[U-Boot] exit(-1) function in U-Boot
Hi all, I am having hard time to find exit() function in U-Boot, so I can exit from a application at any function when something goes wrong.
Is there some alternative? I just want to break program execution, printf message on the screen and regain the prompt.
Salut, Drasko
Dear Drasko,

U-Boot itself has no exit, obviously.
But you mention "application", so I guess you are referring to stand- alone applications; these terminate when you return from the top level function. How you arrange for that is up to you. setjmp / long- jmp are usually trivial to implement / use.
