BananaPi M2 Zero - Ubuntu Xenial Base Minimal Image (Experimental) - U-Boot 2017.09 / Kernel 4.19.y (mainline - stable)
The Image comes with the minimum packages but you can install a full Desktop on top of this, see how at the end.
This is a WiP, a bare minimum firmware image (CLI - command line interface) with basic configurations. Kernel used is Mainline kernel 4.17.y / 4.18.y / 4.20.y / 5.3.y / 5.6.y / 5.7.y / 5.11.y with some patches applied. The idea behind this firmware is to have a very basic sd card image and add packages to your need. Kernel 5.7.10 / 5.11.10 has support for OV5640.
-
v1 is Kernel 4.15.y
-
v2 is Kernel 4.17.y
For convenience, an 8GB SD CARD Image is at https://mega.nz/#!obIAVQiA!G0CCABkLunCcG8hEqMf7NfjTBK1jgMytt2f0VdtOl08
Use 7zip to unzip it and flash it with etcher or win32imagewriter (Win32DiskImager)
-
v2 stable kernel 4.17.12 update
sudo dpkg -i linux-image-4.17.12-m2z_1.0-5.deband then:
sync && sudo shutdown -h now
power cicle the board
-
v3 stable kernel 4.18.4 upgrade
sudo dpkg -i linux-image-4.18.4-m2z_1.0-7.deband then:
sync && sudo shutdown -h now
power cicle the board
- v4 stable kernel 4.18.8 upgrade
Before upgrade, get rid of old kernel image not in use and check available space in /boot
df -lh
Filesystem Size Used Avail Use% Mounted on
/dev/mmcblk0p2 15G 631M 13G 5% /
devtmpfs 183M 0 183M 0% /dev

/dev/mmcblk0p1 93M 64M 23M 74% /boot
Make sure you have enough free space left, if not, issue in shell:
sudo dpkg -l | grep linux-image

ii linux-image-4.18.6-m2z-otg-gadget 1.0-11 armhf Linux kernel 4.18.6-m2z-otg-gadget
and check the current kernel you are running:
uname -r
4.18.6-m2z-otg-gadget
so it is safe to get rid of unused kernel and free some space for the new one you want to install:
sudo dpkg -r linux-image-4.17.12-m2z
(Reading database ... 35990 files and directories currently installed.)

v13 mailine kernel 4.20.17-m2z (experimental) upgrade
https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v13
This kernel is provided as a POC where you can build Kodi
Attention
The mali blobs used for the mali GBM are not compatible with the mali FBDEV You are required to update the mali with the wayland mali to be able to use GBM
Mainline stable kernel 4.20.17 ready to build Kodi:
- Cedrus (VPU)
- Mali (GBM)
- hdmi-sound
- wifi + eth
- tools to test cedrus and gbm (pre-built)
To test mali GBM you can run kmscube To test cedrus you can run v4l2-request-test
Testing cedrus on mainline is quite simple, run the tests below:
cd v4l2-request-test
sudo ./v4l2-request-test -l -f 25 -P ed-mpeg2
or
sudo ./v4l2-request-test -l -f 25 -P caminandes-h265
To test mali GBM you need to setup the mali blobs provided by https://github.com/bootlin/mali-blobs
sudo ./kmscube
When you run the kmscube you will see a cube spinning
To be able to acess and output sound to HDMI you need to update the file /etc/asound.conf
pcm.!default {
type plug
slave {
pcm "hw:1,0"
}
}
ctl.!default {
type hw
card 1
}
Reboot and test the HDMI sound:
sudo aplay /usr/share/sounds/alsa/Front_Left.wav
Check for the codecs:
cat /proc/asound/cards
0 [Codec ]: H3_Audio_Codec - H3 Audio Codec
H3 Audio Codec
1 [allwinnerhdmi ]: allwinner_hdmi - allwinner,hdmi
allwinner,hdmi

