[U-Boot-Users] sc520 problems with objcopy

I've been porting to an sc520 based board and I've had several compiler and
linker issues which I think I have solved. The problem now is that objcopy
never finishes and uses all available memory. I have to kill the process
otherwise it starts to try and use all virtual memory as well.
I did a system call trace, and from it you can see that it gets to a point
where it is calling brk() and from this it never seems to end.
Has anyone else had this problem? Is it a problem caused by linker/compiler
settings? Any clues would be appreciated!
