Ubuntu Linux 16.04 LTS Preview Image 4 with GUI and Linux 4.14.3

No comments

Overview

After weeks of hard work, we are finally able to release preview image 4 based on Ubuntu 16.04 LTS with the latest mainline Linux 4.14.3 and u-boot with some out-of-tree patches. The u-boot is based on the latest 2017-11 release due to upstreaming work by Neil Armstrong from our partner BayLibre. The image is designed for >4GB SD cards at the moment. eMMC has not been tested (and definitely will not work). Support for eMMC will come on the next version.

Changes from Preview Release 3

  • Upgraded Linux kernel from 4.13.3 to 4.14.3
  • Switched from Amlogic’s u-boot to mainline u-boot 2017-11
  • Added automatic filesystem resize on boot to expand to full MicroSD card size
  • Added ssh host key regeneration on boot
  • Disabled CVBS in the device tree to reduce the occurance of HDMI resolution-unsupported/no-video
  • Utilize the latest zstd compression feature of BTRFS for faster read/write
  • Increase MicroSD card bus speed
  • Faster 2D performance
  • Added a bunch of WiFi and Bluetooth drivers so USB based dongles should all be supported

Outstanding/Known Bugs

  • SSH is enabled and there’s a default password for the libre user
  • OpenGL ES 2.0 is not enabled since performance of xf86-arm-soc hinders the GPU performance
  • There may be an issue with ethernet PHY
  • Kernel and other packages need to be deb’ed
  • Missing 4K support in the mainline kernel
