Sorry for missing veyecam2m.dtbo, please try this new release package.

https://github.com/veyeimaging/raspberrypi_v4l2/releases/tag/v1.27

@jambojettt
I suspect you haven't seen the most important document, which is the link below. Generally, you don't need to compile the driver yourself. Instead, you can simply install the driver by following part4 in the link below. Specifically, the command you need to execute is: sudo ./install_driver.sh veyecam2m

@jambojettt
show me the result of this cmd:

dmesg | grep veye

@jambojettt

Please try this released version again. This time it will work.

@brunosaisi Sorry, there was a parameter type mismatch issue in this part before. Please update the code from the following link:
https://github.com/veyeimaging/raspberrypi_v4l2/tree/main/i2c_cmd/source

@brunosaisi
Sorry for the late reply. Please navigate to the i2c_cmd/source directory, run ./make.sh, and then try again. Your camera is connected to i2c-10, so you can use -b 10 as the parameter.

@brunosaisi
Please show me the result of this:

dmesg | grep veye

This can reveal which specific I2C bus your camera is on.

@jambojettt
Sorry for reply late.
I see that your raspberrypi-kernel-headers are installed. You should be able to directly run make in the driver source code directory.

@jambojettt
Normally, the PiOS you installed comes with kernel-headers. Could you tell me which image link you used?
Can you help run this script and send me the results?

uname -a
ls /usr/lib/modules/
ls /usr/lib/modules/$(uname -r)

@jambojettt said in Can't get v4l2 to work, rasbperry pi 4b, rpi os x64, 6.12.57-v8+:

@veye_xumm yes, it updated to 6.12.57, but this problem also was in 6.12.47 that it was updated from.
How do I get the headers?

My Raspberry Pi comes with headers by default. You might want to reinstall piOS? We've already released the 6.12.47 ko file on GitHub.
