Nios2 eclipse IDE, objcopy data segment

This topic has already been discussed at least in here:

forum topic (http://forum.niosforum.com/forum/index.php?showtopic=1880&pid=7553&mode=threaded&show=&st=&#entry7553)

I was able to link the object to the memory image file by adding the object file name to the linker command options.

If the object file has been successfully linked, it should appear in the project.map file.

How to tell the linker to make a map file is discussed here:

map file entry (http://forum.niosforum.com/forum/index.php?showtopic=312&pid=1232&mode=threaded&show=&st=&#entry1232)

And from the c/c++ code i can access the memory are by accessing it as an array type.

_binary_test_txt_start is a symbol in the .map file.

extern char _binary_test_txt_start[];
