What is U-bootThe Bootloader of the hi3518ev200 veneer adopts u-boot.U-boot is a commonly used in embedded systems Bootloader,bootloader is a small program executed before the operating system, through which we can initialize the hardware device, establish the Memory space mapp

Environment:Development Board: Freescale 2.6 armv71, the system is read only , the only path to read and write is/TMP/SD (this is an SD card). The program is placed under/tmp/sd/transfer (instead of the run path below), and the SQL statement is saved as a file on the Development Board, and the statement character set is GBK. Server: The server is installing SQL S

工欲善其事, its prerequisite, as the first article in my Android Kernel development series, let's first address a non-technical issue: Learn Android kernel development, do you need to buy an Android development board? If so, what kind of development boards should you choose?1. Do

In the "can_485_module_v1.x" Hardware data compression package, provide a schematic diagram of the Cadence format andSchematic diagram of PCB, AD format and PDF format.The Linux driver for the 485 module is the "drivers/char/max485_ctl.c" file in the kernel directory, the default kernelThe driver is already included in the image.The test routine provides a "Schindler itop-imx6-minilinux-rs485_v1.x" compression package.1 Hardware ConnectionThe hardware tested in this document is two pieces of ito

This two days wrote an LED driver, online also read a lot of posts. Start thinking very clear, is to see the circuit diagram first, found that LED lights are connected to the GPM port, Then look at the s3c6410 data manual, first to Gpmcon mouth to write command words, let gpm0-5 set to output, and then to the gpmdat mouth write data words, in the gpm0-5 pin pull low or pull high level, Thereby controlling the LED's light and extinguish. 1. Circuit diagram It's obvious that the LED lights are un

SQLite, a lightweight database that adheres to the acid-related database management system, is designed to be embedded and is now used in many embedded productsIt occupies very low resources, in the embedded device, may only need hundreds of K of memory is enough. It can support Windows/linux/unix and so on mainstream operating system, and can be combined with many programming languages, such as TCL, C #, PHP, Java, and ODBC interface, also compared to MySQL, PostgreSQL, the two open source worl

I was in the process of developing thinking about whether I could sign in to the Development Board in Ubuntu, the answer is YES! There's more than one way to sign in, and here's how to log in to the board using Telnet. Just imagine, if you can login to the Development Board

In the fourth chapter, the Android application development environment and the Linux kernel development environment are introduced. Both sets of development environments are prerequisites for Linux development and testing. With two sets of development environments, it's a go

0. Prefaceactually quite busy, but this article summarizes the content I probably got two days, so still want to summarize, feel is relatively trivial, but lest next time again to do part of the work wasted energy. Most of the tutorials on the web probably teach a Windows computer to do a client, a Linux virtual machine, and then connect to the board. I directly to the windows of that machine province, because I am not too accustomed to use Windows to

1. First install the TFTP server in Linux, see the previous article reproduced in the log. It's basically no problem.2. Linux Internet use Bridge, set Windows,linux, the IP of the Development Board is 192.168.1.X1,192.168.1.X2,192.168.1.X3 respectively. This is important! Must be bridged! The original because in school with IPv6 net plus Bras,ip is automatically obtained, so before Linux Internet use is NAT

After many days of QT transplantation, we finally got it out today. Record the learning process, but it makes me sad. Let's talk about the QT source code package. I was very confused when I first installed QT, And I had X11, embedded, and everywhere. Now I understand that X11 can be installed to develop applications running on a PC, and some QT development tools designer and qvfb will be generated. Install embedded to develop QT applications running o
