SW1 Glow RED when I connect USB cable

Former Member

I have seen this strange behavior with my zedboard, when I connect usb as power cable SW1 glows RED and D5-R41 Blue. This behavior is irrespective of boot_mode jumper settings JP1-JP3, I'm unable to boot the board.

Can anyone help?

    SW1 is a push-button, so it should not be glowing. If it is, you have a much more serious problem.

     

    I suspect you meant D3 on MicroZed which is above SW1. This is an LED under user control. When in JTAG mode or if the board is unconfigured, it is expected that this LED will glow red.

     

    D5 is a green LED that lights when power is good. It is expected that this should light under all normal conditions.

     

    If you are having trouble configuring the board, try the following:

    1.   Use a known good bitstream that matches your MicroZed. Is it a 7010 or 7020?
    2.   Double-check your JTAG connection. Is your cable good? Have you tried using iMPACT to query the board?
    3.   Use JTAG with SDK to connect to your board.
    4.   Follow Tutorials 01 through 04 on the MicroZed Reference Design page.
