      Not 100% sure how I got into this scenario but I think I accidentally hit the erase button when picking up the display.

      With 12v connected to vin, the DuetWifi powers up fine. On the 7" lcd I get a blank screen - no indication if there is power supplied to the LCD but the DuetWifi board is responding fine.

      I have tried to flash the display driver and get an error when pushing the flash:

      When I had the panel connected to the DuetWifi before things went strange all I saw in the status on the top-right was Connecting. I have a 4 conductor wire ( http://openbuildspartstore.com/wire-cable-by-the-foot/ ) between the boards. All of the connectors are good. I get the same behavior with usb plugged into the panel board from my macbook.

      Any ideas?

        Try again with a different usb port or cable. I have one pc that gets verify errors on usb3, but works fine on usb2.

          I suspect either a USB issue (see above) or a power issue. Many USB ports can't provide enough power for the 7" panel. Try disconnecting the control board from the display, then try to program it.

            So it was a usb cable issue. I was using the usb cable provided when I bought the boards - switched to another one and all is well. Flash was fine, display is running again so yay!

            I do have a thought on a minor board layout change. I accidentally hit the erase button while trying to remove the usb cable. Would it make sense for that button be moved in a future rev? Maybe a tiny button closer to D3 or something? ( eg something to make it less likely to accidentally trigger / bump ). Just a thought!
