Embodiment 1

[0022] figure 1 The implementation flow of the hardware debugging method provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0023] In step S101, when the system is turned on, the hardware performance in the non-volatile random access memory NVRAM is restored to a preset default value, and the default value is read to initialize the control register.

[0024] In this embodiment, the system includes but is not limited to a system of a tablet computer, a notebook computer, a desktop computer, and a server.

[0025] The hardware performance includes but not limited to CPU frequency, input / output frequency, number of CPU cores, and MCU frequency.

[0026] Said restoring the hardware performance in the non-volatile random access memory NVRAM to the preset default value means that when the pin output of the bus expander GPIO corresponding to the hardware performance is judged to be a high level, the non-volatile random access The hardware ...

Embodiment 2

[0055] image 3 The composition structure of the hardware debugging device provided by Embodiment 2 of the present invention is shown. This device is mainly used in the Feiteng platform, and is suitable for tablet computers, notebook computers, desktop computers and servers, and is used to run the present invention figure 1 and figure 2 The hardware debugging method described in the embodiment. For ease of description, only the parts related to this embodiment are shown.

[0056] refer to image 3 , the device consists of:

[0057] The initialization unit 31 restores the hardware performance in the non-volatile random access memory NVRAM to a preset default value when the system is turned on, and reads the default value to initialize the control register.

[0058] Further, the initialization unit 31 is specifically used for:

[0059] Start the system, and judge whether the output level of the GPIO pin of the bus expander corresponding to the hardware performance is high...

Abstract

The present invention is applicable to the computer field, and provides a hardware debugging method. The method includes the following steps: when the system is turned on, the hardware performance in the non-volatile random access memory NVRAM is restored to a preset default value, and the read The default value is to initialize the control register; after initialization, enter the user management interface, receive the hardware performance debugging value set by the user through the user management interface, and store the debugging value into NVRAM; read the debugging value in NVRAM for debugging. The invention can simplify the operation of hardware debugging and solve the problem of starting the system when the user inputs the debugging value not supported by the hardware through the user management interface.

Description

technical field [0001] The invention belongs to the field of computers, in particular to a hardware debugging method and device. Background technique [0002] In the prior art, the debugging of computer hardware is cumbersome and time-consuming. For example, when debugging the frequency and timing of the CPU and MCU, it is mainly to input the specific debugging value into the corresponding control register through the serial port debugging line. This method requires another machine to be used as a debugging machine to input the debugging value; when the input data is wrong, the machine needs to be restarted; and the waiting time for starting up is long, and it is difficult to operate when performing large-scale verification. [0003] At present, there is also a method of debugging CPU and MCU through the user management interface. This method can solve the above problems, but when the user management interface inputs a debugging value that is not supported by the hardware, ...
