RE: [ECOS] Linking problem with redboot for cme555

["Eric Castle" <ecastle at umich dot edu>]

We did the following using the 2.0 ecosconfig and 2.0 pre-built tool chain,
with the CVS repository:

1) ecosconfig new cme555 redboot
2) import redboot_ROM.ecm
3) fixed an unresolved conflict by adding CYGPKG_CRC by typing:
    ecosconfig add CYGPKG_CRC
4) ecosconfig tree
5) make

This gets us the following error: "redboot.elf section .bss is not within
iram region"

It seems to be trying to write outside of the internal RAM and into external
memory, which starts at 0x00400000.

What steps did you follow to configure RedBoot?  Is this using the CVS
tree?
