My solution for no CoolRunner green blinking & freezing

I'm not sure if it's been mentioned here or not, but I discovered something odd when I glitched my 512MB Jasper board. Originally I was having a fast fan with an odd rhythm and no green light blinking. The odd rhythm sounded akin to a car revving to it's rev limiter.

I had everything installed exactly per the pictures: http://team-xecuter.com/forums/showthread.php?t=74857 all the way down to wire routing and hot glue blobs.

I gave up for a while and spent the next few days reading everything I could on my favorite forums.

I tried many things, reprogramming the CoolRunner, rebuilding the ecc image and re-writing it, resoldering my connections, no luck. I could always flash to stock and disable the CoolRunner and it would boot fine.

I eventually came across (don't remember where) a thread where someone had better results when one of their wires WASN'T tacked down to the board, but left hanging freely. I experimented with this and I noticed that when the green wire (PLL_BYPASS) was held down to the board, my fans acted that way and no blinking, but if I pulled it away (by hand), my fans would calm down and the green light began blinking, and then the console booted XeLL! There was a delay of about a sec from the wire being moved and the fans spinning up/slowing down. If I moved the wire back after XeLL had booted, the console would freeze and I'd have to power off to start over.

Through some experimentation with positioning, I was able to secure the green wire to the board (not dangling), but it was higher up (towards the x-clamps).

I do have a 0.1uF cap between PLL_BYPASS and gnd, I tried that (without luck) before I tried moving the wires. It boots up in no more than three pulses now, so I didn't want to change anything. So it may or may not be helping/doing anything.

This may not help everyone, but it was definitely my problem. It may even be linked to some's freezing issues. Like I said, wire here no blink, wire there blink and boot. Thanks for reading. I hope this helps someone.

Edit: I can confirm that a repositioning of the wires cured my 256MB Jasper from it's nasty freezing problem.

Re: My solution for no green blinking.

mine are away from the coils, but my 16mb jasper still freezes during gameplay - I thought it may be an error starting but.........???.....

Re: My solution for no green blinking.

mate my jasper freezes all the time and has done since day one, always boots fine after restarting though so i don't worry about a fault anymore, the amount of abuse it gets if it was onset of a fault it would have happened ages ago. the poor thing can hardly breathe where i have it so blame it on that.

Re: My solution for no green blinking.

I can confirm that moving the wire made all the difference. I have been trying for 2 days to get my 2 Jasper 512's to boot ut neither one would even boot once. Since I mover the wire they boot up instantly and I do not have the 68nf or any cap installed. Thank you so much...this was driving me crazy.

Re: My solution for no green blinking.

yeah - I couldn't get mine to glitch untill I moved the wires, but since the coolrunner, I get slow boot and freezing during gamplay - no issues prior - just did a trinity and that's flawless

Re: My solution for no green blinking.

I had the exact same problem on a falcon. Here is the way i have positioned the wires on the motherboard.

Re: My solution for no green blinking.

same happened to me on my 16mb jasper, when i had the wires taped down it wouldn't glitch at all until i started moving the wires around, at one stage it would only boot lying down flat but not when standing. in the end i just left the wires hanging freely, now it boots up instantly with the odd freezing now and again.

Re: My solution for no green blinking.

but I dont have a JTAG :( lol
I think I'm going to play around with the cables and add a QSB to see if it helps - will post back here with results for anyone else that is interested lol

Re: My solution for no green blinking.

I had the exact same problem on a falcon. Here is the way i have positioned the wires on the motherboard.
I had problems with a Falcon as well. First time around I wired them with the yellow wire coiled. It glitched once every 5-10 tries.. not acceptable really.

I then used the original wiring (as per Ubergeek's phat bottom picture (no pun intended :)), but that wouldn't glitch at all.

And then I decided to wire it as I wired another falcon in the past which I glitched using a custom glitchmod pcb.

I don't have a picture here, but it consists in making yellow and green as short as possible and connecting the blue wire topside and routing it along the two heatsinks.

This wiring has been giving me <5 secs to dash and <3 secs to xell every single time.

If you ever strip the case I'd be interested in a pic please. I had a real PITA Falcon (posted on here about it). Thing was it booted Xell EVERY time no probs but wouldn't boot to dash EVER. I have just stripped the green wire and repositioned. Here's the strange thing, I left it hot glued to the board precisely the same however instead of coming in left to right I soldered with the wire angled in to the point on the board right to left. Also bear in mind previously the soldering checked out 100% with multimeter AND I have a really good microscope so I know there was nothing wrong on that score. I'm convinced that along with the correct length of wire there is certainly also a sweet spot in which to route your wires.
This Falcon now has a 98% boot rate within around 4 seconds.

Re: My solution for no green blinking.

I have mine ran just about like WestBox's, and like AudioPro says, avoid the coils. XeLL would slow down when the blue was near the back of those inductors.

I'm glad that my post helped someone!

Looks like someone else fixed their problem the same way: http://team-xecuter.com/forums/showpost.php?p=478917&postcount=14

Maybe TX should update their install pics?

Edit: I wish I could update the title of the thread to include 'freezing', it may help more people that way.

Added to Phat guides. Hope it helps and thanks to Westbox and the others who tested this.

UPDATE: It has been reported that some consoles have trouble booting or boot fine but freeze frequently. One of our members, Westbox found that if he routed the wires a little differently on the back of his board he get perfect boots every time with no freezing. Here is his diagram:

Awesome, thanks Uber for updating the guide and also updating the thread title! May it save many headaches.

I like it, we learn more each day. From caps on BB Jaspers to routing of the wire. The knowledge shared around here is what keeps me coming back and looking in every day.
