How to properly set up ov2718 camera module?

[DWD]

1)   show modules.conf & mpp.conf file from:   PROJECT_DIR/out/eagle/lindeni-v5/debian/target/etc/modules-load.d/
2)   show  modules.order  file and  list of the all files in directory:  PROJECT_DIR/out/eagle/lindeni-v5/debian/target/lib/modules/4.4.55+/


P.s:  "Did you try to boot your Lindenis board using the official image: http://wiki.lindeni.org/index.php/Linbia...he_SD_card ?"

I use emmc official image.

modules.conf:

Code:

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

mpp.conf:

Code:

videobuf2-dma-contig
vin_io
#imx317_mipi
ov2718_mipi
vin_v4l2
sunxi_aio

As you can see, I manually commented out imx module and inserted ov.

Yesterday, I was reading the source file of ov2718_mipi.c more carefully and noticed that a lot of registers it attempts to write to does not exist in the ov2718 manual!
So now I am skeptical about the quality of the driver and maybe register set for 1080p mode is wrong. I will investigate about it more and return if I get any results.

P.S. There's a suggestion for you to use Sochip's image - I would advise you against it.
The reason is that sochip uses different kind of RAM (if I remember correctly) and therefore different voltage. You may damage your Lindenis if you don't correct the sys_config.fex in Sochip's image first.
