Boot script files

All QNX BSPs ship with a buildfile, which is a type of control file that provides instructions to the mkifs command-line utility to generate an OS image. The buildfile specifies the particular startup program, environment variables, drivers, etc. to use for creating the image. The boot script portion of a buildfile contains the sequence of commands that the Process Manager executes when your completed image starts up on the target.

Note: For details about the components and grammar of buildfiles, see the section "Configuring an OS image" in the chapter Making an OS Image in Building Embedded Systems, as well as the entry for mkifs in the Utilities Reference.

The QNX System Builder perspective stores the boot script for your project in a .bsh file. If you double-click a .bsh file in the System Builder Projects view, you'll see its contents in the editor.
