Update:

Now I can set things like LED.

All you have to do is write a c program, i.e. "ledtest.c"

/* ledtest.c*/# include <stdio.h># include <asm/io.h>
// if you like you can also include the header file with your base addresses of the board
# define LED0 0x06 //the hex address for my first LED
int main(void)
{
  // ... my html code
  outl(LED0, LED_BASE) /* the first parameter of 'outl' is the value you want to set. The second is the base_address of the hardware you want to control. Either insert it manually or take the address from your included header file*/
 return 0;
}

But the most important part is the makefile.

I took it from the generic-cgi folder and modified it to my needs.

You have to add 'O2' to the flags otherwise the header file can't be found.
