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!

Looking at past posts, it looks like the sc520 port is in bad shape. I tried compiling sc520_spunk and sc520_cdp and they are missing so many files and have some so many linker problems (due to missing files and broken linker script) It looks like some PCI stuff must have disappeared along the way somewhere too ...

I removed the --gap-fill=0xff and I was able to create an srec file. I think objcopy was spending all its time filling in 0xff ... I don't know if it works yet, but at least I was able to complete a make.

Perhaps the sc520_xxxx ports should be marked as "incomplete" or "broken"?
