@craigjb@fosstodon.org Which tool created those waveforms? (And yes, you can't assume that all DP sources and sinks rigorously conform to that kind of stuff. The HDMI cert requirements are much stricter.)

@tom_verbeure@mastodon.social these are on a Saleae MSO with their software and a custom HLA (partial) for the DP AUX protocol. I was using ngscopeclient too, but the 20 channels of logic analyzer inputs are so handy for general troubleshooting on an FPGA. I’ll have both together soon as I bring up the main link. I just doubled the timeout to 600 us for now. No sense being a stickler about the spec I guess. Compatibility testing for commercial DP sources must be _fun_.
