The PineCube is a small, low-powered, open source IP camera. Whether you’re a parent looking for a FOSS baby-camera, a privacy oriented shop keeper, home owner looking for a security camera, or perhaps a tinkerer needing a camera for your drone – the CUBE can be the device for you. It features an 5MPx Omnivision sensor and IR LEDs for night vision, as well as Power Over Ethernet, as well as a microphone.

Operating Systems
Armbian
Armbian is a Linux distribution designed for ARM boards. They are usually Debian or Ubuntu flavored.
Download:
Notes:
NixOS
NixOS is a Linux distribution built on top of the Nix package manager using declarative configuration to allow reliable system upgrades.
Buildroot
Elimo Engineering integrated support for the PineCube into Buildroot.
This has not been merged into upstream Buildroot yet, but you can find the repository on Elimo's GitHub account and build instructions in the board support directory readme.
The most important thing that this provides is support for the S3's DDR3 in u-boot. Unfortunately mainline u-boot does not have that yet, but the u-boot patches from Daniel Fullmer's NixOS repo were easy enough to use on buildroot.
This should get you a functional system that boots to a console on UART0. It's pretty fast too, getting there in 1.5 seconds from u-boot to login prompt.

Debugging
Camera issues can be debugged with the gstreamer pipeline. If the camera does not appear to work, it is possible to change the v4l2src to videotestsrc and the gstreamer pipeline will produce a synthetic test image without using the camera hardware.
If the camera is only sensor noise lines over a black or white image, the camera may be in a broken state. When in that state, the following kernel messages were observed:
[ 1703.577304] alloc_contig_range: [46100, 464f5) PFNs busy [ 1703.578570] alloc_contig_range: [46200, 465f5) PFNs busy [ 1703.596924] alloc_contig_range: [46300, 466f5) PFNs busy [ 1703.598060] alloc_contig_range: [46400, 467f5) PFNs busy [ 1703.600480] alloc_contig_range: [46400, 468f5) PFNs busy [ 1703.601654] alloc_contig_range: [46600, 469f5) PFNs busy [ 1703.619165] alloc_contig_range: [46100, 464f5) PFNs busy [ 1703.619528] alloc_contig_range: [46200, 465f5) PFNs busy [ 1703.619857] alloc_contig_range: [46300, 466f5) PFNs busy [ 1703.641156] alloc_contig_range: [46100, 464f5) PFNs busy
Camera Adjustments
Focus
The focus of the lens can be manually adjusted through rotation. Note that initially, the lens could be tight.
Low light mode
To get imagery in low-light conditions you can turn on the infrared LED's to light up the dark area and also enable the IR cut filter using the commands below. Note that these were performed on Armbian using the instructions from here [1].
# Run these as root # Turn on the IR LED lights (note that you can see a faint red glow from them when it's low light) # Turn them off with echo 1 instead (this may be inverted depending on the version of the kernel you have) # echo 0 > /sys/class/leds/pine64\:ir\:led1/brightness # echo 0 > /sys/class/leds/pine64\:ir\:led2/brightness # Export gpio, set direction # echo 45 > /sys/class/gpio/export # echo out > /sys/class/gpio/gpio45/direction # Enable IR cut filter (note that you can hear the switching noise) # Disable with echo 0 instead # echo 1 > /sys/class/gpio/gpio45/value
Camera controls
It is possible to adjust the camera using certain internal camera controls, such as contrast, brightness, saturation and more. These controls can be accessed using the v4l2-ctl tool that is part of the v4l-utils package.
# List the current values of the controls
v4l2-ctl -d /dev/v4l-subdev* --list-ctrls
User Controls
contrast 0x00980901 (int) : min=0 max=255 step=1 default=0 value=0 flags=slider
saturation 0x00980902 (int) : min=0 max=255 step=1 default=64 value=64 flags=slider
hue 0x00980903 (int) : min=0 max=359 step=1 default=0 value=0 flags=slider
white_balance_automatic 0x0098090c (bool) : default=1 value=1 flags=update
red_balance 0x0098090e (int) : min=0 max=4095 step=1 default=0 value=0 flags=inactive, slider
blue_balance 0x0098090f (int) : min=0 max=4095 step=1 default=0 value=0 flags=inactive, slider
exposure 0x00980911 (int) : min=0 max=65535 step=1 default=0 value=4 flags=inactive, volatile
gain_automatic 0x00980912 (bool) : default=1 value=1 flags=update
gain 0x00980913 (int) : min=0 max=1023 step=1 default=0 value=20 flags=inactive, volatile
horizontal_flip 0x00980914 (bool) : default=0 value=0
vertical_flip 0x00980915 (bool) : default=0 value=0
power_line_frequency 0x00980918 (menu) : min=0 max=3 default=1 value=1
Camera Controls
auto_exposure 0x009a0901 (menu) : min=0 max=1 default=0 value=0 flags=update
Image Processing Controls
pixel_rate 0x009f0902 (int64) : min=0 max=2147483647 step=1 default=61430400 value=21001200 flags=read-only
test_pattern 0x009f0903 (menu) : min=0 max=4 default=0 value=0
# Set the contrast controls to the maximum value
v4l2-ctl -d /dev/v4l-subdev* --set-ctrl contrast=255
You can see which flags can be changed and which ones cannot by looking at the flags. The inactive flag indicates that it is currently disabled. Some of these flags are disabled when other flags are turned on. For example, the gain flag above is inactive because gain_automatic is enabled with a value of "1." Note that at the current time the auto_exposure flag is inverted, so a value of "0" means on, while "1" means off. Maybe the auto_exposure flag will get changed someday. You'll need to turn off auto_exposure (value=1) if you want to manually set the exposure flag.
Sound Controls
Note that sound is only currently available with special patches on top of a 5.13.13 or higher kernel with Armbian or NixOS. Once you have a kernel that supports sound you can install alsa-utils to get the alsamixer tool. The following mixer settings have been found to work with both playback and record. Note that you'll need to press F5 to get the capture controls and space bar to turn on/off capture for a device. The speaker dangles on a wire from the device. The microphone is located about 1cm below the lens on the front facing circuit board.

Unpack SDK and then compile and pack the image:
7z x 'PineCube Stock BSP-SDK ver1.0.7z' mv 'PineCube Stock BSP-SDK ver1.0' pinecube-sdk cd pinecube-sdk/camdroid # apply SPI Flash patch above or edit m25p80.c file source build/envsetup.sh lunch # select [1] here mklichee extract-bsp make -j3 pack
Compile using Vagrant
You can avoid setting up your machine and just use Vagrant to spin up a development environment in a VM.
Just clone the Elimo Engineering repo and follow the instructions in the readme file
After spinning up the VM, you just need to run the build:
cd pinecube-sdk/camdroid # apply SPI Flash patch above or edit m25p80.c file source build/envsetup.sh lunch # select [1] here mklichee extract-bsp make -j3 pack
Flashing the image
See PhoenixCard for a manual on how to flash Allwinners BSP images.
