Well, given the extreme fragility of the uHDMI and uUSB connectors used with stiff adaptors, that seems like a recipe for tearing them out (one key/mon uUSB already tore off the board and I wasn't pushing the adapter cable hard). Connecting the hdmi after booting, one board has frozen text output on the uHDMI and the other nothing, so I would say that my uHDMI output seems nonfunctional in the stock release out of the box, and you have to use ssh and vnc.

Sometimes it requires several retries.
I'm using an HDMI switcher and an USB switcher. (selecting another channel during booting)
Please consider using these items.
They are very convenient.

We are working on the HDMI issue, agree that it should boot out of the box without issues. This is a high priority.

Are you saying one of the connectors on the Parallella broke? Can you post a picture? We probably have 1000 inserts at this point and haven't seen a problem, but if there is a problem we need to fix it quickly!

Thanks,

I don't think this is a HDMI issue, because it works very stable (including HDMI and USB devices) once it boots correctly.
Probably this is a boot sequence issue.

moving broken connector discussion to a new thread.

I will try using an hdmi/usb switcher for testing, tho it drives my costs for supplying clusters to the researchers up by almost $200 8-<
