This document describes how to test the VIN and CSI2 (only present on Gen3) functionality on Renesas R-Car Gen2 and Gen3.
Get the patches
Ideally all the code to test VIN should be available in renesas-drivers, unfortunate they are not (yet).
For Gen2 testing all that is need is the rcar-vin driver itself and that will soon make its way to the kernel and renesas-drivers, it's currently sitting in media-next.
For Gen3 testing a rcar-vin driver with Gen3 support is needed together with drivers for CSI2 and ADV7482. Prototypes for all these components are public and will soon (hopefully) be available in renesas-drivers. In addition to the drivers DT needs to be set up to hookup these drivers.
To ease the testing all required patches for rcar-vin Gen3 (and Gen2 until it's available in upstream), CSI2, ADV7482, and DT modifications can be found at:
https://git.ragnatech.se/linux rcar-vin-gen3
Boot the kernel
You should see this on successful probe (this is from Gen3):
rcar-vin e6ef0000.video: Device registered as video22 rcar-vin e6ef1000.video: Device registered as video23 rcar-vin e6ef2000.video: Device registered as video24 rcar-vin e6ef3000.video: Device registered as video25 rcar-vin e6ef4000.video: Device registered as video26 rcar-vin e6ef5000.video: Device registered as video27 rcar-vin e6ef6000.video: Device registered as video28 rcar-vin e6ef7000.video: Device registered as video29
Use v4l-utils to test
The v4l2-utils (git://linuxtv.org/v4l-utils.git) provide two tools which are helpful in testing rcar-vin.
qv4l2
A GUI tool which lets you view the video from a rcar-vin device and test a wide range of different input parameters. Start the tool and specifying which video device you wish to operate on using the -d parameter, the video device number for the different video nodes can be observed in the boot log as shown above.
# qv4l2 -d 23
v4l2-compliance
A compliance test tool that verifies the drivers user-space interface. Start the tool and specifying which video device you wish to operate on using the -d parameter, the video device number for the different video nodes can be observed in the boot log as shown above. There are a few other options worth testing, --stream-all-formats (-f) and --streaming=<count> (-s) will test that the driver actually can grab frames in different formats.
