RGH RGH 2.0 Jasper 16MB TX Rev C wont Glitch

[AkhmedovIR]

Hello.

I have a Jasper 16MB. CB 6753, Dash 14719. Installed Coolrunner Rev C. Dump of NAND is clear, make ECC with JRunner (last version) - won't glitch and can't get Xell. I tried all jumpers settings and all timings - nothing. I try flash back original NAND - work perfect. Again try make ECC and write - won't glitch. I try wait 5-10 min. - nothing. Try turn on with power key and eject key - nothing. Tested all points with multimeter - all fine, no shorts and faults. Green light on the coolrunner blinking (not blink with B and C timings). What can i do?

 

[lio_x]

your soldering looks fine
can you post a photo of the CR install?
and a log of jrunner

 

[Martin C]

When you say all timings, did you also try with the falconrgh2.xsvf? If not, do so. I've had Jasper RGH2s glitch well with this file.

 

[gumpy39]

have you tried other timings files

 

[Mikaz]

Just throw away that shielded cable. Had same problem with few jaspers. Used normal blue cable and all worker perfect. I recomend to place blue cable on top of coolers.

I don't have more photo, because motherboard in the office, only tomorrow i can get it. Here is the log, but without writing ECC to the NAND (again because mb in the office), but i did it.

I know about it, and try use normal cable - nothing.

Just to align with the other guys,

My RGH 2.0 wouldn't work until I used the A timing file without the 10 ohm resistor. I also switched back to the normal blue wire, ran underneath, like the first RGH method.

Worked just fine after that.

EDIT: This was on my Jasper 16MB Elite.

Yes, i did this - not help.

 

[Mikaz]

Just forget that shielded crap. Causing problem for a lot of people.

I had a similar case, but i already try this method on this Jasper and nothing

totally agree

How long is your debug light staying on for?

 

[AkhmedovIR]

How long is your debug light staying on for?

differently, depending on the selected file with timing and cable settings: sometimes flashes very quickly, sometimes burns about 1-2 seconds.

 

[WNYConsoles]

Did you try switching around 1 2 3 and bridge/unbridge JP? Try removing double-shielded coax and replace with regular RST wire, add 68nF in-line RST, etc etc.

68nf in-line with CPU_RST is dangerously high.

I would recommend starting with a 470pF in parallel with a 3.3k resistor for starters and work from there.

It should be the same timing every cycle, which makes me think you have unwanted interference somewhere.

Try switching 1 2 3.
Try bridge/unbridge JP and CAP.
Try shielded and regular cable.
Try different cable and timing settings.
Check all solder points with multimeter.
Doesn't try add 68nf - try it tomorrow.

Thanks all for information, i will try all it tomorrow and write here a result.

 

[lio_x]

did you removed the 00 caps on the CR?

I usually use shielded cable without soldering it to the ground (and no 10 ohm resistor too). I tried that on many RGH 2.0 consoles using rev B and it boots fine. Try it using rev C..hope it helps.

 

[AkhmedovIR]

Fixed. Work only with standard cable,placed on the top of air tunnel, only 28,5 cm long, - 5 millimeters plus or minus - doesn't glitch. Maybe it help somebody. Glitch time - 15-45 seconds.

 

[SOD_FrosT]

That's odd that the length of the wire would stop it from booting totally... these RGH systems are so fricking complex, no wonder I started with JTags. LOL!
