Hierarchical Design

Hi, 

I am trying to use the HWIcap but it fails when I initialize it. Here is part of the code:

#include "xparameters.h"
#include <xil_io.h>
#include <xstatus.h>
#include <stdlib.h>
#include "xhwicap_i.h"
#include "xhwicap.h"

static XHwIcap  HwIcap;

int main(void)
{
    int Status;
    XHwIcap_Config *ConfigPtr;

    ConfigPtr = XHwIcap_LookupConfig(XPAR_XPS_HWICAP_0_DEVICE_ID);
    if (ConfigPtr == NULL){
        print("HWICAP Lookup Config Failure\r\n");
        return XST_FAILURE;
    }
    print("After HWICAP LookupConfig\r\n");
    
    Status = XHwIcap_CfgInitialize(&HwIcap, ConfigPtr, ConfigPtr->BaseAddress);
    if (Status != XST_SUCCESS) {
        print("HWICAP Initialize Failure\r\n");
        return XST_FAILURE;
    }
    print("HWICAP Initialized\r\n");

    print("-- Exiting main() --\r\n");
    return 0;
}

I am working with a Digilent Genesys Virtex 5 (xcVLX50T 1136). I have tried reducing the frecuency of HWIcap but still is not working. The version of the HWIcap is v5_00_a on ISE 12.3.

Thanks in advance,

Alan

Hi, alan!

I'm a beginner in using HWICAP and may I ask you a question?

I got an error saying that XPAR_XPS_HWICAP_0_DEVICE_ID undeclared.

May I ask that have you ever met this problem and how did you solve it ?

Thank you very much!

Alan,

have you checked if the hwicap device address is setup correctly? There is a button in EDK to check your design. Have you tried this already? You may post your mhs file for further investigations.

Kuziniezov,

it sounds like your Device_ID was not generated to your xparameters.h. Please try to export your design to the sdk from inside the EDK-IDE. You may also recompile your drivers, sometimes it does the trick for me.

Best regards,

Luke
