i2cdetect is reporting UU for address 0x10, which means the Linux kernel drivers are loaded for imx219.

The kernel CSI2 driver and firmware CSI2 driver can not co-exist, and the firmware should back off from touching the CSI2 receiver if it sees the kernel has it enabled. Remove camera_auto_detect=1 and dtoverlay=imx219 (if present) from config.txt to stop the kernel drivers from being loaded.

Also the kernel will have assigned the address 0x10 to the imx219 driver, so other clients should get an EBUSY error. It looks like I've been naughty when I wrote this and used I2C_SLAVE_FORCE which ignores the fact that another client is already registered. That was a very bad move on my part.

I will ask why you're trying to use raspiraw. It is deprecated (README is now updated) as we have full Linux kernel drivers for imx219 and the CSI2 receiver. Those should be used in preference to raspiraw.

yes!its fix
Hello @6by9 ,I try to capture up to 1000fps video in 1024*10 by raspberrypi
as I fix this problem , I found a lot problem, such as I cannot crop with v2camera 、I cannot film long time video by circle stroage in this app .
and the latest problem is open the .raw file.

May I ask should I try another app to do this video(1000fps)? such as the Linux kernal(is this one?https://github.com/raspberrypi/linux/tree/rpi-5.4.y)
or which app should l do is better for my sittuation?

thanks
