This article introduces in detail the concept of boot loader, which is based on the OS boot loader in the embedded system, The main tasks of software design and the structure framework. 1. Introduction Running GNU/Linux systems on dedicated embedded boards has become increasingly popular. An embedded Linux system can be divided into four levels from the software perspective: 1. boot the loader. Includes the Boot Code (optional) in the firmware and t

Question: 1372-Log Jumping the start position and length of n boards. Overlapping boards can jump to each other to obtain the maximum number of rings. Train of Thought: first sort by the starting position, and then judge whether he and the previous one can jump to each other with one more board each time. If yes, they can add more boards. Code: # Include #

would be a bit difficult if it was born from hardware.Q: Is the minimum system board good at Layer 2 or Layer 4?Answer: Only at91 can use two-layer boards, and the other can have at least four layers. The ground and power supply of 44b0 can also be well processed by Two-layer boards;Four-layer plates and 33 euro resistance:The selection of four layers is not only a problem of power supply and ground, the h

Socket 478 Intel recently plans to enable all Pentium 4 series processors to adopt the new socket478 package. This is due to the 0.13 micron process, and the Pentium 4 processor based on the Northwood core must use the socket478 package. By the fourth quarter of this year, the frequency of the series of processors will exceed 2 GHz. Under pressure from motherboard manufacturers, Intel is preparing to increase the output of the Willamette core socket478 processor. The reason is that the Northwo

How to get started with the Development BoardMf development boards are both stm32 Single-Chip Microcomputer Development Boards. Generally,

The background is probably the story of a capitalist exploiting the residual value of a worker .... There is a piece of wood, cut it into several lengths, the cost of one cut is the length of the whole piece of wood cut, for example, if you want to cut a piece of wood with a length of 21 into 2 and 19 at a cost of 21, you can set the length and sequence of the two pieces by yourself. Idea: an obvious greedy idea is to cut down the longest board each time, so that the longest Board will not be us

role of cmos ram is to save the hardware configurations of the system and set certain parameters for users.Because the power consumption of cmos ram is extremely low, the backup battery on the cmos ram * motherboard can be powered off after the system power is off. Therefore, the user setting parameters stored in the CMOS will not be lost. Cmos ram is only a storage chip and only supports data storage. Special Programs are required for parameter settings in CMOS. The CMOS setup program of early

machine will easily crash during running. You can use special tools and software for troubleshooting. If the damage is serious, you can only replace the hard disk. In addition, for boards that do not support udma 66/100, you should pay attention to the setting of the hard disk running mode in CMOS. 2. software-related crashes [Improper software upgrade]Most people may think that the software upgrade will not be a problem. In fact, some components sha

Page 1st: one-stop teaching of General forum intrusion (figure) At present, there is a new trend on the Internet. The Hacker's attack targets have extended from the website to public places such as forums, chat rooms, and message boards, the Forum passwords of many users are exactly the same as those of e-mail and QQ, which poses a great threat to network security. In other words, hackers can gain higher permissions by intr

I used a simplified method here, but it was code simplification or the sub-governance recursion idea. One is divided into 4, until 2*2 can be solved directly. The placement of the four dominoes exactly corresponds to: dir [4] [2] = {0, 0}, {0, 1}, {1, 1}, {1, 0 }}; these four directions. The four directions can be used to determine the four directions of the incomplete position (top left, top right, bottom right, and bottom left ). Therefore, we can use a loop instead of judging the four directi

to create a sequence in a sequence adapter: Square sequence embedding. The adapter mode shows how to combine these two types. In the decorator mode, we want to add some out-of-the-box functions during the attack, such as digging holes and rolling boards on the hosts, so we don't have to worry about how to use the two irrelevant ones. We should first create an interface: Public interface work{Public void insert ();}　 Interface work has

Recently, some FPGA boards (ep4ce30f23c8n) were maintained, and we found that there were a pair of ground-to-ground short circuits for both 3.3v and 1.2v FPGA boards. After removing some chips powered by 3.3v, they were still short-circuited, there is no way to simply remove the FPGA chip. As a result, the short-circuit phenomenon disappears. It turns out that the FPGA 3.3v and 1.2v are short-circuited; F

When we conduct PCB cabling, we always face two or three kinds of situations on one board. The silly practice is of course, regardless of the case of November 21, copper is applied as long as it is the ground. This is not a problem for low-speed boards or boards that are insensitive to interference. Otherwise, the Boards may not work properly. Of course, if there

Let the Windows operating system achieve automated operations (group chart)-General Linux technology-Linux technology and application information, the following is a detailed description. Do you want to make your computer smarter and more humane? Do you want your computer to automatically do something for you? Next I will introduce the computer's "Automation ". It makes computers smarter and easier for you to work and learn. Automatic boot Automatic boot is a very practical function. We ca

surrounded by two USB ports and a network port, can connect keyboard, mouse and network cable, with video analog signal of the TV output interface and HDMI HD video Output interface, All of the above components are integrated on a motherboard that is only slightly larger than the credit card, with all the basic functions of the PC just by turning on the TV and keyboard, you can perform many functions such as spreadsheets, word processing, playing games, and playing high-definition video.

What console is used is determined by the hardware board. The PX4 boards (such as PX4V1 and Pixhawk) are USB connectors.For example, if you have a mavproxy agent insta

A single Board running processing business (motherboard), another single board idling (backup board), waiting for the processing board when the problem itself on top. The motherboard synchronizes the processed business data to the backup board in real time. It can be said that the backup board is the main clone. Forwarding system Once a problem has been found on the motherboard, directly switch the message link to the ba
