Hi Jens Thanks for your fast answer. I have some questions befor I try it out: 1. Can I proof, if my gpio is correctly connected with my design or should I try it to proof it? 2. Is the code you send c? If yes, do I need any specific libaries? Then I crosscompile it, put it on my Board and it should work? 3. In edk I saw This at the 4 LEDs: Base Adress: 0x40000000 High Adress: 0x4000ffff How would it be for my case? Something like this:
char *mapped_address = ioremap(0x40000000, 0xffff); writeb(0xffff, mapped_address); iounmap(mapped_address); I don't understand why the there are so many steps between the base and the high adress.
