bbone = Beaglebone Black is on left - OS = Fedora 25 ( 4.10.17-200.fc25.armv7hl)
tinkr = Tinker board is on right - OS = Debian-Linaro (4.4.16-00006-g4431f98-dirty)
The Debian 4.4.16 is the native version provided by ASUS. There are numerous issues with the level of support provided for their board. Primarily due to the maturity of their "device tree" definition.
The "device tree" file is what maps the hardware components for the Linux kernel.
I have since loaded Armbian which has a very solid "device tree" definition implemented with ARMBIAN 5.27, derived from Ubuntu 16.04.2 LTS, and kernel level is currently at Debian version 4.11.3-rockchip.
Yes, the workstation is currently F25, but will move to F26 sometime during the Beta timeframe. The F26 release includes the 2017 u-boot libraries which provide Tinker board support.
The Fedora ARM project has not yet developed a Tinker board package. Sorting through the u-boot, device tree, and kernel build issues to build my own package is my current challenge.
There is a lot of work represented in that single sentence goal
For info: the Tinker board uses the same components as the ASUS Chromebook C201.
