Hello,
I am developing a camera driver on the Jetson platform for a custom camera. I was using Camera Driver Development 2.0 as a guide.
I am not using the ISP since I am using v4l2-ctl to capture test frames. My driver is working correctly on Jetson Nano. For porting to Jetson Xavier NX I created another device tree.
For Nano I was using device tree from imx185 as an example, while for Xavier NX I was using the examples for imx219 (which is originally for two cameras right away, maybe there is the problem).
The sensor format is 10bit, so capturing with v4l2-ctl I am opening the images in python numpy in uint16. Showing the pixels in binary looks like this:
Looking at those values you can see, that only the 7bit in the middle change surrounded by 000 zeroes on both ends. The last 3 bits are always replicate of the first 3 from the middle 7 bit.
0001100000000110
0001101101000110
0001100101000110
0001101110000110
0001100000000110
0001110001000111
0001011110000101
0001101100000110
0001100011000110
0001110011000111
0001100011000110
How come I see such behavior with Jetson NX, but with Jetson Nano it is totally fine? That can only come from different device tree, since my driver source file is the same, right?
Maybe you can have a look at my device trees and tell me what I am doing wrong?
