Can't have simultaneously IMX519 and Hawkeye camera with CM4

Hello, I’m trying to use simultaneously the mini IMX519 camera and the 64MP Hawkeye camera on a Compute Module 4.

When I connect each individual camera by themselves, they work fine, but when I use them both, it doesn’t work at all. I have tried:

  • Plugging the mini camera by itself with dtoverlay=imx519,vcm=off and it works fine.
  • Plugging the 64MP camera by itself with dtoverlay=arducam-64mp and it works fine.
  • Plugging both the mini and the 64MP:

I tried the following:

dtoverlay=imx519,vcm=off,cam0
dtoverlay=arducam-64mp,cam1

and:

dtoverlay=arducam-64mp,cam0
dtoverlay=imx519,vcm=off,cam1

But I keep getting No camera available!.

Does anyone have an idea what I could be missing? Thanks!

Hi,
You can try the setup below:

  • imx519 to CAM 1 port and Hawkeye camera to CAM 0 port.

  • Use the following:

dtoverlay=imx519,vcm=off
dtoverlay=arducam-64mp,cam0

Wow, this actually works, that’s pretty strange… Thanks anyways!
