NanoPi/Cam500B/Mainline status

[g40]

Greetings. For anyone interested FriendlyArm have a Github repo which contains a working AW CSI driver. and has device tree files for NanoPi M1+ and Neo Air. 

 

See https://github.com/friendlyarm/linux.git. The branch is sunxi-4.16.y

 

This is a work in progress but the setup is vastly simplified compared to the VFE subsystem in the 3.4/3.10 kernels. The OV5640 driver does produce video but I'm getting some odd images at the moment. Possibly colorspace related.

 

As a bonus USB OTG is also working ...
