Some of these layers are used by the system itself, such as the visible grid (visible mesh layer) for the designer to easily locate when drawing. While the keep Put (prohibit wiring layer) is used in automatic wiring, manual wiring does not need to use. for hand-drawn double-sided printed circuit boards, the most used is the top Layers (top layer copper cabling), Bottom L

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

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

It defines the operating status of the circuit board or the position in the system, if the hardware note is set incorrectly, the circuit board may not work properly. 3) The circuit plate type is not suitable.After the hardware is updated, the circuit board with the same name may have multiple models. In general, the functions of the new model board are compatible with those of the old model board, but the functions of the old model board are not necessarily compatible with

You may suspect that the fault is caused. Adjust the two user boards. If the fault occurs with the Board, the corresponding port on the user board is damaged, and the switch user board is back to normal on the backend day. 3) User Board base or backboard faultAfter judging whet

The bucket that holds water is made up of many wooden boards, and the amount of water is determined by these boards. If one of the wooden boards is short, the amount of water in the barrel is limited by the short board. This short board has become a "limiting factor" (or "short board effect") for this bucket to hold water "). To increase the volume of water in th

The experiment environment needs to be changed to the Linux 2.6 kernel, but the Linux kernel installed on the arm2410s Development Board in the lab is 2.4, so you have to re-burn all the development boards to the kernel! As the kernel image and root file system change, you need to modify the flash partition, that is, modify the VIVI source code smdk. in the c file, mtd_partition_t default_mtd_partitions [], re-compile Vivi, and then burn Vivi to the D
