BananaPi M2 Zero - Ubuntu Xenial Base Minimal Image (Experimental) - U-Boot 2017.09 / Kernel 4.19.y (mainline - stable)

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 with some patches applied. The idea behind this firmware is to have a very basic sd card image and add packages to your need.

The Image comes with the minimum packages but you can install a full Desktop on top of this, see how at the end.

  • 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.deb
    

    and 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.deb
    

    and 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
	tmpfs           248M     0  248M   0% /dev/shm
	tmpfs           248M   11M  237M   5% /run
	tmpfs           5.0M     0  5.0M   0% /run/lock
	tmpfs           248M     0  248M   0% /sys/fs/cgroup
	/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-4.17.12-m2z           1.0-5                                      armhf        Linux kernel 4.17.12-m2z
	ii  linux-image-4.17.8-m2z            1.0-1                                      armhf        Linux kernel 4.17.8-m2z
	ii  linux-image-4.17.9-m2z            1.0-2                                      armhf        Linux kernel 4.17.9-m2z
	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.)
	Removing linux-image-4.17.12-m2z (1.0-5) ...

and now install the latest kernel:

	sudo dpkg -i linux-image-4.18.8-m2z-otg-gadget_1.0-12.deb
	Selecting previously unselected package linux-image-4.18.8-m2z-otg-gadget.
	(Reading database ... 33740 files and directories currently installed.)
	Preparing to unpack linux-image-4.18.8-m2z-otg-gadget_1.0-12.deb ...
	INFO: Updating Kernel 4.18.6-m2z-otg-gadget to 4.18.8-m2z-otg-gadget
	INFO: Updating...

	Setting up linux-image-4.18.8-m2z-otg-gadget (1.0-12) ...
	OK: Kernel upgrade success! Please reboot with: sync && sudo reboot

and then:

	sync && sudo reboot 

or better

	sync && sudo shutdown -h now

power cicle the board and check kernel version again:

	uname -r 
	4.18.8-m2z-otg-gadget
  • v5 mailine kernel 4.19.0 upgrade

Mainline stable Kernel 4.20.17 (Kodi)

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

VPU 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

Mali GBM test

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

hdmi-sound

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

  has given some tips to fix this issue.
* Debian Bug report logs - #892229
  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

Tips

  • 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.

Basic instructions to flash firmware to SD CARD

  • 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 | tail
    

    An output of USB SDHC reader/writer card

    Your device will be in the form of: /dev/sdX where X is your sd card letter (b,c,d...) or /dev/mmcblkY where Y is your device number (0,1,2...)

  • format the sd card:

    in the example above, our sd card device is sdc (could be sdb)

      sudo ./format_sd_mainline.sh /dev/sdc
    

    or /dev/mmcblk0 if you have SDHC reader on your laptop for example

      sudo ./format_sd_mainline.sh /dev/mmcblk0
    

Image v2 (Kernel 4.17.4)

  • 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
    

Image v1 (Kernel 4.15.y)

  • 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

Connecting to AP via Wifi

Wifi use wpa_supplicant to connect to AP. Before you boot the Image, please edit /etc/network/interfaces

iface wlan0 inet dhcp
wpa-ssid SSID <== change this
#psk="1234567890"
wpa-psk 93c8ff514dc02ae4944f89424d7b0d94f42ab3245cc413755ab655b8e344a2d9 <== change this

  • Login first time

You can login with

user: ubuntu

pasw: ubuntu

via serial debug or use ssh to connect remotely from your computer.

Conecting via ssh or putty: ssh ubuntu@IP where IP is the IP assigned to the board.

First thing you should do on the first login (for v1 only)

  • fix mv segment fault

    sudo apt-get install --reinstall coreutils

  • fix missing service

    sudo apt-get install --reinstall systemd

  • disable power management

    sudo iwconfig wlan0 power off

or in /etc/network/interfaces add this entry:

allow-hotplug wlan0
  iface wlan0 inet dhcp
  wpa-ssid your_ssid
  #psk="12345678901234567890"
  wpa-psk ababaf514dc02ae4944f89424d7b0d94f42ab3245cc413755ab655b8e344a2d9

reboot now:

sudo reboot

Mali benchmark

You can benchmark mali for fbdev, type in shell:

cd /home/ubuntu/mali/mali-fbdev/build/src
sudo ./glmark2-es2-fbdev

You can add FRONTBUFFER_LOCKING=1 to prevent tearing before running benchmark:

export FRONTBUFFER_LOCKING=1

Installing a Full Desktop environment

After you setup a connection to internet, you can install a Desktop environment

sudo apt-get update
sudo apt-get dist-upgrade
sync
sudo apt-get install lxde

Wait until it finished and issue:

sync
sudo shutdown -h now (wait for the heartbeat to stop and cut power)

