This will work, but you have to use a *different* IP address
for the RedBoot/GDB connection than you use for the eCos code.

The proper approach is:
  % ecosconfig new edb7xxx redboot
  % ecosconfig import ${ECOS_REPOSITORY}/hal/arm/edb7xxx/current/misc/edb7212_redboot_ROM.ecm 
  % ecosconfig tree
  % make
(or the equivalent ConfigTool steps)

This should build a version of RedBoot virtually identical
to the prebuilt image you've already used.
