Here are excerpts from the information I sent Nick at the end of winter.
Simply run the image from the external media (in multi-boot mode, as Arabian), the system will start the test with the output to the monitor\TV.
Yes, I picked the image with the kernel from BUILDROOT 4.9.76 20180211. I have the same problem with kernel build when you enable this option. Therefore, to control the system in the image with the kernel 4.9.76 have to use the UART console or connect via SSH. Incidentally. look my way Armbian (MATE GUI\XFCE) with kernel 4.9.76. After initial setup Armbian via SSH, the system works fine from GUI. In the GSTplay image with kernel 3.14, you can control the system from the keyboard. To do this, turn off the USB keyboard before turning on the VIM power. To turn the power on (start system) and after a test video , to connect a USB keyboard to VIM. Or you can start the system with a connected keyboard, and then (after system startup) disconnect the USB keyboard and plug again. After these steps, you can control the system from the keyboard as usual. By the way, the images have a MC and it can be used to quickly manage and edit files. The main conclusion that I made from the work of these images - to play full - screen video on s912-does not require libMali. There is enough hardware support for decoding. I am now learning to collect KODI without using libMali . I am interested to try how KODI will work on s912 without libMali (libhibris) with hardware decoding. Then we can collect KODI for Armbian\LE for s912 without the use libhibris (using the aarch64 mode).
This is a theme with details of using this system on other TV boxes.
