    How to add a debug light to matrix , digilent or TIAO Xilinx XC2C64A CoolRunn board

    This Tutorial will show you how to add a debug light to your matrix , xlink digilent or TIAO Xilinx XC2C64A CoolRunn glitch board.

    You can use a smd led or a 3mm led what ever you want your choice.

    This will help you debug a console that is not glitching because if the light is not blinking every 5 seconds or if it is not lighting up at all. you dont have your wires on correctly

    ( so if the lights not blinking the console will never boot so go back through your wires and find the problem get it fixed and get that light blinking)


    On fats and slims the light should repeat blinking every 5 seconds untill the console boots.

    Proper pattern of the blinking ensures NAND CB works and all wires except reset are good.











    you can use a smd led light for this if you want and they come in three differnt models they are

    0603,1206 and 0805 all are differnt sizes.

    The chart below will get you close to what resistor you need for what ever color smd led you are useing.

    (difernt colors need differnt resistor)

    smd led chart

    Red LED = 51 to 82 ohms

    Orange LED = 43 to 62 ohms

    Yellow LED = 43 to 62 ohms

    Green LED = 36 to 52 ohms

    blue LED = 15 ohms

    pink LED = 15 to 24 ohms

    High Bright Red = 51 ohms

    White LED = cant use because it draws 3.4v and the supply voltage is 3.3v





    As you can see below some 3 mm lights draw more than 3.3v so be carefull.

    only insall a light that draws under 3.3v and make sure to use a resistor between the

    positive debug pad on the glitcher and the pos legg on the light

    3 mm led

    White LED bulbs: 3.2 - 3.4V,
    Red LED bulbs: 1.9 - 2.1V,
    Yellow LED bulbs: 1.9 - 2.1V,
    Blue LED bulbs: 3.2 - 3.4V,
    Green LED bulbs: 3.2 - 3.4V,

    To see what ohm resistor to use for 3mm leds refer to the smd led chart.

    check this out the debug light in action.

    After getting this to work correctly i then had a idea to make one of the ring of lights be the debug light.

    So i then installed another led on the rol board and this is what it looks like booting. console fully put back together watch the vid

    make it simple, the Glitch-Debug led could be applied to pin 27 of XC2C64A on any "RGH module". right ?

    like the idea using the ROL for Glitch debug. it's a brilliant idea !

    I used this guide for the first time today. I used a red non-bright Red LED with a 120 ohm resistor and it worked out great. Thanks for the contribution.

    I would probably invert the signal and put it on the power light.

    So basically the power light will flash off when attempting the glitch and be solid once its done its thing.
