[ECOS] problem building redboot - very strange

["Ravi Kumar B S" <ravikbs@mindtree.com>]

hi,

i am facing a problem in building redboot. the redbot is for ARM evaluator 7t
board and i am working on linux 7.1, kernel 2.4.2, gcc 2.95.2(arm-elf-gcc).
i did following things.

ecosconfig new e7t redboot
ecosconfig add flash
ecosconfig tree
make

i got the following error
arm-elf-gcc -mcpu=arm7tdmi -mno-short-load-words -Wl,--gc-sections
-Wl,-static -g -nostdlib

make: *** [build] Error 2

here are certain interesting results.
1. but if i see load.c file there is no occurence of flash_code_overlaps at
all.
2. i am able to build the redboot image if i dont add flash(i.e without
ecosconfig add flash). in this case the build goes fine.
3. but i am able to build redboot with flash support on a different machine
which is using the same tools.

can some body give some clue to fix this problem

regards,

ravi kumar
