Subject: [PATCH 2/2] arm64: dts: imx8mn-evk: Add camera support
Date: Sat, 15 Jul 2023 20:02:09 -0300 [thread overview]
Message-ID: <20230715230209.221504-2-festevam@gmail.com> (raw)
In-Reply-To: <20230715230209.221504-1-festevam@gmail.com>
From: Fabio Estevam <festevam@denx.de>
Add support for the OV5640 camera.
Tested with the following commands:
media-ctl -l "'ov5640 2-003c':0 -> 'csis-32e30000.mipi-csi':0 [1]"
media-ctl -V "'ov5640 2-003c':0 [fmt:UYVY8_1X16/640x480 field:none]"
media-ctl -V "'crossbar':0 [fmt:UYVY8_1X16/640x480 field:none]"
media-ctl -V "'mxc_isi.0':0 [fmt:UYVY8_1X16/640x480 field:none]"
v4l2-ctl --device /dev/video0 --set-fmt-video=width=640,height=480,pixelformat=YUYV
v4l2-ctl --stream-mmap -d /dev/video0;
gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! waylandsink