wireless-regdb: Missing support for kernel direct loading
This seems to affect ubuntu 16.04 and 18.04.
To do before first boot:
- edit /etc/network/interfaces and add your SSID and password in order to use connect to your Wifi
Generate wpa-psk for Wifi AP, you can use wpa_passphrase from your linux box
Generate like so:
wpa_passphrase SSID 01234567890
where SSID is your Wifi SSID and 01234567890 your password
Edit and change accordingly:
iface wlan0 inet dhcp
wpa-ssid SSID
#psk="1234567890"
wpa-psk 93c8ff514dc02ae4944f89424d7b0d94f42ab3245cc413755ab655b8e344a2d9
dns-nameservers 8.8.8.8 8.8.4.4
wireless-power off
To do after first boot (Advanced users):
* build regulatory.db to your country for the wifi to get full power
* re-build wireless-regdb
-
Board runs at ~60ºC when idle with HDMI, ~40ºC without HDMI enabled (without heatsink)
-
issue in shell on first login: sudo apt-get update && sudo apt-get upgrade
It is always a good idea to issue a: sudo shutdown -h now (and wait for the Red led Heartbeat to stop and only then unplug power)
-
If you have trouble with Wifi, i suggest read Debian Bug report logs - #892229
Regulatory.db needs to be generated somehow, until wireless-regdb is updated or rebuild it yourself.
-
You need a linux box
-
You need a good SD CARD reader/writer (External SD CARD Reader are known to not be reliable) Read some heated up discussion on Armbian's forum about how to write to SD CARD
-
Get a trusted brand for the SD CARD
-
insert your SD CARD into SDHC reader/writer:
check which device is your SD CARD, type in shell:
dmesg | tailAn output of USB SDHC reader/writer card

-
format the sd card:
in the example above, our sd card device is sdc (could be sdb)
sudo ./format_sd_mainline.sh /dev/sdcor /dev/mmcblk0 if you have SDHC reader on your laptop for example
sudo ./format_sd_mainline.sh /dev/mmcblk0
-
flash Image to sd card (ssh enabled):
cat rootfs_kernel_4.17.y.tar.gz.* > rootfs_kernel_4.17.y.tar.gz sudo ./flash_sdcard_m2z_v2.sh /dev/sdc
-
flash Image to sd card:
sudo ./flash_sdcard_m2z.sh /dev/sdc -
flash Image with ssh enabled to sd card:
sudo ./flash_sdcard_m2z_ssh.sh -
Booting first time
Before you boot, configure your wifi
Wifi use wpa_supplicant to connect to AP. Before you boot the Image, please edit /etc/network/interfaces
iface wlan0 inet dhcp

wait untill it finish with "Done setting line discpline" (CTRL+C to end) and then:
hciattach /dev/ttyS1 any
We should have now our Bluetooth ready, you can check:

We are going to test our bluetooth setup conecting our board to a Phone (pair with a Phone). In a Desktop environment we have Blueman which would do it automagically but installing it would require a lot of packages and our goal here is to have the minimum installed otherwise you go with a complete Desktop.
For this, it is necessary to install pulseaudio or you will not be able to connect to a phone. (i think for keyboard or mouse is ok without pulse).
In order to have pulseaudio working we need to install ALSA and make it work.
sudo apt-get install alsa-utils alsamixer libasound2 alsa-base
Edit (or create) a file /etc/asound.conf with the content:
pcm.!default {
type hw
card 0
device 0
}
ctl.!default {
type hw
card 0
}
sync && reboot.
Check device:
aplay -l

We can check if ALSA is working, type in shell:
alsamixer
and un-mute and turn up the Line up and everything
and review:
sudo amixer