Reboot and you have LXDE Desktop

Bluetooth

The latest Kernel 4.20.0-rc3 upgrade has Bluetooth working. To be able to use bluetooth follow this instructions (it should be automated via systemd service but for the sake of documentation we do it manually) :

  • Install packages

      sudo apt-get install rfkill bluez bluetooth-touch
    
  • Load hci_uart kernel module

Edit the file /etc/modules and add bluetooth & hci_uart & rfcomm:

	# /etc/modules: kernel modules to load at boot time.
	#
	# This file contains the names of kernel modules that should be loaded
	# at boot time, one per line. Lines beginning with "#" are ignored.
	#xradio_wlan
	g_serial
	#xradio_wlan
	brcmfmac
	bluetooth
	hci_uart
	rfcomm
  • Boot with the new /etc/modules

  • in shell type:

      sudo su (to become root)
      brcm_patchram_plus -d --patchram /lib/firmware/ap6212/bcm43438a1.hcd --enable_hci --bd_addr 11:22:33:44:55:66 --no2bytes --tosleep 5000 /dev/ttyS1
    

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:

	hcitool devi

Bluetooth - How to pair a Bluetooth Phone with command line

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
	**** List of PLAYBACK Hardware Devices ****
	card 0: Codec [H3 Audio Codec], device 0: CDC PCM Codec-0 []
	  Subdevices: 1/1
	  Subdevice #0: subdevice #0

We can check if ALSA is working, type in shell:

	alsamixer
	and un-mute and turn up the Line up and everything

and review:

Testing ALSA:

	aplay /usr/share/sounds/alsa/Front_Center.wav             
	Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

Now install pulse:

	sudo apt-get install pulseaudio pulseaudio-module-bluetooth

sync && reboot.

Now check if pulse is running:

	ps -e|grep pulse
	1187 ?        00:00:00 pulseaudio

If everything is OK (if not, you should go back and figure out what went wrong) we can now pair with a phone using bluetooth. Type in shell (if you have not done this yet):

And finally you can check the Services of your Bluetooth Phone:

	dptool browse 00:17:CA:F7:38:18|grep "Service Name"
	Service Name: Generic Access Profile
	Service Name: Generic Attribute Profile
	Service Name: Audio Source

	Service Name: Network service
	Service Name: SMS/MMS Message Access
	Service Name: Email Message Access

Enbale Bluetooth on next boot (permanently)

To enable Bluetooth (BT) for every new boot, edit /etc/rc.local and add the command:

	#!/bin/sh -e
	#
	# rc.local
	#
	# This script is executed at the end of each multiuser runlevel.
	# Make sure that the script will "exit 0" on success or any other
	# value on error.
	#
	# In order to enable or disable this script just change the execution
	# bits.
	#
	# By default this script does nothing.
	
	# ------------------------
	# ------ enable BT -------
	# ------------------------
	# borrowed from madscientist42
	# Compute a BD_ADDR.  We're going to use pieces of the device serial number for the LAP part.
	SERIAL=`cat /proc/device-tree/serial-number | cut -c9-`
	B1=`echo $SERIAL | cut -c3-4`
	B2=`echo $SERIAL | cut -c5-6`
	B3=`echo $SERIAL | cut -c7-8`
	BDADDR=`printf b8:27:eb:%02x:%02x:%02x $((0x$B1 ^ 0xaa)) $((0x$B2 ^ 0xaa)) $((0x$B3 ^ 0xaa))`

	# -- BT end --------------
	
	exit 0
	#!/bin/bash

Make sure /etc/rc.local has run permissions:

	sudo chmod +x /etc/rc.local

Build your own Kernel

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.

Credits

Kernel 4.20.0-rc3 is based on mainline kernel (https://www.kernel.org/) (linux-sunxi effort).

Mali based on MRipard (Bootlin)

Thanks to Nora Lee (FOXCONN) for the sample.
