Dear Yocto community
I have a custom camera driver and device tree that I include in my Yocto build
for a raspberry pi 4 along with Libcamera.
The camera module has been tested on a RPi with Raspbian OS and it works fine
there. I have a custom camera_helper and tuning file, that also works as
intended (tested using the Libcamera cam app to stream to display).
The camera module seems to be loaded correctly through the Yocto image on the
raspberry pi 4, as it is listed using "lsmod" and video0 is also there using
v4l2-ctl commands.
But using the cam app "cam -l" to list camera modules, it returns no camera
modules are found. I include Libcamera as such:
IMAGE_INSTALL += "libcamera"
And I use an append file to copy my meson build file for the camera helper and
tuning file along with the files themselves:
FILESEXTRAPATHS:prepend := " ${THISDIR} /files:"
SRC_URI += "file://camHelper/cam_helper_myCam.cpp \
file://camHelper/meson.build \
file://tuningFile/ myCam.json \
file://tuningFile/meson.build"
do_configure:append() {
cp $ {WORKDIR} / camHelper / cam_helper_myCam.cpp $ {S} / src / ipa /
raspberrypi /
cp $ {WORKDIR} / camHelper / meson.build $ {S} / src / ipa / raspberrypi /
cp $ {WORKDIR} / tuningFile / myCam.json $ {S} / src / ipa / raspberrypi / data
/
cp $ {WORKDIR} / tuningFile / meson.build $ {S} / src / ipa / raspberrypi /
data /
}
I see that the files appear in the correct location in my build, but for some
reason Libcamera doesn't find my camera device. Is there something I am missing
in my configuration file?
Kind regards
