Problems solved by technology

In the traditional development process, no matter what the demand mode is, the target machine only supports a fixed communication method, and a fixed communication method is not suitable for the software update and debugging requirements of the target machine in different development stages of the system. This target machine communication The singleness of the mode leads to complex software update and debugging process in the system development stage, low efficiency and increased system development cost

Embodiment Construction

[0012] The following takes the target computer's software maintenance in single-board or system mode as an example to introduce a multi-mode compatible target computer software maintenance method. The overall flow chart of the method is shown in figure 1 ,Specific steps are as follows:

[0013] Step one: On the target machine, formulate a unified calling interface for various maintenance service requirements such as software update and debugging on the target machine, such as developing a unified service calling interface for the target machine's Flash access, register reading, and memory access, and the same type of service The calling service interface when accessed through different communication interfaces of the target machine is exactly the same.

[0014] Step 2 The target machine is in single board mode according to the maintenance requirements. It is maintained in single board mode or in system mode. Based on the overall system maintenance, after the target machine starts a...

Abstract

The invention belongs to the embedded software development and design technology, and particularly relates to a target machine software maintenance communication method compatible with multiple modes. The target machine software maintenance communication method compatible with multiple modes includes the steps that a unified calling interface for maintenance services such as software updating and debugging is made in a target machine; the target machine cyclically queries whether data is received among communication interfaces which the target machine supports under the target machine software maintenance state; after data is received from any interface, data continues to be received from the interface till a complete pack of data is formed; then, service information, called by an upper computer, in the data pack is analyzed based on the communication protocol under the interface, and a corresponding maintenance service in the target machine is called; after response data of the maintenance service is obtained, the response data is returned through the communication interface, and one maintenance service request of the upper computer is met; then, the target machine continues to cyclically query among the communication interfaces, the process is repeated, and maintenance service support for the interfaces is achieved.

Description

Technical field [0001] The invention belongs to embedded software development and design technology, and specifically relates to a compatible multi-mode target computer software maintenance communication method. Background technique [0002] For embedded systems composed of multiple target computers with different architectures, in different development stages of the system, each target computer has different software update and debugging connection requirements, and there are different communication methods between the host and the target computer under each requirement. , Such as communication via serial port or Ethernet cable in the single-board development stage, communication via internal bus in the system maintenance stage, etc. In the traditional development process, the target machine only supports a fixed communication method under any demand mode, and a fixed communication is not suitable for the system's software update and debugging requirements in different developme...
