Hello,
Relating to my previous post, I have been trying to added the STEVAL-66GYMA to RPI5 according to the manual. Then, I successfully got video streaming through rpicam-hello command.
To change the MIPI data lane number, I edited device tree source files. I changed the data-lane to <1> from <1 2> at fragment@3 and fragment@4 in vd16gz_vd56g3_vd66gy-overlay.dtsi as below. After compiling it, I confrmed the video streaming was avairable.
Then, I want to ask whether my procedure is enough for changing the MIPI data lane number. Do I have to change any other settings? Also, I would like to know how I can check that the MIPI data lane number was changed.
I tried to get the register value of the image sensor by using i2cget command from RPI5 terminal, but I couldn't get the value.
Any comments for this issue will be appreciated.
