I thought that apps built with arm-elf tools would still work though? They
just wouldn't be optimised for xscale.

Oh he was trying to build eCos programs. In that case the problem is bound
to be that he is reusing the same build tree and configuration and just
expecting it to work.

In that case what Venkat needs to do is start over *in a new build
directory*. Including rerunning "ecosconfig new iq80310" or whatever it is
he wants to do now, and then editting the ecos.ecc to change
CYG_HAL_STARTUP to have a user_value of ROM.
