Method for synchronously programming Linux firmware and applications in multiple devices

Abstract

Along with continuous development of embedded industry, the production efficiency of embedded devices is required to be continuously improved. The invention provides a method for synchronously programming Linux firmware and applications in multiple devices. More convenient and quicker production is realized. In a network port startup mode, a virtual machine allocates an IP to a DHCP of a device after the device is powered on, and the device requests for a UBOOT file to a server after obtaining the IP; after UBOOT, a script is obtained from the server and is executed in a memory, and the scriptis used for obtaining UBOOT, KERNEL and ROOTFS files from the TFTP server again and programming the files to a FLASH; after the programming is finished, the device is restarted; and a Linux system runs an app in the system after being started, and a latest application is updated in a host. The method at most can support simultaneous programming of 255 devices without manual operation, and the programming can be finished by only powering on the devices and accessing the devices to network ports; the multi-device synchronous programming method provided by the invention greatly shortens the programming time during production and has a function of automatically updating the applications, and the whole process is free of the manual operation, so that the production efficiency is greatly improved; and therefore, the method has very high useful values.

Description

technical field [0001] The invention relates to the technical field of Linux systems, specifically a fully automatic programming Linux system and its application programs, mainly a method for synchronously programming Linux firmware and application programs with multiple devices. Background technique [0002] With the in-depth development of computer technology, Internet technology and single-chip microcomputer technology, embedded systems have entered a new historical development stage after decades of development, that is, from general low-end applications to high-end and low-end applications. The era of parallel development of the end and the continuous improvement of the level of low-end application technology is marked by the development of 32-bit embedded systems. With the advent of the era of network, communication, multimedia, and information home appliances, embedded systems have been widely used. The frequency of use of various new embedded system devices has grea...

Problems solved by technology

After the traditional embedded device comes back from the device patch, the firmware must be programmed first, and the next step can only be carried out after the programming is completed; while the traditional programming method, various methods of downloading the firmware from the PC to the development board , mainly including JTAG, NFS mount, Nand Flash and Nor Flash, USB, RS232, network card NIC and other methods; and these methods require manual programming of each device, which greatly increases labor costs and reduces production Efficiency, in severe cases, it will also affect the production of enterprises
