Abstract

The invention discloses an upgrade method and system of a single chip microcomputer. The method comprises the steps of receiving a software upgrade package through the single chip microcomputer software MCU FW download board connected with a software protector Dongle; upgrading the single chip microcomputer in the Dongle according to the software upgrade package. By adopting the technical scheme, the upgrade of the single chip microcomputer in the Dongle is simple and easy to achieve, and the technical problems that the upgrade method of the single chip microcomputer in the software protector in the prior art is strenuous and the appearance of the software protector is damaged are solved.

Description

technical field [0001] The invention relates to the field of single-chip microcomputers, in particular to a single-chip microcomputer upgrading method and system. Background technique [0002] In the related art, in many applications of the dongle, a single chip microcomputer (MicroControl Unit, MCU for short) needs to be used to control the main chip. After the mass production of the dongle, the software of the single-chip microcomputer may be upgraded for some compatibility problems encountered. On the finished product of the dongle, an upgrade interface is specially reserved for the single-chip microcomputer, which is not beautiful and increases the cost; and opening the shell of the dongle to upgrade is laborious and may damage the appearance of the dongle. For this reason, for the video graphics array dongle VGA dongle with charging function, we propose a simple way to upgrade the software of single-chip microcomputer. [0003] In the related art, there is no effectiv...
