I am trying to get physical address of the mipi camera feed for “c” lane and “d” lane.
Is there any way to get access to this raw camera feed?
I tried “v4l2-ctl --list-devies” but it throws back error!
does this mean the driver is already present or not?
Please Help.
Hi,
For the camera basic functionality first needs to check the device and driver configuration.
You can reference to below program guide for the detailed information of device tree and driver implementation.

Please refer to Applications Using V4L2 IOCTL Directly by using V4L2 IOCTL to verify basic camera functionality.

Once confirm the configure and still failed below link help to get log and some information and some tips for debug.

Thanks!
It’s 0x15a10000 = nvcsi base address 0x15a00000 + byte offset 0x10000
Thank you ShanceCCC.
May you please also tell me when and why is the Offset used for?
I just want to be clear that it is not important for the task i am doing!
I am sorry I don’t understand your question.
You can tread it as double word offset.
What could i possibly be doing wrong?
I was reading the address 0x15a10000 = NVCSI base address 0x15a00000 + Byte Offset 0x10000
Do you disable the firewall?
Also you need to launch camera to access NVCSI/VI reg.
