RE: [ECOS] Simple serial program

["Trenton D. Adams" <tadams at extremeeng dot com>]

Ok, thanks.  I'll try it both with RedBoot, and from ROM on it's own.  I
need to know that it's working.  However, I can't find anywhere in the
eCos documentation or build tool documentation on how to select the type
of program, RAM or ROM!

You almost certainly have built it for RAM startup. It should be built
for "ROM" startup (which means to run from Flash).

You could also use RedBoot to program the flash, which is what I was
referring to before - you don't have to use dl_edb7xxx.
