[ECOS] Linking problem with redboot for cme555

[ECOS] Linking problem with redboot for cme555

[Eric Castle]

Hello Andre,

I’m Eric Castle, a student at the University of Michigan.  I am currently
working on FEGI, which is a student project that is designing and building a
payload for a space mission.

We have been trying to get RedBoot into the internal flash of the MPC555 on
the Axiom CME555 board.  Currently, we’re getting an error almost identical
to the one that was posted to the eCos-discuss list last year:

“address 0x4030e4 of .../bin/redboot.elf section .bss is not within region
iram”

We were wondering if and how you had resolved this issue?  

My current idea would be to try cutting stuff from RedBoot, but I don’t know
what I can safely remove.

Thanks,

-Eric Castle

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?
