kandi X-RAY | MIPI_Camera Summary
The MIPI cameras are widely used nowadays for smartphones and many opensource platforms like Raspberry pi and Nvidia Jetson series boards. And in order to add more mipi cameras (or other video streaming device with MIPI interface) support for these maker hardware platforms while keeping the mipi camera complex interface and protocol hidden from the user, Arducam team developed several camera drivers and demo codes based on different driver frameworks and their implementations.

QUESTION
I'm trying to add ADV7282-m support to a linux kernel build with Yocto. However I cannot seem to get it to work. I have gotten the module to load and detect the chip.
The driver completely makes it through the probe
but there is no v4l device created.
The board i'm trying to get it to run on is a VAR-SOM-DUAL, with an IMX6 CPU. I manually added the ADV7282-m (going by examples found with google) to the device tree, but i'm not sure if this is correct because i'm not very familliar with device tree's:
...ANSWER
Answered 2019-Oct-23 at 09:39I got the ADV working. Apparently I completely misunderstood the ADV7180 driver. It only creates the V4L subdevice, which can then be used by a bridge-driver to get the /dev/video0 device. I used the driver given in thisthread and made it work in my linux kernel version. After doing this all worked as expected.
QUESTION
I am using i.m6QUAD with hummingboard2 (hummingboard Gate) with 3.14.79 linux kernel from this site GitHub - SolidRun/linux-fslc: Linux kernel source tree
It's been a loong time since i am playing with ov5642 parallel camera and I can't get it to work...
As i see on schematic of hummingboard I can use parallel camera using IPU2_CSI1.
I set up device tree as this:
-in file "imx6qdl-hummingboard2.dtsi" (this file contains common part fo quad and dual-lite) I set up v4l2 to use IPU2/CSI1:
...ANSWER
Answered 2017-Mar-28 at 12:20Ok. The solution was obious - to remove used pin defclaration in imx6qdl-hummingboard2.dtsi file. However I don't know why in my first try of removing pins my linux didn't want to boot up (so I rejected this solution as not working).
