Ov2640 reset eroor on soft reboots about esp32-cam-demo HOT 5 OPEN

I think this was previously mentioned in another issue:
#15 (comment)

For some reason I haven't had issues with reset though. Maybe @Oitzu has some idea.

from esp32-cam-demo.

@igrr I add GPIOs interrupt to the project and find that GPIO can't go to the isr after getting a frame.Before getting a frame ,GPIOs can go to the isr.I try to register isr again but it is no use.

@igrr @Oitzu I fix the bug that ov2640 reset errror. The reg(0xff) of the sensor must be programmed 0x01 after reset the camera.
` gpio_set_level(config->pin_reset, 0);

delay(10);

gpio_set_level(config->pin_reset, 1);

delay(10);

/*after reseting the sensor,the reg (0xff) must be programmed 0x01*/
uint8_t buf[] = {0xff, 0x01};
        twi_writeTo(0x30, buf, 2, true);
        delay(100);
ESP_LOGD(TAG, "Searching for camera address");
/* Probe the sensor */
delay(10);
uint8_t slv_addr = SCCB_Probe();
if (slv_addr == 0) {
    *out_camera_model = CAMERA_NONE;
    return ESP_ERR_CAMERA_NOT_DETECTED;
}
s_state->sensor.slv_addr = slv_addr;
ESP_LOGD(TAG, "Detected camera at address=0x%02x", slv_addr);`

Think you so much! It works!

in the ESP32 Ai thinker CAM there is a reset button does any one know what signal does reset button generates
