Dear Peter Tyser,

Sorry, I'm confused. What exactly do you want me to do? Since you applied Peter's patch, the problem has gone away for me.
However, I think there's still the issue that if there are multiple functions in a standalone application there's no guarantee the entry point function will be at the base of the image. eg if the app were:
That's my understanding as well.
My last question on the issue was: It looks like the -fno-toplevel-reorder flag is only available in gcc >= 4.2 (http://gcc.gnu.org/gcc-4.2/changes.html released May 2007). So, do we add support to U-Boot to conditionally check for the gcc version like Linux to know when to use -fno-toplevel-reorder? Or do we use a linker script that would support more versions of gcc at the cost of more complexity?
I never heard back about the preferred method. I'd personally lean towards checking for compiler version and using the gcc version check + -fno-toplevel-reorder.
Given the fact that GCC 4.2 is already pretty old I also tend to add a gcc version check with -fno-toplevel-reorder instead of increasing the complexity of the linker scripts.
Best regards,
Wolfgang Denk
