[ECOS] help for a ecos beginner

[Michael Anburaj]

Hi Fredrik,

For running any target application (written by you). You need to do the 
following:

1. Build Redboot (ROM start-up configuration) & burn the binary into Flash 
(at 0x00000000)
2. Build the ecos library (RAM start-up configuration)
3. Compile your ecos application & link in with the ecos library (use the 
Makefile under examples as template). This will output the RAM downloadable 
executable (binary or SREC & ELF).
4. Use arm-elf-gdb to load & execute the application.



     |                 _____
     |Target App            |
RAM |    +                 |--- RAM startup image (downloaded into
     |ecos library          |    RAM using Redboot's GDB over serial or ..)
     |                 _____|
-----|----------------------------------------
     |
Flash|redboot with GDB stubs --- ROM startup image (burnt in Flash).

Cheers,
-Mike.

>4.	How would I go about including my own c program in the build?
