OV5640 in Nano PI duo 2

[scizors]

Hi,
I am using OV5640 in Nano PI duo 2

 

kernal:
Linux nanopiduo2 5.10.16-sunxi #21.02.2 SMP Sun Feb 14 21:12:17 CET 2021 armv7l armv7l armv7l GNU/Linux

 

I found that NanoPi Duo2 - FriendlyARM WiKi which is kernal 4.14 supports camera OV5640.

 

Do  Armbian Focal (mainline based kernel 5.10.y) have support?

 

if not Please say how to do it? I am new to this armbian kernal 

 

Thanks in advance

Do we have support for OV5640 in NanoPIduo2?

quick check

You can follow this thread and add the ov5640 overlay, use the ov5640 params from FE dts node.

Hi,
How can I enable OV5640 driver in order to have ov5640.ko driver to be loaded

 

 

Thanks and regards

Make sure you have at least these kernel configs enabled:

 

CONFIG_I2C_GPIO=m
CONFIG_V4L_PLATFORM_DRIVERS=y
CONFIG_VIDEO_SUN6I_CSI=m
CONFIG_V4L_MEM2MEM_DRIVERS=y
CONFIG_VIDEO_MEM2MEM_DEINTERLACE=m
CONFIG_VIDEO_OV5640=m

Hi lex,

 Thank you for the kernal configs. I did that

 

After that what should I need to change in  sun8i-h3-nanopi-duo2.dts. AS I am using Nnao pi duo 2 with H3 chipset running under armhf(32bit) Armbian Focal (mainline based kernel 5.10.y) 

 

Thanks in advance
