OV5640 on Colibri IMX8


I am testing a Toradex OV5640 camera module with an IMX8 Colibri SOM and cannot seem to get it working. I have connected the camera and checked dmesg for bootup and see the following info about the mipi_csi

colibri-imx8x-06558488:~$ dmesg | grep mipi
[    0.038603] mipi0_dsi_power_domain : no governor for states

Any help would be appreciated. Thks

Greetings @bigmc,

Just so I have the information before I start investigating what version of the i.MX8X module are you using and what version of Torizon are you running? You can get the Torizon release version via the output of cat /etc/issue.

The version of iMX8 is,


and the Torizon version is,

TorizonCore 4.0.0-devel-202004+build.3


Alright I believe I found out what the issue was here. The support for the OV5640 was added after the version of TorizonCore you currently have installed. By next week we plan to release a more up-to-date monthly build for this module. This release should have the OV5640 support.

As a small note when you install A more recent TorizonCore versions do be careful. There are images for the i.MX8QXP 1.0B and then there are images for the i.MX8QXP 1.0C. Due to silicon differences these images are not compatible with one another so make sure to read the description of the image in Easy Installer to make sure you are installing software for the 1.0B. Worst case if you install software meant for 1.0C you’ll need to recover your device back to Easy Installer as it will “soft brick”.

Best Regards,