Now check if pulse is running:
ps -e|grep pulse

Here are the instructions for building your own kernel on board.
-
Install tools
sudo apt-get install git bison flex bc device-tree-compiler -
Get a Kernel with support for this board, for example mainline kernel 5.2.0 or your own
-
Get the patch or patch set and apply to your kernel if your kernel is not complete
-
Get mali support from Bootlin
-
Watch linux-sunxi for the latest changes and fixes
Create directory:
mkdir -p linux
cd linux
export KVD=$PWD
Grab your kernel (here we get linus torvalds kernel 5.2 as an example): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/refs/tags
wget https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/snapshot/linux-5.2.tar.gz
tar -xvpzf linux-5.2.tar.gz
cd linux-5.2
Build:
make sunxi_defconfig
#make menuconfig (if you want to add or change kernel modules)
make oldconfig
make INSTALL_MOD_PATH=output zImage
make INSTALL_MOD_PATH=output dtbs
make INSTALL_MOD_PATH=output modules
make INSTALL_MOD_PATH=output modules_install
export KV=$(strings ./arch/arm/boot/Image |grep "Linux version"|awk '{print $3}')
make INSTALL_HDR_PATH=output/usr/src/linux-headers-${KV} headers_install
Install:
sudo cp -vfr ./output/* /
sync
sudo cp -fv ./arch/arm/boot/zImage /boot/zImage_${KV}
sync
sudo cp -fv ./arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dtb /boot/bpi-m2-zero.dtb_${KV}
sync
Make it current kernel
cd /boot
sudo ln -sf zImage_${KV} zImage
sudo ln -sf bpi-m2-zero.dtb_${KV} bpi-m2-zero.dtb
cd ${KVD}
sync
Reboot
sudo reboot
You can add or change kernel modules at any time and modify your dts to get the hw peripherals to work properly. From now on you are at your own.
There is support for camera in mainline kernel. You can use a USB camera or the OV5640 camera (DVP). In general, USB camera are slower than the DVP camera, you can stream video at 20 FPS with DVP camera and 10 FPS for the USB camera. The quality of the image is highly dependent on the lens used. Using a sensor without AF is recommended if you use mainline kernel.
- USB camera
- OV5640 DVP camera
USB Camera
Once you attach the USB camera you will see the device node representing the camera, that is:
ubuntu@bpi-m2z:~$ ll /dev/video*
crw-rw---- 1 root video 81, 0 Apr 11 2019 /dev/video0
crw-rw---- 1 root video 81, 1 Apr 11 2019 /dev/video1
crw-rw---- 1 root video 81, 3 Nov 8 13:29 /dev/video2
crw-rw---- 1 root video 81, 4 Nov 8 13:29 /dev/video3
and media information in:
ubuntu@bpi-m2z:~$ ll /dev/media*
crw-rw-rw- 1 root video 243, 0 Apr 11 2019 /dev/media0
crw-rw-rw- 1 root video 243, 1 Apr 11 2019 /dev/media1
crw-rw-rw- 1 root video 243, 2 Nov 8 13:29 /dev/media2
To find about the topology of the camera you would do:
ubuntu@bpi-m2z:~$ media-ctl --device /dev/media2 --print-topology

We have our HD 720P USB camera attached to the USB 2.0 slot. The kernel created /dev/video2 and /dev/media2 nodes for us. You can test the streaming with USB camera using mjpg_streamer like this:
mjpg_streamer -i "./input_uvc.so -d /dev/video2 -r 1280x720 -q 90 -n" -o "./output_http.so -p 8088 -w ./www"
OV5640 DVP camera
Testing video streaming with OV5640 requires you to tell kernel the window size and format of the frame unless you use the default 640x480 Pixels in size and YUV420P format
In our example we find the frame format our DVP sensor can be used:

In order to get maximum speed and optimization for streaming a video we use the MJPEG format that delivers a compressed JPEG image to be sent over the Wifi. We need an optimized mjp_streamer which will grab the image and send MJPEG to the browser at the other side.
-
Tell kernel we want MJPEG and 720P
media-ctl --device /dev/media1 --set-v4l2 '"ov5640 3-003c":0[fmt:JPEG_1X8/1280x720]' -
Stream the video at port 8080
mjpg_streamer -i "./input_uvc.so -d /dev/video2 -r 1280x720 -q 90 -n" -o "./output_http.so -p 8080 -w ./www" -
