Hello,

This is an extension of an ongoing issue I have documented on the main Raspberry Pi Forum:  
[https://forums.raspberrypi.com/viewtopic.php?t=324820&start=25](https://forums.raspberrypi.com/viewtopic.php?t=324820&start=25)

In short:  
It seems there is an issue with the Hyperpixel display and the HQ Camera working together in the latest version of Pi OS Lite ( 64bit )

With both connected to the Pi, there are instances after bootup where the camera is not detected by the OS, showing this error:

```auto
pi@raspberrypi:~ $ dmesg | grep imx
[6.737814] imx477 10-001a: failed to read chip id 477, with error -5
[6.738922] imx477: probe of 10-001a failed with error -5

```

Even upon several reboots you will get that same error…however every so often; the issue will be gone and the camera is detected:

```auto
pi@raspberrypi:~ $ dmesg | grep imx
[6.826154] imx477 10-001a: Device found is imx477
[6.827145] imx477 10-001a: Consider updating driver imx477 to match on endpoints

```

If anybody has an experience with this, or a similar issue and found a fix; please advise as this is an issue that is project breaking ramifications in my case.

> I cannot seem to get the IMX477 HQ Camera to work in tandem with the Hyperpixel …under Raspbian OS ( Bullseye )

> The overlay for the imx477 is required now given how cameras are operated with Raspbian using Libcamera.  
> 
> As it described above, the LCD + Touch works, however the camera is not even detected by the system and Libcamera apps fail to run:

> ERROR: \*\*\* no cameras available \*\*\*\`
> 
> I believe the Hyperpixel is interfering with the i2c on the HQ camera which I believe is exposed via the GPIO pins. Has anyone found a fix or work around for this?
