the doux2 blue and white both have these and i think it would be cool for the lite to have one also. would i just use points on the pinheader (chip side) ?

2. it says in my first post "how would i go about making a activity led for the doux2 lite?
the doux2 blue and white both have these" you know how there is a light on the chip
i want to make a light that goes on an flashes when the chip is on

Well the DuoX2 Blue and White both have 2 512k banks and a RED flashing LED and cost around $2 more
The DuoX2 Lite has only 1 512k bank and No LED and is around $2 cheaper !
Now are you serious ? you saved like $2 but now want to add your own LED to tell you the chip is on ?
You can connect a flashing led to pin 2 ground and pin 6 5v and it will flash all the time , it doesn't matter if the chip is on or off but you cant add a LED that will flash only when the chip is on as this needs to be driven from the CPLD code on the modchip itself ... for this pay the extra $2

D0 goes to ground when mods is enabled completing the circuit from 5v on pin 6.
Everyone who answered this to this point just got an F in the gradebook. Step away from the soldering iron please don't touch any more Xboxes.

right d0 goes to ground when chip is enabled.... but what level(s) does d0 run at while the chip is disabled

According to an earlier post by Hippo D0 sits at 1.2V when the chip is enabled its not grounded. I think he mentioned that another 0.4v higher and the chip would not work.

Grade changed to F MINUS for arguing with the teacher.
If you wanted further discussion about that post why did you lock the thread? Why must you always bicker? And this is all you have to say for yourself?

This is about this thread. You stated previously, cannot remember the thread exactly about the voltages, now you say its ground? will this method still work withe D0 sat at 1.2v?
Do you really need to ask that question.
Also you have a rather high opinion of yourself if you think you are my teacher.

Doesn't matter, it's not ground 
hippo's solution should work just fine

see the arguement that has happend from just one question
i have 15 red leds laying around and i wanted to just try something different and put a activity led on a duox2 lite
i just wanted to know how if it was possible

Ghost you could always temporary wire one in and see how it behaves.
You could connect via a 100R resistor to pin 14 of the cpld chip and ground (Pin 2)
So it would be
Pin2-------LED------100R------Pin14 CPLD
I will double check the number again in 10 minutes. If I could count it would help

pin 14 of the cpld chip
is that on the chip itself or somewhere else? could you show a pic of this spot

I don't have a large picture of the chip yet. From pin 1 just count 14 to the right or email me a large clear pic and I will add the use ful bit on to it and repost it.

I suspect there are a couple more solutions waiting to be discoverd like possible changes in voltage on the flashrom's #WP, #CE and #OE lines. The easiest way is use the Jtag interface and run unitag universal scan and you'll get some color changes when the pin changes and all pins are displayed on screen. Also I think it's set up like a constraints screen where you can drag and drop signal names on to pins.

This is the 'hello world' of passive analog circuit design it either works for you or you wired it wrong.

well i got it to work
but
the chip is gone and dead now
i soldered it to the pin and the pin lifted so i put it in my box any way to test it
light goes on took the chip out and the led fell off said shit a few times and put it back on to see if it worked
nope
so i stabbed it with my soldering iron and now the chip is dead (kinda smells like mini wheat)
not much a loss because these are $9 for a new one

It is a small point.
If you replace the chip get a DuoX 2 Blue and save yourself some miniature soldering
