Strange linker problem after updating binutils and gcc

Strange linker problem after updating binutils and gcc

[Jan Pohanka]

Hello,
I'm using gcc with binutils in Rowley Crossworks for ARM 1.7 IDE for
arm development. Unfortunately there is very old version of gcc
(4.1.1) and binutils (2.17) in this IDE, so I decided to upgrade to
gcc 4.4.4 and binutils 20.20.51 (I tried more versions but all are
affected)

Unfortunately there is a problem with linking in new version.
In first try, linker generated warning "dot moved backwards before..."
so I solved it with proper ordering of sections in ld script,
unfortunately there is still an error because the generated elf file
is wrong - some data are written in high addresses, resulting bin file
has size of 500MB instead of 500kB.

ld is invoked with following params:

ld -X -nostdlib -ereset_handler --omagic --fatal-warnings -EL
-Te:/_dev/_kamera/JR1_git/_tmp_JR615 Flash Debug/JR615 Flash
Debug.1.8.23.2.h263.ld -Map _JR615 Flash Debug//JR615 Flash
Debug.1.8.23.2.h263.map -u_vectors -o _JR615 Flash Debug//JR615 Flash
Debug.1.8.23.2.h263.elf --start-group ...

and ld script:

Re: Strange linker problem after updating binutils and gcc

Hi Jan,

Have you tried generating a linker map file (-M command line to ld) and 
then looking in this to see what is being stored at the high addresses ?

Cheers
