In this round of releases, we have:

  • v4.4.13-12-ev3dev-ev3 for EV3.
  • for BeagleBone.
  • v4.4.13-12-ev3dev-rpi for Raspberry Pi 0/1.
  • v4.4.13-12-ev3dev-rpi2 for Raspberry Pi 2/3.

You may notice on the EV3 that the boot logo looks a bit different. This is so that we can display kernel messages on boot to help troubleshoot some issues we have been having with the EV3 locking up on boot. Messages won’t actually be displayed until you upgrade the flash-kernel package to 3.35ev3dev9 and edit /etc/default/flash-kernel to remove the quiet option and run flash-kernel and then reboot.

sudo apt-get update
sudo apt-get install flash-kernel
sudo nano /etc/default/flash-kernel
sudo flash-kernel
sudo reboot


  • Kernel package no longer recommends kernel-common - this should prevent questions about /etc/kernel-img.conf during upgrade
  • Hopefully fixed Wi-Fi regression for devices that use the rtl8192 driver
  • Fixed some issues with EV3 UART sensors - big shout-out to @bmegli for helping with this!
  • Fixed the LEGO NXT Energy Storage driver - thanks @kortschak
  • Got LEGO NXT Temperature sensor working using lego-sensor class - also thanks @kortschak
