for system timing. We can use RTC to specify the boot time, just like an alarm. However, because this feature is rarely used, some boards that provide this feature (such as Intel's original motherboard) cannot be started at the specified time, therefore, it is recommended that you perform the test before using it.The procedure is as follows:1. After the computer is started, press the "Del" key based on the on-screen prompt to go To the BIOS setting s

not measured, find a power supply to change it. 3. If there are no problems with the motherboard, the failure of the motherboard will be more likely. First, check whether the connection between the motherboard and the boot button is loose and whether the switch is normal. You can use a wire to disconnect the switch. If not, try replacing a motherboard. (Note: Try to find boards of the same model or same chipset, because other

structures.For Commonly Used 4-layer panels, there are several cascade methods (from top layer to bottom layer ).(1) siganl_1 (top), Gnd (inner_1), power (inner_2), siganl_2 (bottom ).(2) siganl_1 (top), power (inner_1), Gnd (inner_2), siganl_2 (bottom ).(3) power (top), siganl_1 (inner_1), Gnd (inner_2), siganl_2 (bottom ).Obviously, the power supply layer and formation in solution 3 are not effectively coupled and should not be used.So how should solution 1 and solution 2 be selected? General

has poor contact. In addition, when the system is running, you can use a hand touch or a shell close to the CPU, display, hard disk, and other devices to determine whether the device is running normally based on the temperature. You can use a hand to touch the surface of some chips, if it is hot, the chip is damaged. 3. Plugging Detection As mentioned above, there are many causes of computer faults, including motherboard faults, I/O bus faults, and various plug-in card faults. Plugging and main

I believe that everyone who wants to engage in embedded development will have a dream of becoming a master in this field, a master in Linux driver development, or a high level of kernel development. I always believe that as long as there is a dream in my heart and hard work and sweat, everyone can reach what they want. However, this road is very tortuous and rugged. If you don't have a good leader, you will find yourself crawling in this field for a long time, but it has little effect, and confi

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 LoadingProgram. Includes the firmware (firmware) bootCode(Optional), and bootloader. 2. Linux kernel. Customized kernel and kernel startup parameters specific to embedded boards. 3. file system. Including the ro

the internet of things and standards has largely emerged in the open source community. We will introduce some of the more interesting open source networking projects that are currently being actively developed. Although our list of open source projects is usually focused on software, it also introduces a large number of open source hardware, and amateurs can buy many of them at low prices. As always, if you think other items should be on the list, you are welcome to exchange messages. developme

The EATX motherboard is an abbreviation for the extended ATX, primarily for rackmount server systems. It is typically used on servers that are not capable on dual processors and standard ATX motherboards, with 12x13 inches (305mmx330 mm) in size. Eatx the upper part of the motherboard has the same fixed screw position as ATX and is used for high-performance workstations or servers, EATX is generally very rare in the market because it is designed for workstations specifically. ETX motherboard siz

Summary: What the hell is uboot?(1) The main function of Uboot is to start the operating system kernel.(2) Uboot is also respon

I used the guide to open the Yocto project on the Intel Edison Board to install and configure the board. First we need to connect the Edison through the serial port, and configure the sshd and Wi-Fi, we can use SSH to connect to the Edison after the completion. Because Linux's com

It provides at least a textual relationship for the underlying meaning of the associated term, which is a good beginning for rich XML schemata. From concept to expression In the development process, it is best to capture concepts early. During the analysis of new applications or integration of existing applications, you should document the main concepts and retain as many original concepts as possible. The Turtle syn

advantage of this design concept is that it can help users Reduce network costs from the ports of each module. The disadvantage is that the port efficiency of network data is relatively low, all data exchanges depend on the data processing board capability of the core board. As the number of boards increases, the performance of the entire switch decreases, that is, the number of ports in the chassis is inversely proportional to the performance. In ad
