arducam ar0230
kernel module compile:
cd /usr/src
git clone https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver
cd Arducam-Pivariety-V4L2-Driver/src
make
make -C /lib/modules/`uname -r`/build M=$PWD
make[1]: *** /lib/modules/5.10.17+/build: No such file or directory. Stop.
make: *** [Makefile:10: default] Error 2
apt-get install raspberrypi-kernel-headers
(populates the /lib/modules/`uname -r`/build directory)
cd /usr/src/Arducam-Pivariety-V4L2-Driver/src
make
mkdir /lib/modules/5.10.17+/kernel/drivers/video/arducam
cp arducam.ko /lib/modules/5.10.17+/kernel/drivers/video/arducam
depmod
modprobe arducam
...and nothing happens. Weird.
on reboot, dmesg shows messages from overlay:
[ 33.130812] arducam_vddl: disabling
[ 33.130852] arducam_vdig: disabling
[ 33.130878] arducam_vana: disabling
(manual modprobe)
[ 111.097100] arducam: loading out-of-tree module taints kernel.
(indeed, the AR0230 is not supported.)
let's try the other one...
cd /usr/src
git clone https://github.com/ArduCAM/Arducam_OBISP_MIPI_Camera_Module
cd Arducam_OBISP_MIPI_Camera_Module/sourceCode
...makefile is not there, so...
cp /usr/src/Arducam-Pivariety-V4L2-Driver/src/Makefile .
make
...and it spits some errors. but produces a .ko file. so,
cp arducam.ko /lib/modules/5.10.17+/kernel/drivers/video/arducam
depmod
and make the overlay,
we can do
cd dts
dtc -O dtb -o arducam.dtbo arducam-overlay.dts
but we'll try first to use the existing binary,
cp ../Release/bin/5.4.51+/arducam.dtbo /boot/overlays/
it worked. we uncommented some printk from the kernel, too.
this one is supporting these cams:
13MP AR1335 high-resolution camera
2MP AR0230 HDR camera
"And Sony starvis IMX290, IMX327 camera will come up very soon."
