[ECOS] building ROM stub for RAM image- EDB7212

[AshCan at aol dot com]

A while back Gary Thomas sent me a GDB stub that set up the MMU to make use of the internal SRAM of the EP7212 since I was using an image loaded to board DRAM.

Can anyone help me with instructions on how to build the stub so I can add functionality to it?

I see that ecos.ecc wants me to build a ROM image with stub or RAM image and use the stub Gary provided for me. From what I can see I can not build the stub based on a RAM image.

The reason I want to create my own stub is that I want to add a boot loader to the stub.  I want my stub to read an image also stored in flash ROM and copy the image to DRAM since DRAM is faster in cases of cache misses.  

thank you,
