Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.

Re: Project: HDMI/DVI out for STFM
Doing nothing is good, it means it's only reading zeroes (or 1 in medium). Like me, your machine works with the mod for some unknown reason.

I removed the cap I added and this is what happens to the video...
( still get nothing in that program with the cap removed)
Video is fine with the cap.

- The latching behaviour is only level-sensitive, so high-frequency noise around the transitions shouldn't cause glitches
- The values that are being read seem very non-random, in the sense that either reads the whole word perfectly, or else it reads it with 8-12 wrong bits. It never reads just one wrong bit here and there. The pattern of bits is also very uniform, e.g. 0xb479 comes up a lot (see video and screenshot posted by Icky above)
- The reason I don't think it's clock related is that both Icky and Troed have the same behaviour, and Troed is using a totally different clock.
Could you get your program to output in binary instead ? Then be easier for people to see if any particular bit(s) are having issues...

Re: Project: HDMI/DVI out for STFM
That's more good evidence that the register read problem isn't related to clock stability
The line of Xs is the value in binary.

Re: Project: HDMI/DVI out for STFM
So what motherboard revisions are people using then ?
This is mine..
Different boards tend to have different "faults".
Is everyone's HDMI board exactly like the one I have ?

Re: Project: HDMI/DVI out for STFM
Mine's a C103414-001 rev 1.1.
The HDMI boards are all the same, unless I'm misremembering (V4).
