The initial start of the Raspberry Pi requires the following steps:Install system image to SD cardConnection Configuration Raspberry PiConfigure Remote Control Raspberry PiThe materials to be prepared are as follows:More than 16G high-speed storage SD card one. (Please note that the

(The execution of the preceding three commands takes a long time. Please wait. After execution)
6. Qt cross-compilation is successful, and a new Raspberry Pi image is burned.
First, insert the TF card of
. /.. /linux/arch/arm/boot/zimage
You can see a file called: Kernel.img under the current folder, which is the new kernel we need.
d, extract modules
The previous step actually not only compiled the kernel source code, some module files are also compiled, here we extract
$CD RASPBERRYPI_SRC
$mkdir Modules
$CD Linux
$ make Modules_install install_mod_path=. /modules
We can get the module files we need in modules
2, upgrade the RPI kernel, Firmware, Lib
Unplug the SD card and plug it into the co
Raspberry Pi, so I created a mount point on both Raspberry Pi and mounted the volume with the following command:

After downloading, through a software "Win32diskimager", to burn the system, in the device Select Reader display external device, image file Select just download, and extract the completed image files, and then click on Write, write operation, Because I am the smallest mirror system, so it takes only a few minutes to complete the system burning, you wait a moment, it is finished.??

Raspberry Pi System image burned to MICRO-SD cardPosted on December 14, 2015
Preparatory work:
1. A 2G or more SD card, preferably a high-speed card, recommended CLASS4 more than the card, because the card speed directly affect the speed of the Raspberry Pi.
2. Download the
Jessie SD card into the computer via the card reader, and note that the Ubuntu system of the virtual machine is selected and Ubuntu will automatically read (mount) the SD cardRootfs (root file system) partition:Firmware (boot partition under Debian Jessie):For files such as boot partition config.txt bootcode.bin cmdline.txt start.elf kernel7.img, refer to the previous Raspberry
Install OpenELEC on Raspberry Pi 2
The next Raspberry Pi 2 has finally arrived, with its small size and ultra-low power consumption. In combination with OpenELEC, it has become a good choice for domestic HD players and simple NAS. This article will briefly describe the tossing experience.Install OpenELEC

A while ago to start a Raspberry Pi, the price of 200多 points, but with the purchase of Chargers, wireless card, memory card and so on, counted less said also has 300;Buy Raspberry Pi 2 B, the configuration is better than before.Because it is a novice, so at first did not buy the whole thing (did not buy memory card),

Recently turned up the Raspberry Pi I bought before, and decided to pick up the Raspberry Pi combined with the go language that I was learning to engage in things. Here first build the environment to run the GO program.

The Internet of Things (IoT) and Bitcoin (Bitcoin) are all fun new things today, so what's the point of putting them together? In short, it is the use of Bitcoin networks for secure, autonomous trading of transactions involving computing resources, storage resources, bandwidth, data, and even public displays that can help other devices display content. The middle will involve sensors, IoT short-range communication protocols, cryptographic currencies and block chains, MapReduce and Hadoop, machin
