a few questions,

I am experienced in electronics, soldering to pcb ... and well equipped.

Have done both my x360 with coolrunner and qsb
-falcon , phat
-trinity , slim

I was expecting the former to be a piece of cake and the second to have more chance challenge.

In fact the slim is perfect 15 to 30 sec consistently, only one non-boot in 50 attempts.

The phat falcon is the one causing me issue. When he glitches it is quick (5 to 10 sec) but it is only one out of 3 attempts. If it is not in the first 15 sec then he does not glitch at all.
-I have swapped the coolrunner with the other
-changed all wires for the set in the other coolrunner package
-retouched all soldering
-tried cap on/off
-slim on/phat on
-reprog the coolrunner
-did images with xebuild and jtag tools
-flashed them with both jtag tools and rawflash...

questions
1)what could be the issue on the phat?

also I plan on keeping only one RGH and returning the other to stock programming; do I simply
2) reflash with original nanddump.bin, and
3) disconnect the power on coolrunner

if one day I want to return it to RGH, do I need to do both steps (.ecc, then .bin) or can I simply flash the updflash.bin with jtag tools or nandpro?

prolly wire positioning/length for the falcon. My falcon was extremely sensitive to how one of the wire was set up.

Im not a pro, but 2) and 3) sounds about right (may have to unsolder the coolrunner wire too?) and u should need only the .bin. But u should have someone else confirm this

Falcon boot times should be almost instant, check your wiring and re-locate the underside wires away from the coils.

With regards to returning a glitched console to stock, simply flash the stock NAND back, remove the CoolRunner and all should be well.

have u tried insulating the wires? i had a falcon and whenever i put it back in the case it would only boot up 15-20% of the time when it didnt boot up it just sounded like a revving xbox

When using the console normally I.e day to day use, who sits powering on then off then on then off ? No one.

You turn on once and it boots and you play. So play.

agreed , but that is the issue. It sometimes boot twice in a row and sometimes I have to boot 5 times before it glitches ( and that is not very good)

I was carefull with the wiring location (vs coil), but will try different routing to see if it helps,

thks all,

1-tried several routing
2-tried blue wire to the connection point on top (near fan shroud)
3-tried green wires rerouted by the fans (instead of small hole)
4-replaced yellow, blue, green with shielded coax (rg316)
5-replaced yellow, blue, green with wire from cat-5
6-tried an image from multi-biulder 0.4 (i am on 13604)
7-it was ok on the microscope but redid the stdby-clk soldering to be sure
(also from first post tried two different coolrunner on it)

well, always the same behavior, it boots one out of 5 (immediately when it boots ot not at all)

at this point coming to the conclusion that since the behavior is always the same with all these permutation that this part is not the issue, and the electrical level is fine.

questions
------------
-it is a falcon (with cb 5771), can you have one of these that will resist glitch ??

-on the software side only thing I did not rewrite was the image.ecc , am I ok to assume that when I rewrite the nandflash.bin images that the ecc part is embedded in that ? (since I tried three soft jtagtools, xebuild and multi-builder I consider they cannot all produce bad output and exclude a bad .bin file)

-I programmed my coolrunner with nand-x and jatgtools, any other way to prog the coolrunner??

-any other ideas:smile: ?

found a post by blakey8 on flashing to coolrunner with nandpro (thks blakey8), ussing timing files from post by ubergeek.
Unfortunately does not make a difference on how my falcon glitches.

-is the ecc memory flashed a different memory zone than the nand? or do we overwrite that when we flash the nand?

if it is the latter then :frown: I am out of ideas, feel I covered everything by at least 2 or 3 methods.
if it is a different memory zone, could it be the ecc?? and what other tool than jtagtool to generate one.

created ecc's and flashed them, same results (so three ecc in total)

will take pics sometime this week and post them.

at this point out of ideas really

thks for the feed back teajunkie (i am a tea junkie too:biggrin:),

I had ordered 2 coolrunner one for my slim (working a1)
so I had two sets of CR wires for Phat and I tried both sets, then I tried with thin coax rg316 to get shielding, and then cat 5 wires (those in the pics)

all the exact same results, which leads me to think it is not what is causing the issue.

that being said, if it can help I have no prob going back to the original wiring but it does not seem to change much the behavior.

something else seems to prevent the glitching but have the feeling I have tried everything 2 or 3 ways at this point:confused:

Probabily long shot but your B point on qsb (r4b24) might be shorting to c3b2. worth checking
