Software and Hardware image in an EPCSx config mem

The application is stored as type-length-value records ... so if your

elf sections are contiguous, there difference between a binary image

and what gets stored in the epcs device will be negligible.

For details, use the force ;-) ... see:

Depending on your image size, you can wrap a secondary loader

around a gzipped image ... and get much better mileage from your epcs :-)

You can nick the gzip code from u-boot or any of several other

source trees.
