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

Tutorial: Compile u-boot1.1.4 and above to start the development board based on S3C2410 -- Linux general technology-Linux programming and kernel information, the following is the details to read. Someone has tried to compile U-BOOT 1.1.4 or above to start the S3C2410/SMDK2410 compatible development board? I recently tr

[Reprinted] The 4412 Development Board, PC, and ubuntu are connected through a network cable, and the 4412 ubuntu Today, we can see that the Development Board uses TFTP to download programs directly from ubuntu without having to download them through the burning file system all the time. I tried it and the virtual mach

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

Recently debugged the serial port above the bottom of the s5pv210 you made. Because writing a program is cumbersome to test a serial port. So, a direct transplant of a minicom onto the development Board. This allows the serial port to send and receive directly. Especially when I need to test multiple serial ports at the same time, faster than writing programs. No more nonsense, look at the operation flow be

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
