how to use the CSI2-MIPI interface.it is not detecting. what are the configurations I have to do?
I am using the ov5640 camera, when I connect this camera to the CSI1-MIPI interface, the camera works.
suppose I connect to the CSI2-MIPI interface, it is not working. what is the reason? if anyone knows please help me out.
Thanks &Regards

Hi @srinivas_123!
Yes, that is correct.
You can check the device trees saved on the memory using the next commands:
"fatls mmc 1:1" for SD card boot
"fatls mmc 2:1" for MMC boot

Hi Srinivas,
You could first check the CSI2-MIPI node in the device-tree. Check if there is a node for the ov5640 camera for the CSI2-MIPI and the state is set to "okay".
If the ov5640 camera does not have a node in the CSI2-MIPI you can try create it based on the node for the CSI1-MIPI.

Hi @srinivas_123!
Thank you for contacting NXP Support!
For iMX8MP you should set the device tree called "imx8mp-evk-basler-ov5640.dtb" or "imx8mp-evk-os08a20-ov5640.dtb"
