    Hi guys,

    I'd like to ask about this peculiarity: my UDOO Neo Extended freezes after a random time: 5 minutes to few hours. Nothing is in the syslog neither in errorlog, it simply stops responding on pings or web access and doesn't recover until manual reset.

    Running latest UDOObuntu 2.2.0 (Ubuntu 14.04 LTS) release, having Arduino sketch copying data between the two serial lines to give Python access to Arduino UNO connector @ 115.2 kBaud as a start-up script, no SW packages apart from apt-get update/upgrade.

    I tried to power the board with two different PSs (12V PSU or 5V in microUSB), both have the same behavior.

    What can I do with that? Thanks for your insight!

    There is only a small serial buffer on the Neo Arduino side, so be sure your pythons script is reading the data as soon as Neo Arduino is sending it.

    Se also the serial https://www.udoo.org/docs-neo/Arduino_M4_Processor/Arduino_differences.html
