Hi Neo team, @Andrea Rovai @Francesco I just did a sudo apt-get update and sudo apt-get upgrade Unfortunatly now I cannot access the serial device /dev/ttyMCC anymore without sudo. This also means I cannot use the internal Arduino IDE serial monitor: Error opening serial port '/dev/ttyMCC' (Permission denied) Also my python program that uses the /dev/ttyMCC to communicate with the arduino side stopped working! Error: Permission denied : '/dev/ttyMCC' This all worked perfectly just before the upgrade. Please check the UDOO Neo upgrade!!! I will go back to the original RC1 image
Well to be sure it wasn't me I repeated it: - Flashed SD card with a new image UDOObuntu_neo_v2.0rc1 - Started Arduino IDE, set Board and port. Opened serial monitor, no issues. - Did a sudo apt-get update and sudo apt-get upgrade - Shutdown completely, disconnected power and connected power again to boot. Started Arduino IDE. Opened serial monitor: Permission denied on /dev/ttyMCC !
Looks like there has been some big upgrades made. Duplicated your steps and noticed upgrade of Browser. We can fix access to /dev/ttyMCC with the following: sudo chgrp -f dialout /dev/ttyMCC sudo chmod g+rw /dev/ttyMCC
Checked that, fixed. Please redo apt-get update && apt-get upgrade. Thanks to all and sorry for that, ek5
