How to Resize Android’s Internal Storage Partition in Rockchip Devices

I installed Light Biz OS firmware on GeekBox yesterday, but I’ve quickly realized many applications such as Gimp Inkscape would not install due to the small 1.94GB “internal partition”, so I asked how to increase the partition size in GeekBox forums last evening, and got an answer overnight from “dewet”. The good news is that it worked so I’ll share the steps I followed in a computer running Ubuntu 14.04. It might also be possible to perform the same tasks within a Windows machine with Rorkchip’s Factory tools First let’s download the utils with relevant scripts and binaries:

Now copy your device or board’s firmware file “update.img” to the working directory, and unpack it:

The output should look like:

The files will be in the “output” directory. For our purpose “parameter” file, and especially the last line (CMDLINE) where we will want to adjust the userdata partition […]

Android 5.1 Firmware for Rockchip RK3288 TV Boxes by Ugoos and CloudNetgo

There are times when you are happy to have spend a little extra for a device to get better software support, and while most Rockchip RK3288 TV boxes are still running Android 4.4, a few companies have been porting Android 5.1 Lollipop to their products, including Ugoos and CloudNetgo. Ugoos has been working on Android 5.1 for RK3288 for while, releasing several beta firmware in the process, and the latest beta firmware (3.0.2b) includes Light Biz OS (aka Multiwindow) support to provide a better Android desktop experience, OTA firmware updates, and several bug fixes. One new small-yet-neat option is to customize the use of the power LED on the devices (WiFi, Ethernet, IR, CPU usage….), or if you don’t like it turn it off. The Android 5.1.1 firmware (still beta) is available for three devices: Beta Firmware v 3.0.2  for Ugoos UT3 – See Ugoos UT3 specs Beta Firmware v […]

Linux 4.3 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.3 last week-end: So it *felt* like the last week of the rc series was busy, to the point where I got a bit worried about the release. But doing the actual numbers shows that that really was just my subjective feeling, probably due to the kernel summit and travel back home from Korea. It wasn’t actually a particularly busy week, it’s just that the pull requests were more noticeable in the last couple of days. We had a network update and a late fix for a x86 vm86 mode bug introduced by the vm86 cleanups, but other than that it’s just a collection of various small one-liners all over. Ok, the vm86 mode thing was a one-liner too, it was just slightly more nerve-wracking because it looked scarier than it was before people (Andy) figured out what was going on. The changes from rc7 […]

Rockchip Light Biz OS Improves Android’s Desktop Experience

Android is great for consuming content, but if you’ve ever tried to use it to create content, it can be an hassle, as copy / paste is hard to use, shortcuts aren’t available, and overall the operating system and apps are not designed to work well with a mouse and keyboard. Remix OS is one of the solutions, and Rockchip has been working on improving Android as a desktop replacement for while, starting with multi-window support, and recently they showcased “Light Work OS“. But yesterday Charbax, of ARMDevices.net, uploaded two new videos showing Rockchip Light Biz OS in action, probably renamed from Light Work OS shown a few months ago. The first video is the “official” Light Biz OS video released by Rockchip, which shows the main features including: Based on Android 5.1 with CTS certification Light Biz OS features can be enabled/disabled in Android settings using the Multi-window option […]

Reeman Playmate is a Robot for Kids Based on Rockchip RK3288 SoC

Rockchip processors are usually found in tablets and TV boxes, but one Shenzhen based company called Reeman has designed Playmate robot for kids powered by Rockchip RK3288 processor, which can take picture, sing, dance, tell stories, be used for video chat, and goes to recharge itself automatically when the batteries are low. The Rockchip processor takes care of a 10.1″ touchscreen display, stereo microphones, speakers, camera, and artificial intelligence which recognizes Chinese and to a lesser extend English language, and take relevant actions, while the motors and sensors are managed by a few ARM Cortex M3 micro-controllers. The robot is still in development, and the company is working on adding a 3D camera to recognize objects, which will allow the robot to find its charging dock among other things. The Android 4.4 robot will be available for 2,999 RMB (~$473) in Q1 2016 in China. Charbax filmed the robot at […]
