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
