JTAG R-Jtag Falcon FAN

[mat989]

With HDMI instant RROD 0010. w/o HDMI and USB, NO Green LED. Tried 470 and the other setting...Added more solder and inspected postout continuity and the resistance, 120K-140K. What else... Replaced all wires with same colors but 30AWG Kynar..Not long wires...short ones. Aud_Hack as always... Fixed NAND R/W wires, Here are some photos for the the new wires...



This system used to boot xell with issues yesterday, but not today. The green LED just vanished!

Thnx

If you have nothing useful to say, why bother?! I am not sure what might be missing at all...If you noticed an issue then just feel free to say something useful...

*edit*
more pictures

 

[mat989]

Hopefully this is allowed, but I noticed in a different forum - Can I link to other forums? - that the old RGH J8C1.2 is a good alternative if we did short R8C2...I also noticed some awkward resistors and diodes as if the guy was using the old JTAG methods...Any clues?!

*edit*
Voltage jumper yield same issue...No green LED!

*edit*
Wire thickness, and lengths...what are the optimum choices?

*edit*
Flashed stock nand again, disconnected power from R-JTAG board, the system boots into stock dash w/o issues...let me test again! Yes it booted again w/o issues... So this confirms that the system is clean and healthy...the issue is in the hack or my work...

 

[FJB66]

Pin 2 of J8C1 works well for cpu_rst, I removed R8C2 and bridged it. When I had no green light it was the ribbon cable that had pulled out slightly from the post out qsb, it was not in squarely. While testing I also noticed that the green light would flash even if the cpu_rst point was disconnected

 

[mat989]

Maybe the issue is the ribbon cable itself...I might solder wires in its place...Shall I solder all points or some of them?!

 

[FJB66]

Don't waste your time soldering wires, take off the ribbon cable, clean the connection points with some pcb cleaner and test for continuity with your meter. I doubt its broken, just has a bad connection, pulling it out and reinserting may do the trick.

 

[mat989]

I tried that earlier while inspecting, did not do it. Now I soldered I think Kynar AWG32... Here are some pictures... Now the green LED is blinking...I will do further dip/voltage tests before reporting back...



thnx

 

[mat989]

This is the output for 1.2V, aud_hack, dips 1-6, 7 is always ON...green LED is blinking, and NO RROD. No XELL. Next I will test 1.8V

It should be noted that the green LED was blinking super fast!

*edit*
Now, I will test the default voltage once more and see...later, I might test the system w/o aud_hack...who knows?!

 

[FJB66]

Run your cpu_rst off of the alt point, making the wire as short and straight as possible, I suggest running it just in front of the heatsinks and taping it down. Your falcon should boot with either open or 1.2 volts, with dips 3,4 or 5,its just a matter of finding which works best. On my falcon 1.2v produced the occasional rrod if it didn't glitch in 5 cycles or so, with open no rrod.

 

[mat989]

Default voltage, same as previous tests, the system always RROD 0010 at B0

Next, no aud_hack

 

[FJB66]

If you have been through all dips and voltages then clearly something is wrong with your installation, go back and check everything, making you wires as short as possible.

 

[mat989]

Default voltage, no aud_hack, RROD happned once or twice on the early dips... example of output

1.8V, all lead to RROD after few cycles....

 

[mat989]

And Finally 1.2V, no RROD, and here is a sample of the output...regular JTAG, no aud_hack

Next, shortening the wires, and placing the R-JTAG board in a proper place...perhaps in the area above the audio/video output ports...

 

[FJB66]

You are not listening, if you have been through all settings with no boot your installation is bad. You need to trace and fix the problem, it wont magically work.

 

[mat989]

That's why I said I am going to shorten the wires...

 

[Taijigamer2]

Also make sure wires E and F are well soldered and not bridging.

 

[mat989]

Short wires...1.2V, No RROD...did notice two red ROL sometimes but the system was still on and JR-P was getting data as indicated by the rater output...so I did not power down the system until later on... here is a picture of the R-JTAG dev board

here is some rater output, tried all dips 1-6, and as advised 7 is always ON

The best thing about the 1.2V is the disappearance of the RROD 0010, so I might use an alternative cpu_rst...

*edit*
please bear in mind that yesterday the system was booting xell, but was not optimized properly. And today I cant boot xell at all...
