TERES-I Open Source Hardware Laptop has new experimental Armbian Mainline Linux image for download

TERES

We uploaded few days ago Armbian experimental mainline linux image for TERES-I on our ftp.

There are still few known issues which we work on, but we wanted to upload this experimental image so other people can start playing with.

What is new?

  • eMMC now run x3 times faster which improves the overall user experience.
  • OpenGL with LIMA

Known issues:

  • Automatically turns on upon applying power via the PWR_JACK, we need time to patch mainline uboot
  • No sleep or suspend, WIP.
  • Bluetooth not working out-of-the-box – fixed in Olimex release if you install the package
    ftp://staging.olimex.com/Allwinner_Images/A64-Teres/linux/armbian_experimental/teres-bluetooth_0.2-1_arm64_armbian.deb
    with command:

    dpkg -i teres-bluetooth_0.2-1_arm64_armbian.deb

  • Keyboard LEDs not working – fixed in Olimex release – install the package

    ftp://staging.olimex.com/Allwinner_Images/A64-Teres/linux/armbian_experimental/teres1-ledctrl_0.1-1_armbian_arm64.deb

    with command:

    dpkg -i teres1-ledctrl_0.1-1_armbian_arm64.deb

  • The LCD brightness is low by default (20%) – fixed in Olimex release – to increase it type in the console

    echo 9 > /sys/class/backlight/backlight/brightness

  • no video player acceleration, to be fixed in the next release planned for 22.02.2019

 

TERES-I has patch and can work with both LCD and HDMI together

This picture was sent by Roman Beránek from Prusa Research.

He is using two displays one LCD and another HDMI with different resolution.

His patch is being reviewing now.

We also are working on this dual display use for some time, but we want to may dynamically switch between LCD and HDMI so TERES-I can work with projectors, we are close to release it in new image.
