#include<assert.h>
int main(int argc, char **argv)
{
volatile unsigned short * complete;
volatile unsigned char * lsb, * msb, * control;
int res;
int fd = open("/dev/mem", O_RDWR);
assert(fd != -1);
lsb = control = (unsigned char *)mmap(0, getpagesize(),
PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x10c00000);
msb = lsb + 1;
complete = (unsigned short *)mmap(0, getpagesize(),
PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x10800000);
*control = 0x41;
while ((*complete & 0x80) == 0);
res = *lsb;
res |= *msb << 8;
printf("result: %d\n", res);
close(fd);
return 0;
