camera csi on gpio

[moissan]

Hello, is it possible to connect a csi camera on the A20-OLinuXIno-LIME2
It seems that the allwinner A20 is capable on the banana pi: is it only a question of wiring: cabler the good wires of the gpio on a connector csi

thank you

All of the boards that have an A20 Allwinner processor have CSI camera interface, however the interface comes with a connector in only one of our boards – A20-SOM-EVB. A20-SOM-EVB also comes with a 2MP camera "GT2005" which we also sell separately here: https://www.olimex.com/Products/Components/Camera/CAM-GT2005/ 

The rest of the boards have the pins exposed one way or another but you would need to use wires to access the CSI interfaces. The only thing to care about would be if there is something else connected on the pins of the camera interface (s).

I would recommend you to check about the CSI interface (and CSI0 and CSI1) in the A20 datasheet: https://github.com/allwinner-zh/documents/blob/master/A20/A20_Datasheet_v1.5_20150510.pdf - then inspect the schematics of the boards (the OLinuXino boards are open hardware and there are not only exports of the schematics but the source schematics themselves available)

Best regards,

Thank you, I had seen this camera cheap, but I did not understand how to connect it: so we must draw inspiration from the schema of A20-SOM-EVB  to realize a small card that will make a camera csi interchangeable with other

Yes, use the A20-SOM-EVB source files and the pdf export of the schematic of A20-SOM as a basis.
