Hello everyone,
The above design is for Standard SPI in IP mode is set to Standard. We are able to see data,SCK & SS in ILA as showned in above image.
The above design is for Quad SPI in IP mode is set to Quad. We are not able to see data in ILA as showned in above image.
Vitis code
#include <stdio.h>
//#include "platform.h"
#include "xil_printf.h"
#include "xparameters.h" /* XPAR parameters */

#include "sleep.h"
//#include "ps7_init.h"

* xparameters.h file. They are defined here such that a user can easily
* change all the needed parameters in one place.

/*

static XSpi SpiInstance; /* The instance of the SPI device */
/*

*/
u8 ReadBuffer[BUFFER_SIZE];

int main(void)
{
// init_platform();
int Status;
/*

*/
Status = SpiPolledExample(&SpiInstance, SPI_DEVICE_ID);
if (Status != XST_SUCCESS) {
return XST_FAILURE;
}
//return XST_SUCCESS;
// cleanup_platform();
return 0;
}
In IP data sheet
1.C_SPI_MODE = 0 for Standard SPI
2. C_SPI_MODE = 1 for Dual SPI
3. C_SPI_MODE = 2 for Quad SPI
We have done settings as per data sheet but we are not getting any data in ILA for Quad mode pls suggest us is there any other settings for Quad mode.
