Abstract

The invention discloses a software online upgrading method based on a F2812 chip. The method comprises the following steps: 1, storing a resident software and an initial work software in a FLASH spaceof the F2812 chip; step 2, electrifying, starting the resident software, and judging whether the electrifying time is in a time window, wherein, if the electrifying time is in the time window, the resident software receives an upgrading instruction, the resident software further receives a new work software, erases the initial work software and writes in the new work software, and the new work software starts working, and if the electrifying time is not in the time window, the resident software verifies an area where the initial work software is stored. With the method provided by the invention, working efficiency is improved, and operating maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the field of operation and maintenance of embedded systems, and in particular relates to an online software upgrading method based on an F2812 chip. Background technique [0002] Embedded systems have been widely used in various control, measurement and other equipment manufacturing fields. Compared with hardware circuits, embedded software has the advantages of convenient modification, no storage period, and no new components or reliability changes will be introduced in the modification. [0003] What follows is that software upgrades have become an important daily work in product development and post-maintenance. Currently, embedded devices targeting the F2812 hardware platform generally need to be upgraded through the JTAG interface on the circuit board. It is necessary to open the sealed structure of the device first, and then physically connect the emulator to the circuit board. After the upgrade is completed, reassemble...
