Rockchip RK3288 may have launched over two years ago, but the quad core 32-bit processor is still much more powerful than many 64-bit platforms on the market, and ASUS selected the processor for their upcoming – and not officially launched – Tinker Board. The processor was found in several Android TV boxes, but people also installed Linux on the devices, and ported Kodi 14.2 Linux to RK3288 with hardware video decoding back in 2015. The news here is that Omegamoon has recently started working on LibreELEC 8.0 port for RK3288 with a Linux 4.4 kernel, and tested it on Ugoos UT3+ TV box.
Full HD movie playback is said to be smooth, Ethernet, and sound work, but WiFi still needs to be worked on.
Omegamoon has released an update.img firmware which can be flashed with upgrade_tool in Linux, or AndroidTool in Windows, replaces whatever operating system you have on the eMMC flash, and works only on Ugoos UT3+ at this time. If you own another Rockchip RK3288 device, it’s a bit more complicated. First, you need a computer running Linux, make sure you get a working kernel with the right device tree file, and download this tarball with system and kernel images, and somehow manage to boot it up on your device as explained here.
If you want to contribute to the development of LibreELEC on Rockchip RK3288 processor, you can retrieve the code from github, and run the script build_rk3288_ugoos-ut3s.sh to build LibreELEC from source, and generate a flashable firmware image. If you happen to own PopMetal development board, build_rk3288_popmetal.sh script might work, but has not been tested.
Separately, Marc Rissewijck, who worked on the initial Kodi port for RK3288, has also published a Kodi debian package (kodi_v0.2.deb) very recently, so if you have a RK3288 hardware platforms running running Ubuntu or Debian, this might be worth a try. I could find a reference in #linux-rockchip IRC logo, explaining the changes:
<mac-l1> hi guys. just made a first kodi .deb package for vpu/mpp including zerocopy/eglimage to test. can somebody check if it works?<mac-l1> just download http://www.mac-l1.com/kodi/kodi_v0.2.deb and dpkg -i the deb package and then apt-get install -f
If you are like me, and have no clue about MPP, it stands for Media Process Platform, and appears to be a new method to handle video decoding on Rockchip SoCs.
