The previous chapters mainly describe the installation and construction of the native Linux Android development environment and the porting of the Android system. This chapter focuses on how to install Android on the Development Board . Development boards are the main hardware devices for developing and learning embed

Boa is a very small Web server with only about 60 kb of code to be executed. As a single-task web server, BOA can only complete user requests in sequence, rather than fork new processes to process concurrent connection requests. However, BOA supports CGI and can execute a process for the CGI program fork. Boa is designed to speed and security.
The following describes how to port A Boa Server.

Learn Linux drivers, then how to download data to the Development Board. My main use is two kinds:1.MountIt is convenient to mount the board to an NFS file on the Ubuntu host (provided that Ubuntu installs the NFS service), as I mount the/work/nfs_root directory to Ubuntu, as in the following command Mount-t Nfs-o nolock 192.168.1.20:/work/nfs_root/mntSo in the
1. OverviewEmbedded system consists of hardware environment, embedded operating system and application, hardware environment is the hardware platform of operating system and application, it has different requirements depending on the application. The diversity of hardware platform is the main feature of embedded system, how to make the embedded operating system run effectively on different hardware platform is the key problem in the development of emb
This note notes about putting tq2440 's factory uboot (U-boot-1.1.6_q43_20141118.bin) through the Jtag V8 burning to Norflash.Starting Uboot from Norflash, you can either test the bare-metal program, or you can use the Norflash uboot to burn the uboot image to NAND flash via USB and boot the Linux kernel in NAND flash.
Installing Jtag burning Software (jlinkarm_v402d)

actually an interesting and enlightening discipline that teaches us to think and solve problems. With a micro-computer like Turnipbit, we don't need to write code on a computer, learn programming in a boring way, but can easily create our own games, music, scientific experiments, and control robots with graphical drag-and-drop programming.Turnipbit is mainly aimed at teenagers, small white, geeks learning programming technology, so the corresponding develop
″tftp_directory= "TFTP root" #服务器目录, such as/home/tang/wkdir/tftp, need to set permissions to 777,CHOMD 777Tftp_options= "-l–c–s"3. Restart the TFTP servicesudo service tftpd-hpa restartThen you need to download u-boot (bootloader), which can only be downloaded via Jtag Jlink.
Virtual machines and Windows network configuration
It is recommended to use fewer virtual machines, because there are always problems like this, and now I have developed directly under the native Linux operat

But if the network can not use, only through the serial port to download what to do? This time there are two tools to
This document describes the lab steps for invoking shell commands in a Linux system environment, and the document compression package LINUX-CFrom the "itop-Development Board-minilinux-shell_v1.0.zip" is the C program source code.The shell of the Linux system is the shell of the operating system, providing the user with an interface to use the operating system. It's the command language.and programming langu
The Development Board launched earlier does not have a network port. Therefore, many network-based functions of the. NET micro framework cannot be studied. In the IOT era, network functions are king.
In addition to the Ethernet module, the New Development Board also adds the USB Host module and other related interfaces
AC6102 Development Board USB3.0 test and use instructionsOverviewThe AC6102 incorporates a cypress-launched high-performance USB3.0 transmission chip cyusb3014,cypress called EZ-USBFX3. The chip features strong, powerful, simple interface and is ideal for use in a variety of applications where high-speed data transmission is required, following an introduction to the chip from the EZ-USBFX3 data sheet:Cypre

This article explains how to debug our applications with the NFS network file system, where we use the Linux qt system asCases.When we debug the application on the qt system, we first build the executable binaries on the virtual machine Ubuntu by cross-compiling,Then copy the generated binaries to the file system, then regenerate the system.imgwith the command, then burn the system.img toDevelopment Board, and then launch the
Today, we got a Development Board, bv561evb, from Hefei Youshi technology. It consists of a basic board and a power board. It is very small and exquisite, and it looks like 10 cm x 7cm. Connect the 12 V power cord, connect to the serial port, open the Super Terminal, configure it to 115200-n-1, then connect the network
