As a young engineer, I first understood the importance of good documentation thanks to an incomplete Holtek MCU datasheet that made us waste weeks of development, and the value open source software thanks to Sigma Designs’ SDK that was full of binary blobs with our applications often crashing inside those, leading to software development delays, especially since we had access to limited support. More recently, if you ever worked with the most popular Chinese processors found in ARM Linux development board, usually made by Allwinner, Amlogic, or Rockchip, you must have gone through roadblocks due to a lack of documentation and software support. So far, Allwinner is purely relying on linux-sunxi community and “leaks” of their documentation and SDKs, while Amlogic has had their “open linux” microsite for several years, but you won’t find complete documentation like technical reference manual, schematics, and part of the source code requires you to […]
How to Install RKMC “Kodi for Rockchip” App in your TV Box
I’ve started playing with Vorke Z3, an Android 6.0 TV box based on Rockchip RK3399 , and saying that Kodi 17.3 – installed from the Google Play Store – is not working so well is an understatement. The other Rockchip TV boxes I’ve recently reviewed with Android 6.0.1 such as Yundoo Y8 and A95X R2 are all using TVMC, a fork of Kodi 16.1 specifically designed for Rockchip devices. However, there’s no source code for that app, but a Rockchip engineer is maintaining his own fork of Kodi, with the code and some binaries libraries released on Github. The project is called RKMC. I did install the app, but I misunderstood part of the instructions at first, and the device would not boot anymore. I lost many hours of work, as I had to reflash the firmware. So I’ll show how I installed it in Vorke Z3 TV box. You […]
MQMaker MiQi & ASUS Tinker Boards Get Linux 4.11 with 3D Graphics Acceleration
One day after the release of Linux 4.11, developer “Miouyouyou” has released Linux 4.11 for Rockchip RK3288 platforms such as MQMaker MiQi and ASUS Tinker boards with some patchsets for ARM Mali r16p0 kernel drivers, ARM fbdev, and to improve performance. The kernel has been tested with the Mali User-space r12p0 drivers for fbdev and wayland written for Firefly-RK3288, and some OpenGL ES 3.1/3.2 samples could successfully run on the board. 3D graphics acceleration does not work in X11 however. Miouyouyou also plans to add support for Rockchip VPU code, as well as ARM gator, and document how to use ARM DS-5 Streamline for OpenGL ES 2.x/3.x debugging. If you have a MiQi or Tinker board running Debian, you can try the kernel by adding beta.armbian.com Debian repository to your apt source file, and installing the following packages:

apt install linux-image-dev-rockchip linux-headers-dev-rockchip linux-dtb-dev-miqi |

Rockchip Introduces Three Tablet SoCs: RK3126C, RK3326, RK3366, and RK3368H Processor for 2-in-1 Laptops
Rockchip has launched four more processors at the Hong Kong Electronics Fair 2017, with three SoCs specifically targeting tablets namely RK3126C, RK3326 and RK3366, and one SoC, RK3368H modified from RK3368, designed to provide a lower cost alternative to RK3288 and RK3399 for 2-in-1 hybrid laptops and tablets. The company only provided limited information with regards to the tablet SoCs specifications: RK3126C quad core processor supporting 1080p video decoding and HD (720p?) displays for entry-level tablets RK3326 quad core ARM Cortex A35 processor with a quad core Mali GPU, DDR3/LPDDR memory interface, 1080p60 H.264, MPEG-4/-2 video decoding, and 1080p30 H.264 video encoding RK3366 quad core ARM Cortex A53 processor with a quad core Mali GPU, DDR3/LPDDR memory interface, USB 3.0 interface, and 4K H.265 video decoding All three processors will be running Android 7.1. I could not find any tablets based on the processor yet, so we may have to […]
LibreELEC is Now Running on Ugoos UT3+ (Rockchip RK3288) TV Box
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 […]
