RGH Doubt about CR Rev. C

[marcosgue]

First sorry for my bad english.

I have a big doubt about this step to make RGH 2.0

I leave 1, 2 and 3 opened. Then i check with my multimeter and i have continuity in all points. then close it do not have sense... the three points are already connected between then.

I try that becaus i try to make a RGH 2.0 in a Jasper BB 512Mb and that never glitch using the points closed even if i use 1-2 closed or 2-3 closed...

Then i put a 10Ohm resistor in the point D like in the CoolRunner Rev B, and it work 100% fine!!!

If somebody can explain this to me please do it.

Thanks for everything.

You MUST post images if you require assistance.

These jumpers change capacitor values (add or subtract them) from the circuit on the CR. That is why you get continuity on all points. It is entirely possible that you had a strange Jasper that doesn't like the standard configuration.

But like Martin says, pics are a must!
