Preliminary Version of Ubuntu Running on UG802 mini PC (Rockchip RK3066)

Last week, I wrote a post entitled “Rockchip RK3066/RK30xx Processors Documentation, Source Code and Tools“, where I explained that the kernel source code for RK3066 was released and somebody (AndrewDB) had started working on a port of Ubuntu for the platform. It appears he has been pretty busy, as there has been some progress in the meantime… AndrewDB managed to run Ubuntu on UG802 HDMI Stick. Wifi is starting to work, although there are still some minor issues to resolve. He plans to have a dual-boot Android/Linux ROM available in several weeks for RK3066 based devices such as the UG802 and MK808. Eventually, AndrewDB also intends to release a dual boot ROM Android Jelly Bean + Ubuntu for RK3066 tablets. That’s all the information I have for now. This is still work in progress (See TODO List) and no binary has been released yet.

XBMC for Linux on AllWinner A10 Devices? It Works! (Sort of)

Following the lack of support by AllWinner for the video engine libraries (CedarX), I had more or less given up on hope XBMC for Linux would ever run properly on AllWinner A10/A13 hardware. But recently, I found out some progress had been made using existing libs, and saw the Pengpod Tablet video showing XBMC running in Linux fairly smoothly. So I decided to cross-compile XBMC by following the instructions available at http://linux-sunxi.org/XBMC and trying to run it in Linaro ALIP 12.04 rootfs in my Mele A1000. Finally, I managed to cross-compile XBMC, but the performance was very poor in the GUI (6 to 12 fps) and I was unable to play videos and my serial console was flooded with messages like: [Update: I managed to have XBMC Linux running & playing videos on Mele A1000 by using j1nx image (rootfs + kernel). I would first exhibit the exact same issue I had, but those where fixed: 1. To solve the …

FRAM (Ferroelectric Random Access Memory) and Texas Instruments MSP430FR57xx MCUs

I’ve recently received a complementary book entitled “Texas Instruments FRAM MCUs for DUMMIES” sent by Mouser, that provides technical and practical information about FRAM (Ferroelectric Random Access Memory) – pronounced F-RAM – and Texas Instruments MSP430FR57xx MCU series which makes use of this relatively new type of memory. FRAM is a non-volatile memory with power and write speed & endurance characteristics that almost matches SRAM capabilities, and leave traditional Flash and EEPROM memory in the dust in terms of performance, as you can see from the table and diagram below. At constant speed, FRAM consumes 250x less than Flash/EEPROM. Please note the FRAM write speed also depends on the MCU used, and a MCU @ 8MHz can write the FRAM @ 1400 kBps (Source: TI). However, you won’t see this type of memory in devices like smartphones anytime soon because the maximum size currently manufactured is 1MB, density is higher (130 nm process manufacturing) and the cost is higher than …
