Dear NXP Community Members,
I hope this message finds you well.
I am currently developing a new camera sensor device driver using the i.MX 8M Plus EVK on Linux Yocto (version 6.1.55). The device I am working with is referred to as "a123". I have used the ov5640 sensor driver as a reference to create the device tree source file (.dts) and the driver file (.c). However, upon loading the kernel module, a new /dev/video interface is not being created.
In the dmesg log:
* "mx8-img-md: Registered mxc_isi.0.capture as /dev/video3" indicates it is registered as /dev/video3.
* "unregister ISI channel: mxc_isi.0" yet it seems to be unregistered.
Could you please advise on what might be required to successfully create the /dev/video device?
Here is my current status:
* The dmesg log is attached for your reference.
* I have verified I2C communication using the i2cdetect command; I2C read/write operations are successful from a user application.
Thank you for your assistance.
Best regards,
Sakata
