Embodiment Construction

[0022] Relevant detailed description and technical contents of the present invention are as follows now in conjunction with the accompanying drawings:

[0023] see first figure 2 , figure 2 It is a schematic diagram of the software system (device side) of the debugging method of the present invention. The software system of the present invention mainly includes a hardware debugging driver (can exist independently or be written together with the real driver of the hardware), and the hardware debugging driver realizes the simplest driver interface, accesses memory and registers through memory images, and monitors Hardware interrupts, generating Log files that record on-site information; a control program that parses scripts and manual commands, controls the hardware debugging driver to read and write memory and registers, and is responsible for interacting with remote programs and forwarding status information in the remote debugging state. The interface connecting the hardw...

Abstract

Disclosed is a debugging method for embedded devices which comprises steps of: a. providing a hardware driver and accessing memory and registers via storage image; b. providing a control program to control hardware debugging driver read / write memory and register independently; c. connects the hardware debugging driver and the control program with standard application interface.

Description

technical field [0001] The invention relates to the field of computers, in particular to an embedded device debugging method and a debugging tool thereof. Background technique [0002] At present, the main debugging method applied to embedded devices such as PDA (Personal Digital Assistant, personal digital assistant) is to directly observe the debugging information or remotely monitor some system operation status. The software system of this existing embedded device debugging method such as figure 1 As shown, several drivers and class drivers at the bottom are responsible for driving their respective devices. These drivers are uniformly controlled by the operating system kernel. The operating system kernel is connected to the application program through the standard application library, thus forming a driver-based , the application program is the complete software system at the highest level. The application program receives instructions through its man-machine interface ...
