You can create bootable image filesystems, flash filesystems, or a combination of the two.
The
IDE helps you create the following image types:
- OS image (.ifs file)
- An image filesystem. A bootable image filesystem holds the
procnto module, your boot script, and possibly other components
such as drivers and shared objects.
- Flash image (.efs file)
- A flash filesystem. (The “e” stands for embedded.) You can use your flash
memory like a hard disk to store programs and data.
- Combined image
- An image created by joining together multiple components (IPL, OS image,
embedded filesystem image) into a single image. You might want to combine an IPL
with an OS image, for example, and then download that single image to the
board's memory via a ROM monitor, which you could use to burn the image into
flash. The filename extension of a combined image indicates the file's format:
.elf, .srec, etc.
If you plan to debug applications on the target, you must include pdebug
in /usr/bin. If the target has no other forms of storage, include
pdebug in the OS image or flash image.
