Unable to read device chain - JTAG chain broken

Captured DR after reset = (0343B0DD)

Captured IR after reset = ()

Captured Bypass after reset = (0)

Captured Bypass chain = ()

How to solve this problem. Thanks

    Hello,


    To start debug, we need more information from you:

    1. Is this board you designed? or is this devkit?
    2. how many boards you see this failure?
    3. have you change the USB Blaster II programming cable and see if this can solve the issue?

    regards,

    Farabi
