This article is about how Utility can be dynamically updated. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Since VxWorks is an embedded operating system, the word "embedded" means "App should be embedded in OS and OS should be embedded in Hardware". It is a trinity.

one

As a result, on devices running VxWorks, App is often compiled with the VxWorks system image. Then the upgrade of the software system is the update of the image of the whole system. The system image is just a file called "VxWorks". Then the next question is how to update the file. Therefore, it is OK to use the file transfer protocol directly.

two

What if App and OS are separate? VxWorks6 specially designed an independent App scheme: RTP. If you use RTP, App is a user-mode program, which is stored separately and is very easy to update dynamically. And VxWorks provides several ways to load RTP programs

three

More people are used to putting App in the kernel state and using separate DKM projects to create .o or .out files. So how do you update this App dynamically?

We know that there is a command in Shell: ld ()

Use it to dynamically load App
