Problems solved by technology

At present, in order to meet the needs of interchangeability, all software needs to be programmed in the general processing module, which not only takes up a lot of space, but also increases the cost of ground loading and curing
[0006] 2) The requirement of redundant backup brings the problem of complex software deployment methods
The problem is that the curing time is longer and the scalability is poor

Embodiment Construction

[0050] In this embodiment, the large-capacity storage module is selected as the data server to provide data loading services for the entire system, and the data is transmitted through the FC interface on the module. The module is also equipped with a large-capacity storage medium (SSD) for Save all the loading data required in the remote data loading system, the software running framework is as follows Figure 4 shown.

[0051] In this example, the data processing module is selected as the target machine, which resides in the VxWorks653 operating system, and can remotely obtain and load data from the large-capacity storage module; the switching interconnection between the large-capacity storage module and the data processing module based on FC realizes High-speed data communication between modules.

[0052] Use the following method to configure NFS over FC in the data processing module:

[0053] (1) Install NFS driver

[0054] Use nfsDrvInstall() to install the NFS driver. ...

Abstract

The present invention relates to a kind of remote starting method based on VxWorks653 and NFS over FC, it is characterized in that, concrete steps are as follows: (1) after Vxworks 653 is started, create bootCmdLoop task, and call bootLoad function; (2) carry out equipment initialization; (3) ) Register iosDrvInstall to the IO layer; (4) add the NFS system to the system IO; (5) use the open and read functions to load the image file from the NFS system through standard system calls; (6) start the VxWorks653 system image. The invention defines the transmission protocol of NFS over FC, and replaces the local file reading interface with the interface provided by the network file system, thereby simplifying the design of Boot startup in the VxWorks653 system.

Description

technical field [0001] The invention relates to a remote start method based on VxWorks653 and NFS over FC in the embedded field of avionics. Background technique [0002] With the development of avionics technology, more and more projects adopt the Integrated Modular Avionics Architecture (IMA). The IMA architecture realizes the integration and sharing of avionics resources, making most applications reside on general-purpose processing modules. , forming the core computing function. While the IMA architecture brings resource integration and sharing, it also brings problems of high system coupling and complex software deployment. [0003] In the joint architecture, the software is bound to the hardware, and only the software related to the hardware resides in the hardware, but in the IMA architecture, the software and the hardware are separated, and the software can reside in any module of the general processing module. Modules have the characteristics of interchangeability...
