[Bug]: Example not working: opencv_camera_test.elf

[KrystofVydra]

What happened

opencv_camera_test.elf produces blank output on the HDMI screen and also blank images taken from camera. The fastboot app, that also takes realtime camera capture and displays it on HDMI works. Only the OpenCV implementation doesn't. In the log, it say that "d" is invalid option.

Reproduction steps

1. Compile opencv_camera_test.elf following tutorial: https://github.com/kendryte/k230_docs/blob/f99a29267ee3ca0353cf94a42e68d80aa14f0acb/en/01_software/board/middleware/K230_OpenCV_Sensor_Usage.md

2. copy the compiled opencv_camera_test.elf file to sharefs.

3. run the opencv_camera_test.elf app on the big core as specified in the tutorial:
   ./opencv_camera_test.elf -D 101 -m 0 -d 0 -s 24 -c 0 -f 0 -W 1920 -H 1080

Hardware board

CanMV K230 v1.1

Software version

k230 SDK v1.8

Anything else

Here I attach both opencv_camera_test.elf and fastboot_app.elf logs:
