    After one Year... you've released a new Android Version 4.4

    The Android 4.2 was working fine... but you can't upload Arduino Sketches from external MAC OSX Computer.

    Now you've fixed this upload bug with Android 4.4 but... now you have mass Performance Bugs und Audio Bugs.

    The whole system is hanging from time to time for ~5 seconds and now you have anouing audio clicks every 8 seconds. You can not hear sound on the external Audio Jack on the UDOO Board (only HDMI Out, also you've selected external Audio port... you will still hear only sound over HDMI).

    And the USB OTG Port is disabled everytime you boot with Android 4.4 (was working with Android 4.2)

    Also you can only upload Arduino Sketches with the the J22 J2 Reset trick... this is also still a bug (tested with patched bossac file, also not working).

    All in all... not usable. What you did the last 12 month eh?

    After a reboot the performance issues are gone. And only after a reboot the external audio port is working. You can not switch it without a reboot.

    Also its not possible to upload Arduino Sketches from an external Mac. You have to use the J22 + J2 (reset both fast). The patched bossac file is not working, only the original Arduino bossac file (Mac OSX Arduino 1.5.5) is working with the J22 + J2 trick (annoying).

    You can not use the UDDO Board with Arduino IDE 1.6.4 (Board: Arduino DUE is not available)

    Also Android Settings: USB OTG Debugging Port enabled (after each reboot its: disbaled). You have to enabled it after each reboot, also annoying).

    Power OFF Button with Android is still not working!

    Hi Halloween,
    to programm UDOO with an external computer you have to use the USB OTG. In the previous version - Android 4.2. - the communication between the USB OTG port and the external computer was checked even after reboot, but actually that communication between USB OTG and external PC was lost after the reboot. Now you don't see it checked anymore just because we corrected it: you don't see it checked because it's not, as it wasn't in the previous release.
