Hi @Vinit_Khadakabhavi

- Do you have multiple download cables connected to your computer?

- Have you looked in Event Viewer to check if the driver shows any errors?

- Does the ACT light from the USB blaster cable has a constant or intermittent shining?

- If possible, can you try using the current USB Blaster on another PC and another working board?

    No there are no multiple download cables.

    i have tried on different PC as well, still the same error.

    The usb blaster has only power light lit up, there no light on ACT. Is it the problem?

      Could you please follow the troubleshoot guide I previously shared? A.1. Windows Troubleshooting Procedure for Intel® FPGA Download Cable

      The USB blaster should only have one LED, which is the activity LED. If the light is blinking and you are not programming anything, it could mean that the cable is faulty. If the light doesn't blink but it is on, it's fine.

      If the steps from the troubleshoot guide do not work can you share the following tests?:

      - Can you try running jtagconfig in a NIOS command prompt window?

      - Did you see any errors from the USB driver in the Windows Event Viewer app?
