PLEASE BE AWARE THAT THIS CORONA RGH METHOD IS NOT TOO RELIABLE AND DOES NOT GLITCH AT THE BEST SPEEDS. THE HACK IS MADE AVAILABLE SO YOU CAN HAVE A PLAY WITH THIS YOURSELF AND SEE WHAT RESULTS YOU CAN ACHIEVE.
THIS IS WHY WE DESIGNED THE COOLRUNNER 3, IT HAS BEEN FINE TUNED USING A MUCH MORE ADVANCED DESIGN AND GLITCHES VERY RELIABLY AND VERY FAST. WE DO NOT OFFER ANY GUARANTEES OR SUPPORT WITH THIS CORONA METHOD.
To get this working on CoolRunner Rev A B or C you simply have to add a 48.000MHz crystal.
If you have Rev A or Rev B remember to remove C15.
It's a bit cheap and cheerful but here it is anyway.
The crystal has to be good quality - not some cheap crappy one as it will not work.
These work very well:
48.000MHz crystal wiring to the CoolRunner:
PIN 1,4 to 3v3
PIN 2 to GND
PIN 3 to B
We have included 6 files with different timings
The most important point is the CPU_RST - this will make the difference between a 30 second glitch and a 30 minute glitch.
You may want to try using the CPU RESET CLEANER addon that we released - it works very well with RGH1 and RGH2.
We also recommend you try the different wire layouts as per the original CoolRunner instructions.
CoolRunner 3 is in production right now - you will get to see how Slim glitching should be done
Thanks to GliGli & Tiros for the original RGH exploit.
