[ECOS] Red boot package

[ECOS] Red boot package

[Marcin Chrusciel]

I tried to rebuild my ecos with redboot package (after hw template
selecting I change package to redboot) and I got following error:

exceptions   -Wp,-MD,src/main.tmp -o src/redboot_main.o
/tmp/ecos/packages/redboot/current/src/main.c
/tmp/ecos/packages/redboot/current/src/main.c: In function 'cyg_start':
/tmp/ecos/packages/redboot/current/src/main.c:398: error: invalid lvalue
in assignment
/tmp/ecos/packages/redboot/current/src/main.c: In function 'do_go':
/tmp/ecos/packages/redboot/current/src/main.c:598: error: invalid lvalue
in assignment

What do I do wrong? I would be glad for any help.....

What's the target [architecture]?  This problem was discussed a few 
weeks ago and solutions for some architectures are already in CVS.
Look at this thread:

This is a cache macro in my source tree. You need to look at the macro
and recode the assignmnet so that there is no cast on the left hand
side. More recent versions of gcc are disallowing this, where as older
versions do allow it.

No, this variable is properly defined in redboot.h

My guess is that somehow Marcin has touched the files in his build
directory and it didn't get updated properly.  Try 
  % make clean; make

This is a problem with the "reliable" fis update from Alex N. It uses a
variable that does not exit.

Maybe something was missing in the patch?
