camera init failed on esp-eye board

[gozfree]

I have updated esp32-homekit-camera code, and make flash to esp-eye board, but seems camera init failed:

...
E (11963) ledc: requested frequency and duty resolution can not be achieved, try reducing freq_hz or duty_resolution. div_param=3
E (11983) camera_xclk: ledc_timer_config failed, rc=ffffffff 
SCCB_Write [ff]=01 failed
SCCB_Write [12]=80 failed
E (12013) camera: Camera probe failed with error 0x20001
E (12013) esp32_camera: Camera init failed with error 0x20001
...

sensor is OV2640, could you help me

0x20001 is "camera not detected" error. Looks like it can not detect it on I2C bus. Since it is a stock module, make sure you have set correct camera module in menuconfig:
ESP32 HomeKit Camera -> Camera Pins -> Select Camera Pinout -> ESP_EYE DevKit.

If that does not work, please post a photo of your quick reference card found inside packaging. It looks something like this:

Oh, I haven't noticed the other error: ledc timer initialization failure. Looks like there is a problem with esp32-camera module which still haven't caught up with ESP-IDF changes. Try solution from there: put a timer_conf.clk_cfg = LEDC_USE_APB_CLK; line after this line

I have already select "ESP_EYE DevKit" but it does not work. And my quick reference card is the same with your two pictures.

Thanks! It works after adding clk_cfg.
But homekit seems crash after configuration:
