I want to use an address named _end from the linker.ld file in main.c.
I know this address to be atleast 0x80000000. But when importing it like this extern char _end; in main.c and printing it I only get 17.
The linker.ld file is something like this :

SECTIONS {
    . = 0x80000000; 

/*some more code and sections (doesnt matter)*/

    _end = .;
}

Does anyone why this is happening or how I should import _end?
Thx in advance, jip.
