[Nathan Sinclair]

Followed instructions in 327 instructions for raspberrypi

1. enabled legacy mode in bullseye raspi
2. ran ./veye_raspipreview -v -t -1 -p '0,0,1920,1080'
3. ran ./veye_raspistill -o ./test.jpg

here's the verbose output for the 2 commands

./veye_raspipreview -v -t -1 -p '0,0,1920,1080'

@veye_xumm It reports i2c information, sensor is imx462, but i still couldn't get a preview of the camera.

Is this the board you're using? I'll try it.

The feedback from this link below is the same as your problem, and although it is in Chinese, the images in it are informative.

I'll list the points to use:

1. Use a separate 5V supply.
2. On the raspberry pi zero 2w, the power on enable pin for camera, needs to be executed separately:

 raspi-gpio set 40 dh

Once this is done, the camera can be detected on the i2c-10 bus.

 i2cdetect -y 10

The 0x3b device can be detected and the script can read and write camera parameters now.
After completing the above steps, you can use the veye_raspicam series software normally.
