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...
