1. ConceptThe Linux device tree is a file used to describe hardware and some of the boot instructions, passed to the kernel by bootloader,The kernel parses this file and uses different parameters for the hardware.For example, two development boards

Xapp1078 was created in February 2013. This article describes the way to start running two cores, with two CPU cores running Linux and Bare-metal, respectively. It's been the past four years, so call it a traditional amp solution.Key processes for this scenario:(1) Modify the FSBL source code so that it can load multiple elf and bit files until it encounters the flag load address to stop load and return to run U-boot.(2) through the configuration file image.bif core0 u-boot.elf and core1 bare-me

. The system partition command after successful startup is as follows 　　　　　　　　　　　　 1 DF -H 2 fdisk/dev/mmcblk0 14. Enter d (delete), 2 (second partition), n (New), and press Enter four times (with default setting), W (Save and exit) 15. Restart 16.

The second file you ' ll need are a TCL file containing the necessary preset information for the microzed. We'll run this TCL file once we have created a project.After starting Vivado, the first step was to create a new project. My first microzed project would be is an RTL project and would not contain

Application foreground of gesture recognition: intellectualization, familyThe advent of the intelligent machine era has greatly increased the demand for gesture recognition systems. It represents a more natural and direct human-computer interaction, in the smart TV, intelligent machines, and smart home and other aspects have a very broad application prospects. Especially in smart TV, such as TV reading, channel control and so on
