Building a flash filesystem image

If your application requires a writable filesystem and you have flash memory devices in your embedded system, then you can use a QNX Neutrino flash filesystem driver to provide a POSIX-compatible filesystem. The flash filesystem drivers are described in the Filesystems chapter of the System Architecture guide. The chapter on customizing the flash filesystem in this book describes how you can build a flash filesystem driver for your embedded system.

You have two options when creating a flash filesystem:

In this section we describe how to create a flash filesystem image file using the mkefs (for make embedded filesystem) utility and a buildfile. How to transfer the flash filesystem image onto your target system is described in the "Embedding an image" section. For details on how to use the flash filesystem drivers, see the Utilities Reference.
