    Hi there,

    I have tried to boot the UDOO NEO for several times using a Samsung 32 GB Micro SD Card.

    I have prepared it following the installation guideline on the website using dd and copying the image to the Card.

    I am running Mac OS 10.10.5, Yosemite.

    My Questions:
    - What should happen when the UDOO boots (blinking LED, ...)?
    - Does it boot without Keyboard, Mouse, ... connected?
    - How can I check if the SD card is properly prepared (HEX Editor, ...)?
    - What else could I do to check the system (USB connection as described does not work either)?

    Thx
    Kay

    Dear kay,
    could you tell us exactly what doesn't work on your side?
    To answer your questions:
    3 and 1) the best way to know if your Micro SD is properly prepared is to try if it boots; when the board boots the green LED blinks, telling you that the power supply is ok. The RED LED, the one in the middle, will blink too to show you the Neois working;
    2) it boots with or without keyboard, mouse etc. If you are powering it up via Micro USB you need to power it up without attaching anything else, like the keyboard or the mouse;
    4) USB Direct Connection works fine, just take a look at this video:

    Take a look also to the related topic in the docs of UDOO Neo:
    http://www.udoo.org/docs-neo/Basic_Setup/Usb_Direct_Connection.html
    And tell us what doesn't work for you!

    Hi Kay & Andrea,

    I appear to have the same problem. When connected by USB or DC Power all I have is a solid green light. I have flashed the image twice to the SD Card. Using a 64gb Kingston.

    About to try with a 32gb card to see if its any different.

    Well, turns out I was writing the img to the partition not the card itself! All good here now

    I'm having the same problem. I followed the instructions on http://www.udoo.org/get-started-neo/ (Use UDOO NEO as an headless IoT device with a SanDisk Ultra 8GB card). Installed the Usb Direct Connection drivers on my Mac and connected the UDOO NEO to my MacBook with a Micro-USB cable. The green light keeps continuously on and no blinking or red light.

    Any help would be appreciated.

    I see what the problem was... I also wrote to the partition instead of to the disk... :oops:

    I changed:

    sudo dd bs=1m if=/Users/erje/Downloads/UDOObuntu_neo_basicks_v2.0beta3.img of=/dev/disk2s1

    to:

    sudo dd bs=1m if=/Users/erje/Downloads/UDOObuntu_neo_basicks_v2.0beta3.img of=/dev/disk2

    And voila!
