Falcon 6754, CR Rev c advice

[Chura]

Hi Guys,

I'm helping a friend, and installing on his Jasper 16M the Rev C CR.
I read NAND just fine, wrote ECC, Installed CR and I think its good installation (steady red and trying to Glitch)
I tried all jamper options, tried a-d timing and even falcon one. nothing get this crap boot.

Any advice?

google rgh1.2

Yep rgh1.2 is the way to go. 1-2 glitches and boots everytime.
Rgh2 install with falcon are a pain in the arse.

I had mistake in point E
I got Xell to boot, then wrote nand. Not sure why but now the CR doesn't blink green anymore.
I tried to write orignal nand and moved CR to PRG (Bypass) and booted just fine.

checked all points with Multimeter for continuity and seems fine. it has to be soldering right ?

Changed installation to RGH1.2.
but still CR won't flash green. When I program it via NAND-X it flash green during write of timing.
Can it be that its dead ?

Need new pics of install. Also timing file 19-21 shud boot it.

Well, disconnected RGH2 wiring from board, and made new ones for RGH1.2.
I think soldering is fine, tested with multimeter (see below)
The CR gets power, the red is steady. but won't try to glitch (not flashing green)
When i write timing using NANDX i can see the green is on during flash.

What am I missing here?

remove that wire for cap and bridge 2-3

ok, trying to glitch
but no success
What timing should I use for RGH1.2 ? no to much info about this

Thanks mate!

u need to head over to teamx360 but try 12,21, remove cap off of c7r112 and solder to pad

 

[Chura]

Where is that CAP, can't see it.
and where can i get this timers ?
I can't register to X360 , registration are disabled.

post a clear pic of cpu rst point under xclamp looks like a cap is on that point u soldered to

OK, got the time files, non of them make this boot

 

[Chura]

Just to be safe, flashed original and CR to PRG, and i'm booting fine to original.
RGH1.2 is working for every jasper ?

yep fine with every jasper i have done.
cool runner need to be programmed with M-A-T-R-I-X files, try link below.
you will probably need the rgh12-21 xsvf. with the cap open on you cool runner and 2-3 bridged

Do u get a flashing green light at all. Like its trying to glitch

 

[Chura]

Yes, Trying.
What about JP ? closed ?

I leave everything as default on coolrunner. What timing file did u use. Timing file 21 should boot it.

 

[Chura]

Thank guys, I've decided to restart everything, not sure what I did wrong either soldering or bad write.
I removed all cables, reinstalled as RGH1.2, write Xell just to be sure CPU key is fine. write image, CR timing file 21 as suggested.
And Booooom, booting flawless almost immediately every time!

Thank you ppl, I appreciate the patience and helpful tips here, no where like TX
