[U-Boot-Users] i had some problem in uboot1.1.1

[刘会田]

i was a freshman in developing sbc8260 board.
  i got a led_light program for testing boot ,and set some register right in
cpu_init_f. Why the uboot could not boot successed?
another questions:what purpose about env_init?
 Thanks!
 static int led_light(void)
 {
int i,j;
char *k=0x21000000;
char ki[8]={0,4,2,6,1,5,3,7};
int l=0;
for(i=0;i<=7;i++)
{
for(j=1;j<100;j++)
{
l++;
}
*(k+ki[i])=0x80;
for(j=1;j<5000000;j++)
{
l--;
}
*(k+ki[i])=0x0;
return(0);
 }
}
