[ts-7000] Re: TS-7800 green LED woes

["craignied" <>]

I got it to work.  For those who may be new to the TS-7800, compiling the 
following

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/mman.h>
#include <fcntl.h>
#include <assert.h> 
#include <string.h>
#include <signal.h>

int main( int argc, char **argv )
{
        volatile unsigned char *start;
        volatile unsigned int *LED;
        int fd = open( "/dev/mem", O_RDWR|O_SYNC );
        assert(fd != -1);
        
        start = mmap( 0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd, 
0xE8000000 );
        LED = ( unsigned int * )( start + 0x8 );
        *LED = 0x40000000;

        close( fd );
        return 0;
}

with gcc LED.c -o LED

and running

sudo ./LED
(or just ./LED if you're root)

Will turn on the green LED.
