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.

to use, provided that you can get more than one address. It is not suitable for anyone who wants to conduct various network experiments, because you cannot control the network of the virtual machine and it goes out directly. The schematic diagram is as follows:

Because the ARM architecture Development Board can be based on the X86 architecture of the PC on the CPU instruction and the binary is different, and if the Linux driver needs to access the hardware, these hardware is difficult to simulate on the PC, so we need to debug and test on the Development Board with these hard
Configuration of tftp server in ubuntu 10.04 and use of tftp commands on the Development Board tftp server in ubuntu 10.04: Step 4: install the software required for tftp. First, install tftp-hpa and tftpd-hpa. The former is the client and the latter is the service program. Enter sudo apt-get install tftp-hpa tftpd-hpa on the terminal, install tftp-hpa and tftpd-hpa. Then you need to install xinetd, enter s

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
Porting linux2.6.24 to the FS2410 Development Board is a preliminary success-Linux general technology-Linux programming and kernel information. The following is a detailed description. It is not accurate because the Linux kernel 2.6.24 has included the s3c2410 kernel. During the transplantation, you only need to make a few minor changes and pay attention to them.

After two days, it almost crashes. Finally.
The Development Board is directly connected to the PC network cable (note that it is not a common network cable, but a specific network cable ).
