after building most of the bits together it was time for my first real bootup and test. I noticed that I couldn’t get an IP connection to the OpenROV through the top-side tether, the static IP setup and using Chrome to access the UI. After some testing and debugging I noticed that the middle diode of the top-side tether homeplug adaptor usb board wasn’t lit up (the one that seems to indicate that the 2 homeplug boards know about each other).
Some fiddling around with the Electronic Components (due to go in the acryllic tube) showed that I could get the lights to flicker every now and then but not in a repeatable matter. I did create some arching in the process (had the plus / minus Molex pins coming from the batteries touching…)
Now the situation is as following:
- No diodes working on the Homeplugadaptor on the chassis (2 diodes working on top-side)
- Beaglebone cape is giving me 5V on the 5V marked plus connector, but is giving me 0V on the 3.3V marked plus connector
So my questions ? How can I check if the cape is in good working order ? It seems strange that the 5V pin works, but the 3.3v doesn’t (used all possible combination with ground pin)
If I’ve fried my homeplug adaptor - where in Europe can I get one ?
Other ideas ?
