It has been almost a month since I started this development board, but it is still not very practical to follow the tutorial video to learn the test code step by step and install all kinds of tools and software. Many commands are still entered like a gourd and observe the input results, always feel floating on the surface. If you want to dig deeper, the tutorial will immediately give you a reminder: to change your mind, you only need to know most of it, and you will have some experience when you are familiar with it. So I learned the introduction to Linux system programming.

First a brief description of the development board, bought on a treasure. The chip is Samsung's latest Exynos4412 (Orion), based on ARM Cortex A9 architecture, with a main frequency of 1.4G. The core board uses the SCP style, with four 256m memory on the periphery, with a total of 1G MMC8G. In the aspect of display, a 4.3 "resistive screen is selected (cheap entry model, poor touch and incorrect color, make do with a mouse). Other configurations are a little. The upper end runs unbantu with a virtual machine, and you can hang linux or android below.

The reason why we chose Xunwei rather than Wei Dongshan mainly lies in the chip model, which is still using 2440 to eliminate the goods, and the course fees are a little bit unenterprising. As a technician, what I despise most is this kind of manufacturer, who makes use of information asymmetry to peddle some outdated goods to mislead people.

The Unbantu version uses 12.0.4core Android version to start learning with 4.0.3 using a factory-configured compilation environment. Because the compilation environment is time-consuming and laborious to build, it is not easy to install a MDK. The virtual machine version uses the VMware10.0.1,Win7 system. Then there is a bunch of tools: SSH,VIM,SourceInsight,HyperTerminal,NotePad++,Fastboot,Android ADB. The procedure is more tedious, but it is not difficult. According to the tutorial step by step, each little guy touches his head and his face is familiar. (end)
