Open Bench Logic Sniffer / Re: Capturing problems
I'm using 0.9.7 software and firmware v2.5!
The capture seems to 'happen', but it's like every channel is connected to ground. I cant even capture a static HIGH - unless I use the 200MHz sampling rate.

Open Bench Logic Sniffer / Capturing problems
I have troubles capturing signals with my logic sniffer.
The problem is following:
I was encountering this problem while capturing i2c signals so I have set up a PWM signal with ~10kHz frequency to test the sniffer. When i choose 200MHz sampling rate it seems to capture everything properly, so now, when I choose a lower rate it MIGHT capture just once after I reduced the rate from 200MHz. To capture again at a lower rate I have to set it to 200MHz again first, then capture and then reducing again the sampling rate and capture.
The lower the sampling rate the lower the chance that it captures anything.
And thats not random, the ONLY chance is to capture at 200MHz and then ONCE at a lower rate.
I hope somebody knows how to fix this.
