Raspberry Pi MIPI Camera calibration

#1

We have been trying to get imx219 raspberry pi camera to work on rockpi for quite some time. While it somewhat works on Debian out of the box (you own test_camera.sh script for example), rkcamsrc refuses to take calibration xml file from /etc/cam_iq/imx219.xml. Without it the color balance is all screwed up and the image is GREEN. We are using the latest debian patched with https://wiki.radxa.com/Rockpi4/radxa-apt.

Example of a working(green) gstreamer pipeline:

gst-launch-1.0 rkcamsrc device=/dev/video0 io-mode=4 isp-mode=0A ! videoconvert ! video/x-raw,format=NV12,width=1920,height=1080 ! jpegenc ! multifilesink location=%d.jpg

Example of a pipeline with xml calibrations that should work according to https://github.com/rockchip-linux/gstreamer-rockchip-extra, but doesn’t:

gst-launch-1.0 rkcamsrc device=/dev/video0 io-mode=4 isp-mode=2A tuning-xml-path=/etc/cam_iq/imx219.xml ! videoconvert ! video/x-raw,format=NV12,width=1920,height=1080 ! jpegenc ! multifilesink location=%d.jpg

Error log on the latter pipeline:

gst-launch-1.0 rkcamsrc device=/dev/video0 io-mode=4 isp-mode=2A tuning-xml-path=/etc/cam_iq/imx219.xml ! videoconvert ! video/x-raw,format=NV12,width=1920,height=1080 ! jpegenc ! multifilesink location=%d.jpg

And then this RKISP1 error repeats until you ctrl+c gstreamer.

Image sample. That bottom cup is pure white by the way.

Any help?

Dunno there is a script in overlay-debug/usr/local/bin/test_camera-rkisp1.sh

Which have been updated in https://github.com/rockchip-linux/rk-rootfs-build

Prob needs https://github.com/radxa/rk-rootfs-build but the Rockchip master just misses the Raxda Wifi/BT firmware patch.

I am not that great with Git as its prob real easy to pull the up to date rockchip and apply the firmware patch.
I would just pull that repo and copy and paste the patch… :slight_smile:

I’m also looking for support with camera. I have two platforms witk RK3399: Rockpi 4 and some other SOM, tried to get ov13850 and imx219. I’m able to get them detected, but I’m stuck with greenish images :frowning:

I think I tried rkisp, rkcamsrc and rkv4l2src plugins, all without success. Does anyone here had success with any camera module and rk3399? Somehow on Android it works.
