Abstract

The invention relates to a debugging port multiplexing method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a pre-configured initial control signal and an input control signal; before an application program is loaded, a debugging port is configured to be in an input non-enabled state and an output non-enabled state according to the initial control signal; after the application program is loaded and before debugging, the debugging port is configured to be in an input enabling state and an output disenabling state according to the initial control signal and the input control signal; and after the application program is debugged, performing multiplexing configuration on the debugging port. By adopting the method, the debugging port not only can resist strong electric pulse, but also can realize an input function during debugging, and the problem of application program reuse can be solved.

Description

technical field [0001] The present application relates to the technical field of debug ports, and in particular, to a debug port multiplexing method, device, computer equipment, storage medium and computer program product. Background technique [0002] The debug port is generally implemented by a PAD (chip pin) with input enable and output enable. In the traditional debug port multiplexing method, the PAD needs to be configured as an input state before the application program runs. The PAD can realize the input function during debugging and can realize multiplexing. However, the PAD configured in the input state is very vulnerable to the attack of external strong electric pulses and damages the internal circuit. Therefore, it is particularly important to solve the problem of anti-strong electric pulse of the debug port on the basis of the traditional debug port multiplexing method. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a debug port m...
