GENERAL Falcon RGH

[srt4fun]

So, I found this issue with Falcons and the RGH (with the Diligent C-MOD at least). While the CPU_PLL_Bypass wire is taped to the board it freezes when xell loads. Usually never gets past the "Xell Reloaded" ascii text. Now when I take the tape off and let it hang down a bit it goes straight through and loads up linux from my usb drive. I flash the stock image back on with the C-MOD fully disconnected, and wires still in place; taped=0022 hanging=boot. Tried different gauges of wire, routed it differently, and shortened the wire. All to no effect. Also verified this on 2 separate Falcons. My Zephyr and Jasper didn't do this.....weird, eh?

i seem to be having the exact same problem.
wires taped to board: freezes or 0022.
not taped: console working fine.
did you manage to find a workaround for this?

Yeah, I found a solution. Credit goes to Podger, he gave me the idea. The trick is to route CPU_PLL_BYPASS away from CPU_RST and POST_OUT1 as much as possible. My Falcon will boot 95% of the time in 10 seconds or less. It never takes more than 30 seconds at it's worst. Used 30AWG wire for signal and 24AWG for Power/Ground

Here are a couple pics of my install.

Thats useful to know You seem to have an extra resistor across 2 pins??

I've done 2 Falcons so far and both boot to 13604 RGH within 3-10 secs every time. I must have been very lucky!

ah... i tried routing the cables differently, which didn't work, and came up with a more 'ghetto' workaround, using foam blocks as spacers to keep the cables at a slight distance from the board.

seems to work fine so far, got fsd up and running reliably.

I have tried all this on my jasper, nothing makes any difference.

Nope, the only thing extra is the debug LED. Didn't have any larger 3.3v LEDs around so I used a 603, Pain in the arse to solder it, haha.

Nice, doesn't look ghetto to me...

Yes I had the same problem with a Falcon.

I then routed each wire away from each other. Chose to make cpu_pll_bypass wire as short as possible, so I routed it directly underneath the cooling fan. The cpu_rst I routed on top of the board. I then insulated each wire with shinkable wire tubing.

It now works really well. Boots into dash 13604 within 5-10 secs every time. Only slight problem is that it wont boot via controller, but only via power button. But I can live with that...

So thanks to Podger and srt4fun.

modded another falcon and used awg30 wires this time, no problems at all.
