Procedure after fx firmware update.

[Zenith]

Hello.
After firmware update, open fails.
What is the proper procedure?

char p[] = "a.img";
CCyFX3Device* Fx = new CCyFX3Device();
if (Fx->IsBootLoaderRunning())
{
        cout << "IsBootLoaderRunning " << endl;
      if ( Fx->DownloadFw(p, RAM) == 0)
           cout << "FW Success !! \n" << endl;

}

CCyUSBDevice* USBDevice = new CCyUSBDevice(NULL);
int count = USBDevice->DeviceCount();
cout << hex << "Device Count = 0x" << count << endl;

if (USBDevice->Open(0) == false)
       cout << "Open Fail \n" << endl;                     // <---------------fail....

cout << "Finished. \n" << endl;

Hi,

Could you try Opening the device before Downloading the firmware onto it and check if the issue is seen

if(Fx->Open(0))  {   //Check if boot loader is running.    status = Fx->IsBootLoaderRunning();   if(status)    {     // Download the file C:\Bulkloop.img file to FX3 device RAM      dwld_status = Fx->DownloadFw(p,RAM)    }  }

Firmware update was completed normally.

Hi,

The object Fx of the CCyFX3Device can itself be used after the downloading of the firmware onto the RAM. CCyFX3Device is an extension of the CCyUsbDevice class.

Please provide some delay after downloading firmware onto RAM to allow FX3 to enumerate with the new firmware.
