How to Flash Rockchip RK3066 / RK3188 Firmware in Linux

Rockchip provides 2 tools to update the flash: RkBatchTool – Used to upgrade firmware with a single file RkAndroidTool – Used to flash the NAND flash with image corresponding to particular partition, e.g. system.img. kernel.img, boot.img. recovery.img. etc… One problem is that the company only provides these tools for Windows, so if you’re using a Linux based operating systems, you’d have to run a Windows XP or 7 virtual machine in VirtualBox or VMWare, which is an inconvenience, and requires a license in theory. To work around this issue, I’ve tried to use ReactOS, an open source operating systems compatible with Windows XP, but although the USB drivers appeared to install properly, RKAndroidTool failed to recognized my device (MK908). But a member of Mini PCs community informed me about a tool called RkFlashKit, written in Python and using GTK, that can flash firmware to Rockchip RK3066 and RK3188 devices in […]

iMX6 Rex Open Source Hardware SoM and Baseboard Designed to Teach Schematic and PCB Layout Design

Voipac, a Slovakian manufacturing company, has recently unveiled iMX6 Rex module and iMX6 Rex development baseboard, which have mainly been developed in order to support FEDEVEL Academy Schematic Design and Advanced PCB Layout courses, but can also be used for other purposes. The module is powered by Freescale i.MX6 Dual (Solo and Quad also available on request), and comes with 512MB RAM (upgradeable to 4GB), and up to 32MB SPI flash. The complete hardware will be released under an open source hardware license, but with some caveats as I’ll explain later. iMX6 Rex module specifications (basic configuration): SoC – Freescale iMX6 processor up to 1.2GHz / 2 cores (1 and 4 cores also available) System Memory – 512MB DDR3-1066 (533MHz), up to 4GB Storage – 2MB On board SPI Flash, up to 32MB 10/100/1000 Mbps Ethernet PHY 2 high speed board to board connectors (only one required) with signals for HDMI, […]

Binwalk Utility Helps You Analyze and Reverse-Engineer Firmware Files

Binwalk is a “firmware analysis tool designed for analyzing, reverse engineering and extracting data contained in firmware images”. This tool written in python supports Linux, and somewhat Mac OS X, can scan firmware files for files signature, and can be useful for hacking firmware files, and finding hidden information. Let’s install binwalk first. It’s very easy in a Debian or Ubuntu machine, as you just have to download the package, and run a script for installation:

wget https://binwalk.googlecode.com/files/binwalk-1.2.2-1.tar.gz
tar xzvf binwalk-1.2.2-1.tar.gz
cd binwalk-1.2.2-1/src
sudo ./debian_quick_install.sh

wget https://binwalk.googlecode.com/files/binwalk-1.2.2-1.tar.gz

tar xzvf binwalk-1.2.2-1.tar.gz

cd binwalk-1.2.2-1/src

sudo ./debian_quick_install.sh

If you have another Linux ditributions, it’s just a little more complicated. You still need to download and extract the release package as above, but you’ll have to install the following package depending on the features your need: Minimal installation – python 2.6 or greater, and python-magic To generate entropy plot graphs – python-matplotlib For automated extraction: Packages – mtd-utils zlib1g-dev liblzma-dev gzip bzip2 tar unrar arj p7zip p7zip-full openjdk-6-jdk Build and install […]

ZGPAX S5 Android 4.0 SmartWatch Features a Dual Core Processor, a SIM Card Slot

The newly introduced Samsung Galaxy Gear and Sony SmartWatch all work as a smartphone companion, and have limited use if you don’t carry your smartphone with you. The Samsung watch also requires a recent smartphone running Android 4.3 and supporting Bluetooth Low Energy, which current seriously reduces the list of compatible smartphones. There are already standalone smartwatches in the market that include a SIM card slot, and allow you to make phone calls without a phone such as Z1 watch and WiMe NanoWatch. However, these watches feature low-end hardware with ARM9 processor, so the interface may feel a bit sluggish. ZGPAX S5 smartwatch with its Mediatek MT6577 dual core Cortex A9 processor, and 512 MB RAM, will be much more snappier. It runs Android 4.04 with Google Play Store, and comes with features such as a camera, GPS, as well as Wi-Fi and Bluetooth connectivity. SGPAX S5 Specifications: SoC – […]

$80 SJ1000 Waterproof Sports Camera is a Low Cost Alternative to GoPro Hero Cameras

I’ve recently learned about GoPro action cameras, waterproof cameras with lots of mounting options and a wide angle lense which allows to shot amazing action full HD videos, and the best selling cameras in the world. Since yesterday I wrote about low cost waterproof smartphone, I thought It might be a good idea to write about other waterproof devices, and look at low cost alternatives to the GoPro. The GoPro Hero3 comes in 3 editions: White Edition, Black Edition, and Silver Edition with prices ranging from $199.99 to $399.99. All camera can record @1080p and come with WiFi connectivity. The more expensive model, Gopro Hero3+ Silver Edition, can also record in UHD, and comes with a WiFi remote. The original GoPro still seem to be good values, but if you have a tight budget, SJ1000 action camera (aka F10) offers similar functionalities (1080p30 recording, wide angle, mounting options, waterproofness, but […]

Low Cost Rugged, Waterproof and Dustproof Smartphones Powered by Mediatek Processors

If you need a truly waterproof and dustproof smartphone, the Samsung Galaxy S4 Active, compliant with IP67 standard, is probably the most popular phone with this particular feature. However, the phone sells for nearly $600 on site like Amazon, and it may be nice to have some lower cost options. Today, I’ve come across two smartphones powered by Mediatek dual and quad core SoC that are both compliant with IP67 standard, and although their specs do not match the Galaxy S4 Active, the features found in these phones are still pretty good, and they can be purchased at a much lower price. The smartphones I’ll feature in this post are also rugged, which is not really the case for the Samsung device. IP67 standard? What does that mean in practice? The IP Code, Ingress Protection Rating, aka International Protection Rating, classifies and rates the degree of protection provided against the […]
