Below picture is MIPI CSI schematic in i.MX95LP4XBB-15. We need to configure reset pin, enable pin and MCLK for OV5640. These changes can be done in device tree. Linux-6.12-enable-ov5640-on-mx95-evk.patch is the patch.
After apply the patch and run mx95 with imx95-15x15-evk-adv7535-ov5640.dtb, we can list the camera device
root@imx95evk:~# cam -l
Available cameras:
1: 'ov5640' (/base/soc/bus@42000000/i2c@42540000/ov5640_mipi@3c)
To capture camera image into a file, use below command
