OV7670 Camera Driver

sir_hugo

Hi, 

I'm having some trouble getting a device pointer for the OV7670 Camera. I've ported the OV7725 driver. It appears as if the program exits the driver before setting the I2C address:

drv_data->i2c = device_get_binding(DT_INST_BUS_LABEL(0));
printk("HERE!!!!!!!!!!!!!!!!!!!\n");
if (drv_data->i2c == NULL) {
LOG_ERR("Failed to get pointer to %s device!",
DT_INST_LABEL(0));
return -EINVAL;
}
printk("HERE!!!!!!!!!!!!!!!!!!!\n");
drv_data->i2c_addr = DT_INST_REG_ADDR(0);

I'm pretty sure I'm doing something but not entirely sure where.

    I have reviewed your changes and nothing seems to comeout as the culprit for this behavior.

    if you have "zephyr_library()" in your CMakeLists.txt file, and check if your driver is properly initialized. You can do this by starting your program in the debug mode to see if the driver exits with no errors.
