Board Identification

under process

(TODO)

Using the following node, you can get the 16-digit board ID.

cat /sys/class/efuse/usid

odroid@odroid64:~$ cat /sys/class/efuse/usid
HKC2123456789ABC

$ gcc -o get_usid get_usid.c

odroid@odroid64:~$ ./get_usid 
S/N is 'HKC2123456789ABC'

get_usid.c

#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
 
#define SYSFS_CLASS_USID        "/sys/class/efuse/usid"
#define USID_LEN        16
 
int main(int argc, char *argv[])
{
        int fd, len;
        char buf[USID_LEN];
 
        fd = open(SYSFS_CLASS_USID, O_RDONLY);
        if (fd < 0)
                printf("Open error! \n");
 
        read(fd, buf, USID_LEN);
 
        printf("S/N is '%s'\n", buf);
 
        close(fd);
 
        return 0;
}

Or the unique MAC can be used to define your board.

odroid@odroid64:~$ ip add | grep link/ether
