Trying to find out why i cannot see the tX outputs or CLK signals from the chip on my digital scope when the chip is connected to a monitor thru an HDMI port. I only see 1.8 high levels on each output due probably to the pull-up resistors from the monitor. I tried observing these same outputs from a Gumstix Summit board connected to a display the same way and it had a picture on it but again all I could see when I monitor the lines are 1.8V levels. How can I view the signals?
