BPI -M2 Zero + Ultra Camera (OV5640) Modprobe: Fatal Module not found

Banana Pi SBCs design BPI-M2+/BPI-M2 Zero/BPI-P2 Zero(H3)

HI

I am complete noob, I installed: 2017-12-04-Armbian_5.36_Bananapim2zero_Ubuntu_xenial_next_4.14.3_desktop_preview_build_by_bpi.img as my flash.

I am trying to install (.ov5640) ultra camera onto my Banana pi BPI_M2 zero. I run the sudo modprobe ov5640 command and then get

modprobe: FATAL: Module ov5640 not found in directory /lib/modules/4.14.3-sunxi

please could someone tell me what is wrong

CSI / VFE is not ready on kernel 4.14.x, you need to use kernel 3.4.x

Thank you for your reply. I installed kernel 3.4.x as suggested.

I then ran following commands;

sudo modprobe ov5640 sudo modprobe sun8i_csi0

The first command ran with no error but second command gives error: fatal: module not found in /lib/3…4.x-sun8i

I have also tried sudo modprobe sun8i_csi and sudo modprobe sun8i_csi

First thing to check is if your Image has support for Camera (OV5640), that means the script.bin has OV5640 setup in it. I believe the MATE Image with the right bpi-tools will load OV5640/CSI at the boot time.

There is no sun8i_csi module and a load of the following modules would suffice to have camera working IF script.bin has ov5640 configuration:

   ov5640
   vfe_v4l2

You can check that after loading the two modules:

dmesg|grep ov
dmesg|grep OV
dmesg|grep VFE

if you don’t see error then you have success and can use your camera

Very nice!

Do you plan to make you hardware extension available? If you do, please, reverse the reversed CSI pin at the sensor end and we can have a professional solution (more camera lens) and by the photos seems you plan night vision?
