cmos sensor ov5640 to capture image，and it works well. My system is below
and my sdk code like below:
/*
* main.c

* Created on: 2019年05月10日

#include "I2C_16bit.h"
#include "xiicps.h"

#include "xparameters.h"
#include "sleep.h"

XIicPs Iic;
int main()
{
xil_printf("%d", Xil_In32(POWER_DONE));
xil_printf("Sensor reset done\tIIC init start\r\n");
I2C_config_init();
Xil_Out32((VDMA_BASEADDR + 0x030), 0x108B);// enable circular mode
Xil_Out32((VDMA_BASEADDR + 0x0AC), VIDEO_BASEADDR0); // start address
Xil_Out32((VDMA_BASEADDR + 0x0B0), VIDEO_BASEADDR1); // start address

Xil_Out32((VDMA_BASEADDR + 0x0A4), (H_ACTIVE*3)); // h size (H_ACTIVE * 3) bytes

Xil_Out32((VDMA_BASEADDR + 0x054), (H_ACTIVE*3)); // h size (H_ACTIVE * 3) bytes
Xil_Out32((VDMA_BASEADDR + 0x050), V_ACTIVE); // v size (V_ACTIVE)
while (1) ;
return 0;

Actually, i can see very clear video caputered by camera on the monitor, but i wanna to access the image saved in ddr memory, then i open memory viewer in debug mode , nothing happened.
What solution i had tried?
I think the problem maybe vivado sdk, i uninstalled vivado2018.2, installed vitis and vivado2020.1 .. doest work ethier
I have been busy with this matter for many days， Thank u for help!
