    I have the board connecting over Ethernet, Wifi and USB. I get the web interface and can also log in with ssh using udooer, udooer.

    The web configuration gives "Unexpected error during keyboard layout change. Please, try again." regardless of whether I set the keyboard to gb or leave it as the default us.

    The composite USB device includes a CDC serial port but Win7 doesn't have a driver, where can I find the driver for that? Tried here http://www.udoo.org/tutorial/connecting-via-serial-cable/?portfolioID=1394 but seems to be wrong VID.

    The web interface shows "Remote desktop active" but I couldn't connect to it with TightVNC until I ran

    vncserver :1 -geometry 800x600 -depth 24

    It then just gives a completely grey screen with a cursor.

    Hi! I'm experiencing similar issues.

    The web configuration gives "Unexpected error during keyboard layout change. Please, try again."
    I'm getting the same error. I had to unplug the Neo while it was powered up once during install to get the USB device to be recognized. I was worried I had already corrupted the SD card, but this is an oddly specific error.

    Perhaps the partition is write protected, but no, I can create files over SSH. Next thought would be that the config file may have ownership issues related to the web app. I haven't dug in to find that bit yet. At that point I'll probably just set the field manually.

    One bit of good news here; if I do not enter a wifi password another error is generated that the password is incorrect. So the Wifi credentials may actually be getting saved.


    The web interface shows "Remote desktop active" but I couldn't connect to it with TightVNC until I ran
    vncserver :1 -geometry 800x600 -depth 24

    I hadn't gotten that far. I was going to adapt the instructions from https://www.digitalocean.com/community/tutorials/how-to-setup-vnc-for-ubuntu-12
    I've gotten the grey screen on VNC connections in the past. Best guess would be to reboot and try this on vncserver :0 to see if one is already running. If so, check the config files to find out the geometry. There's not a section in the manual for VNC yet, so starting from scratch (the digitalocean article) may not be a horrible idea.

    If anyone does have a more specific tutorial for the NEO that would be great to post!

    This looks like it may be the Arduino showing up as a device. From what I found, in order to program the Arduino from the computer it would have to be forwarded. The M4 communicates internally, I don't think it's compatible with programming over the USB. This may be bug, or an artifact of the fact that an OTG can be connected to create another USB port. I really don't know.

    • If it is possible to program over the USB sign me up.
    • If there could be an IDE built into the web UI, that would be beyond amazing.

    Thanks everybody for pointing this bug out. It will be fixed soon.
    For what concerns tutorials generally speaking, the first one have been made by Christian Edge, a UDOOer. You can find them here and here

    Dear Josh, anyway if you say "Ok" when you get the message ""Unexpected error during keyboard layout change. Please, try again." you'll have to reboot and then it will work.

    Dear nophead and josh,
    you speak about a gray screen with a cursor in VNC.
    Have you tried just waiting? It works for me if I wait circa 5-10 seconds.

    The problem was caused by following the tutorial that says start vncserver and to use a port number when connecting. That gives a grey screen forever. If one connects without a port number it works after a couple of seconds. xvnc is already running.

    Hi there nophead,
    I didn't understand what you're talking about. When I open VNC Viewer, before connecting I enter the port I'm going to connect, then I enter my password (udooer) then it just connects. What doesn't work on your side?

    I don't think that existed when I got my Neo, did it? All the pictures in that section are broken at the moment.

    Dear nophead,
    it all depends on when you got your Neo :)
    The video tutorial exists since Friday, and the written tutorial exists since before but the part about VNC exists since Friday.
