Abstract

The invention discloses a hardware control device and method for MCU chip testing, a storage medium and equipment, and belongs to the technical field of hard test pieces. The method mainly comprises the steps that a test control end is connected with a port multiplexing hardware module, the test control end is connected with the port multiplexing hardware module and sends a corresponding test operation instruction according to a function needing to be tested so as to control opening and closing of a corresponding communication interface in the port multiplexing hardware module, and the port multiplexing hardware module is connected with a tested MCU chip and sends a corresponding test operation instruction according to the function needing to be tested so as to control opening and closing of the corresponding communication interface in the port multiplexing hardware module. And carrying out corresponding function test on the tested MCU chip through the communication interface. By adopting the multiplexing principle and utilizing the port multiplexing hardware module to connect the tested chip, any communication port of the tested chip can be effectively accessed through the port multiplexing hardware module, no conflict is generated, the full test requirement can be completely met, the scheme has higher flexibility, and the test efficiency is improved. And the full-function test of the hardware can be realized without repeated manual wiring.

Description

technical field [0001] The present application relates to the technical field of hardware testing, in particular to a hardware control device, method, storage medium and equipment for MCU chip testing. Background technique [0002] In the hardware test environment of MCU chips, there are usually pin compatibility problems between different chips, so that the hardware test platform of the previous type of chip cannot be used directly for another type of chip, and the hardware platform needs to be reconfigured. design. Even for the same chip, it is not easy to achieve full coverage of functional tests on the hardware platform. Generally, there are various external interfaces in MCU chips, such as I2C, I2S, UART, SPI, etc. These interfaces are incompatible with each other and each has its own communication protocol. These communication protocols are generally encoded and decoded by hardware, and software is responsible for sending, receiving and processing data. When testing...
