MangoPi R3 - 0.2 Camera FW + fswebcam - JPG Images all green

I have an MangoPi R3 with an OV2460 camera plugged in to the 24 Pin DVP connection - with the 0.2 camera FW installed.

 

When I use the pre-installed fswebcam tool to take JPG photos - all the images are green with some minor details. Here is an example, I have tried many different arguments to fswebcam - even using just the defaults 

 

Example  command line

 

fswebcam -r 320x240 tester.jpg

 

Output image

 

I uploaded the 0.2 camera FW, the docs mention that the camera is not compatible with other 0.2 SPI FW - which doesnt make sense as the FW is on the SPI Flash and only accessed at boot). I used the following binaries - all downloaded from the web (none of these have been built by me)

 

CameraFWv0.2\output\images\u-boot-sunxi-with-nand-spl.bin

CameraFWv0.2\output\images\devicetree.dtb

CameraFWv0.2\output\images\rootfs.ubi

CameraFWv0.2\output\images\zImage

 

 

I used Windows 10 and the F1C_SPI_NAND_Flash_Tool_V0.3exe to upload the config.

 

Thanks

By the way - I have tried with 2 different OV 2460s cameras - both of which work perfectly in other devices.
