    Could you please re-download the file or verify the md5 of the downloaded file?
    Code:
    $ md5sum udoobuntu-udoo-neo-desktop_4.0beta1.img*
    31c6549afbf47aa142dd5de2949d8045  udoobuntu-udoo-neo-desktop_4.0beta1.img
    a2486b08575fa3e9af99fb8d44f5ddaf  udoobuntu-udoo-neo-desktop_4.0beta1.img.zip
    Everything looks file for me. Maybe I did upload the wrong file, or maybe you flashed an old image..?
    Code:
    $ cat /media/francesco/UDOObuntu/etc/lsb-release
    DISTRIB_ID=Ubuntu
    DISTRIB_RELEASE=18.04
    DISTRIB_CODENAME=bionic
    DISTRIB_DESCRIPTION="Ubuntu 18.04.3 LTS"

    Thank you so much for taking this on! I was recompiling the world to get a recent version of nodejs to work on my Neo. This has saved me countless hours...

    I am using the LVDS 7" panel. Display is working, but the touchscreen is not functioning. Before digging into this, does your kernel support the touchscreen?

    Thanks,
    Stuart

    Thank you kindly Francesco, will be testing it shortly.

    One think: could you please change distribution channel to something more appropiate XIX century?
    Sourceforge (199x ;) is ridded with ads, do not work properly and divert your downloads to Kenya if you're in Europe.

    Uhm, actually I did not test the LVDS7. The kernel should support the touch screen (I can't verify it now), I think there may be something wrong in userspace. I have to dig into that.

    If you know a free hosting where files can be ~1GB each, please tell me. I will re-upload files there. I just want to avoid commercial services like mega.
    BTW yes, I totally (personally) agree that nowadays SF is just crap.

    I did test wifi and it "worked for me" (TM).
    Could you please try to connect to a different access point? (eg. hotspot from your phone)
    Otherwise please post relevant logs to get help.

    Francesco: I'd like to confirm that this release works like charm on my udooneo. Thank you kindly for this. Having recent LTS 18.04 is a crucial for udoo neo longeveity. You gave it 4 years of life :) I appreciate your work on this!!

    I did quick scan about current repos/sites and the only one matching your criteria is a gitlab. They have a limit of 10GB for a repo/artifact. I didnt verify it, but they claim in it in faq/blog entries on their site, since LFS release in 2015. You can have public projects there.

    Hi Francesco,

    I was wondering if there was any details or instructions on what was necessary to build the 18.04 image ?

    Thanks,

    You can use Etcher to flash the image into a SD card or use dd command to flash the img file.

    @Francesco I tried to flash a sketch with Arduino IDE 1.8.9 on local machine and my UDOO NEO but I get Connect failed:

    /home/gorgo/.arduino15/packages/UDOO/tools/gcc-arm-none-eabi/4.9-2014q4-20141203/bin/arm-none-eabi-size -A /tmp/arduino_build_877565/udoo.ino.elf
    Lo sketch usa 116452 byte (22%) dello spazio disponibile per i programmi. Il massimo è 524288 byte.
    /home/gorgo/.arduino15/packages/UDOO/tools/udooclient/1.2/udooclient 192.168.7.2:5152 /tmp/arduino_build_877565/udoo.ino.bin
    Address: 192.168.7.2
    Port: 5152

    Error : Connect Failed
    Error : Connect Failed ​

    Any idea why?

    Plus:
    - I tried with the Arduino Web Editor from the frontend.
    I could upload a sketch even if the log outputs an error eventually:

    Sketch uses 54,708 bytes (10%) of program storage space. Maximum is 524,288 bytes.
    flash: uploading input firmware failed

    In the loop() I only print with Serial.println and a 1000 delay.

    - I noticed that the sketch, once uploaded, doesn't start at boot. There's nothing in /var/opt/m4/ folder even if I know the sketch started (It turns out a led on my pcb).

    - What about A9/M4 Serial connection via ttyMCC? Is there?

    Hi, after flashing the microsd the Neo doesn't show up at 192.168.7.2 address, what should I do?

    Tried reinstalling the 2 drivers for macOS, no success.
    Also, in the desktop environment if I try to connect to a wifi network I don't get any prompt to enter wifi password, and it simply doesn't connect.

    Finally, I don't see a virtual keyboard installed, is it? Because I don't have a USB keyboard and I can't even use the terminal to provide other useful information.
