I need to setup the i2c by connecting the camera to the parallel port.
I need to set the camera through i2c writing, but i want to know how to set i2c in i.mx6 saber borad.


example code


int main(int argc, char *argv[])
    int i, j, dev;
    char buf[8];
    if ((dev = open("/dev/i2c-0", O_RDWR)) < 0) {
        perror("open failed");

    if (ioctl(dev, I2C_SLAVE, SLAVE_ADDR) < 0) {
        perror("ioctl failed");


i2c write

write(dev,buf,1) ????????
