Abstract

The invention discloses a chip debugging method and device based on a serial port.The method comprises the steps that when a chip debugging signal is received, the serial port is switched to be in a communication interface mode, wherein the chip debugging signal is used for requesting to debug a chip to be debugged; a debugging program needed by the chip to be debugged is obtained according to the chip debugging signal; the debugging program is sent down to the chip to be debugged through the serial port, wherein the chip to be debugged is debugged by means of the debugging program.By means of the chip debugging method and device based on the serial port, the technical problem that in related technologies, due to the fact that a specialized programmer needs to be used for conducting program recording on the chip, the chip debugging cost is increased is solved.

Description

technical field [0001] The invention relates to the field of chips, in particular to a chip debugging method and device based on a serial port. Background technique [0002] With the rapid development of electronic technology, the application of electronic chips is becoming more and more extensive. In order to meet the requirement that the chip can realize different functions, it is necessary to burn the corresponding function program on the chip. When programming and upgrading the chip, the prior art usually uses a dedicated programmer. However, the use of a dedicated burner to program the chip and program upgrades has the following disadvantages: the software tools and hardware tools required for burning are dedicated, which not only limits the chip model, but also increases the cost; The need to switch the use of the serial port has caused great inconvenience to the chip programming process. [0003] Aiming at the problem that related technologies require a dedicated p...
