How to Unbrick MeegoPad T01 (Intel Atom Z3735F) HDMI TV Stick

When you use one of the Intel Atom Z3735F mini PCs, there’s very little chance to brick it as long as you use the pre-installed operating systems. But if you play around with the BIOS, or use one of the recent dual boot firmware that re-flash the BIOS when you switch OS, there’s a real possibility to completely brick your device. Ian Morrison (Linuxium) and Deadhp1 posted separate instructions to flash the BIOS and recover their devices. Both bricked MeegoPad T01, and deadhp1 used CH341a USB programmer which only supports 3.3V/5V, while the SPI flash on T01 only support 1.8V. It worked for him, but it could potentially fry the flash. So it’s probably better to with Ian’s solution involving EZP_XPro USB Programmer and some SOIC8 Test Clips. Once you get the hardware, you’ll need to download on install EZP XPro Flash 1.4 on a Windows PC. Now follow the […]

lowRISC Open Source SoC Project Announces its First Release with Tutorials for Simulators and Zedboard

lowRISC project aims to produce a completely open-source SoC (System-on-Chip) based on the 64-bit RISC-V instruction set architecture, as well as a corresponding development board, thus eventually producing a fully open hardware systems. The project has now announced its first release “tagged memory preview release” with a tutorial explaining how this has all been designed, and how to run simulations with software tools, or FPGA boards such as Zedboard. The project is based on Rocket core, written in Chisel language by the RISC-V team at UC Berkeley. Chisel can generate code to produce a cycle-accurate C++ emulator, Verilog optimised for FPGAs or Verilog for use in an ASIC flow.If you want to try it out, you’ll need a Linux machine, preferably running Ubuntu 14.04 64-bit, with GNU GCC 4.8 installed, and follow the tutorial in order to get the source code, and build tools such as riscv64-unknown-elf-gcc compiler, and […]

How to Program STMicro STM8S $1 Board in Linux

In January, I discovered there was such thing as a one dollar development board based on STMicro STM8S103F3P6 8-bit MCU with 1KB SRAM, 8KB flash, and 640 bytes EEPROM, some GPIOs as well as I2C, UART, SPI, ADC, and PWM signals. Links to documentation and source code were provided, but development tools were only Windows based. However, one of my reader informed me SDCC (Small Devices C Compiler) supported STM8, and development in Linux should be feasible. So I decided to buy the board on eBay for $1.62, as well as an ST_link V2 programmer for STM8 / STM32 for $4.52 in order to flash the firmware. The board came pretty quickly, i.e. within 2 to 3 weeks. But due to a lost package, the programmer took nearly 3 months to reach me, as the seller had to re-send after I failed to receive it within 2 months. It comes […]

How to Easily Install Popular Add-ons in Kodi

You can use Kodi to watch videos locally, but various add-ons can be installed to also access videos online, but finding and installing add-ons might be a pain if you don’t know where to start. TVaddons.co, previously known as XBMCHUB, is providing add-ons allowing to do just that, more or less legally [Update: You may want to read comments for details about the legality of these add-ons], as well as a method to install a bunch of popular add-ons in a few clicks. These add-ons are completely unrelated to Kodi project, and have been developed and maintained by third parties. The installation requires Fusion Installer and Config Wizard with detailed instructions available there with every screenshot, which makes it more complicated than it really is, but it can be summarized as follows: Go to System->File Manager, and click Add source You’ll get the following pop-up window, where you need to […]

Xiaomi Mi Box Mini Review

After showing pictures of Xiami Mi Box Mini, it’s now time for a “review”, but a bit different from my other reviews, as Xiaomi tiny media player is much different. First the firmware is in Chinese only, and there’s only one external port HDMI output. So first I’ll show the user interface is Chinese, then explain how you can install your own Android apps, and finally run some benchmark to evaluates Mediatek MT8568, Wi-Fi and storage performance. Xiaomi Mi Box Mini Setup and Chinese User Interface The device is super small, but in my case it was almost too big, as it takes enough space to potentially cause problems with the adjacent plug. This little issue will of course depend on your power extension. You then need to connect the 1.5 meter HDMI cable, which should be long enough for most setups, and you’ll see some guide asking you to […]

Cubieboard 4 Ubuntu Review – Setup, Usability, and Performance

Cubieboard4 is a development board powered by Allwinner A80 octa-core processor with 2GB RAM and 16GB eMMC. I’ve already shown how to get started with the board using the pre-installed Android 4.4 image, and run some benchmarks in Android, so now it’s time to check out the Ubuntu Linaro 14.04 image provided by CubieTech. I’ll show how to install and setup Ubuntu 14.04 on the board using a micro SD card, run desktop applications like Chromium, Libre Office, and son on on the board, and complete the review with some Linux benchmarks. Setting up Ubuntu on Cubieboard4 Firmware images for Cubiebord4 can be downloaded @ http://dl.cubieboard.org/model/cc-a80/Image/. Currently Android 4.4, Debian server, Ubuntu Linaro server, and Ubuntu Linaro desktop with LXDE desktop environment. That’s the latter I’ll use for the experiment, and two images are available: linaro-desktop-cb4-card-hdmi-v0.4.img.7z – Bootable image from micro SD card linaro-desktop-cb4-emmc-hdmi-v0.4.img.7z – Installation image to eMMC to […]

How to Install Ubuntu 14.04 on Acer Aspire E5 Laptop

I’ve been owning an Acer Aspire One D255E netbook with a 10″ display, an Intel Atom N455 processor and 1GB RAM that served me well during my travels, but as I’ve become older and less patient, I felt I needed to upgrade it. I planned to spend around 10,000 Baht (~$300), wanted a 14″ display, one of the low power CPU such as Intel Bay Trail-M or AMD Mullins / Beema processors, at least 500GB storage, 4GB RAM, and the ability to install Ubuntu. Finally, after going through several products at my local shop, I had to chose between Acer Aspire E5-411-P3CL with a 7.5W TDP Intel Atom N3540 and Acer Aspire E5-421G-45L0 with a 15W TDP AMD A4-6210 processor that both sell for 11,900 Baht ($365). Despite my preference for processor with lower TDP, I still went with the AMD system, since the performance is a little better, the […]

Cubieboard4 (CC-A80) Unboxing and Getting Started Guide

A few samples of Cubieboard4 board may have been available in China in October 2014, but Cubietech only officially launched their Allwinner A80 development board about ten days ago, and you can buy it for $125 + shipping on sites like R0ck.me, Eleduino, Seeed Studio, and many other distributors. The company decided to send a sample for evaluation, and today I’ll start with a post showing some pictures of the kit, and explaining how to get started with assembly and first boot. Cubieboard 4 Pictures I received the board within two days after the company told me they would send a sample, as they used DHL. I also had to pay a bit of import tax and DHL’s handling fee. There should be CC-A80 box with the board and accessories, a white box for the power supply, and a power cord. There’s quite a few items to play with… The […]
