The ORPSoC model is designed to load an initial image into Flash memory at start up. When debugging with GDB it is more usual to use the debugger to load a particular image into RAM. So the initial flash image is just a simple program which initializes the caches, then sits in a tight loop. It may be found in the sw/loop directory and makes use of the OpenRISC 1000 utilities in sw/utils and the library in sw/support.

The directory sw/test-progs contains a series of programs for loading into RAM by GDB. The programs are:
