Kernel headers for 5.11.10 / 5.7.10 - BPI-M2Z (server)

Kernel headers

Extract the files in /usr/src/ path

cd /usr/src/
sudo tar -xf linux-headers-5.11.10-server.tar.gz

Ubuntu 20.04 LTS - Kernel 5.7.10 / 5.11.10 - BPI-M2Z

Ubuntu 20.04 LTS (focal)

This is the Ubuntu 20.04 LTS Image for bpi-m2z with kernel 5.7.10 and 5.11.10, where you can switch between the two in /boot partition:

• eth0 (if you wired the ethernet connector)
• wlan0 (wifi)
• BT (not tested)
• OV5640 (camera)
• server like with the minimum size, suitable for robotics/testing/fun with latest features from the stable kernel (kernel.org)

Credentials

ubuntu / ubuntu

Wifi

The wifi / ethernet manager is the netplan which runs great in the focal disto.

• before you boot:

  edit the file /etc/netplan/01-netcfg.yaml and change your ssid (FIBER-8784) and password,
  do not change the layout or use TABs

• first login:

    sudo apt-get update
    sudo apt-get dist-upgrade
    sudo netplan apply
  

PS: watch for any message or error, if you change the layout it will spit some messages

• Reconfigure locale (Language settings)

    sudo dpkg-reconfigure
  

• Reconfigure keyboard layout

   sudo dpkg-reconfigure keyboard-configuration
  

Flashing OS Image to SD CARD

You will need a Linux box to flash the image to sd card. Any size of the sd card will fit. Suggested > 8GB.

Instructions:

• find your sd card device, if you have a USB card reader it will be in the form of /dev/sdX where X is a letter (b,c...), if you have an sd card reader (native), it will be in the form of /dev/mmcblkY where Y is a number from 0,1,2...10
  make sure you find the correct device or you may end formatting your hard disk....

• run the commands:

sudo chmod +x format_sd_mainline.sh (make it exec)
sudo chmod +x flash_sdcard_mz2_focal.sh (make it exec)

then

    ./format_sd_mainline.sh /dev/sd**X** or /dev/mmcblk**Y**
    ./flash_sdcard_mz2_focal.sh /dev/sd**X** or /dev/mmcblk**Y**

after it finished, remove the sd card and boot the board with the sd card inserted.

Issues

Yet to find... board runs HOT, around 60 ºC while using wlan and ethernet, use a good heat-sink.

Switching kernel versions

You can choose the kernel by changing the links in /boot file:

To boot with kernel 5.7.10:
lrwxrwxrwx 1 root root 32 mar 28 12:46 bpi-m2-zero.dtb -> bpi-m2-zero-v4.dtb_5.7.10-server
lrwxrwxrwx 1 root root 20 mar 28 12:46 zImage -> zImage_5.7.10-server*

To boot with kernel 5.11.10:
lrwxrwxrwx 1 root root 33 mar 28 18:36 bpi-m2-zero.dtb -> bpi-m2-zero-v4.dtb_5.11.10-server
lrwxrwxrwx 1 root root 21 mar 28 18:35 zImage -> zImage_5.11.10-server*

How to change:

     cd /boot
     sudo ln -sf bpi-m2-zero-v4.dtb_5.11.10-server bpi-m2-zero.dtb
     sudo ln -sf zImage_5.11.10-server zImage
     sudo reboot

Ubuntu 20.04 LTS - Kernel 5.11.10 - BPI-M2Z

Ubuntu 20.04 LTS (focal)

This is the Ubuntu 20.04 LTS Image for bpi-m2z with kernel 5.11.10 and with the following kernel config enabled:

• eth0 (if you wired the ethernet connector)
• wlan0 (wifi)
• BT (not tested)
• OV5640 (camera)
• server like with the minimum size, suitable for robotics / software testing / fun with latest features from the stable kernel (kernel.org)

Instructions:

• find you sd card device, if you have a USB card reader it will be in the form of /dev/sdX where X is a letter (b,c...), if you have a sd card reader (native), it will be in the form of /dev/mmcblkY where Y is a number from 0,1,2...10
  make sure you find the correct device or you may end formatting your hard disk....

• run the commands:

sudo chmod +x format_sd_mainline.sh (make it exec)
sudo chmod +x flash_sdcard_mz2_focal.sh (make it exec)

then

    ./format_sd_mainline.sh /dev/sd**X** or /dev/mmcblk**Y**
    ./flash_sdcard_mz2_focal.sh /dev/sd**X** or /dev/mmcblk**Y**

after it finished, remove the sd card and boot the board with the sd card inserted.

Issues

Currently, there are no issues reported, but bear in mind this kernel runs really HOT, it is like 5 ~ 10 ºC higher when wifi and ethernet are connected / in use. I suspect is the GPU with the wrong frequency and have not found how to solve it, yet.

Latest Fix

The file sources.list (/etc/apt/sources.list) has wrong contents (x86) and should be overwritten with the correct one (armhf).
Please copy the correct file sources.list to /etc/apt/ prior to boot first-time. If you already booted, copy the file and issue a:

    sudo apt-get update
    sudo apt-get dist-upgrade

ignore the warnings

CPU Temp Optimization

The CPU Temp throttling occurs at 75ºC in order to be run inside a case but if you have a good heat-sink you can use the new bpi-m2-zero-v4.dtb_5.6.13-server that starts throttling at 80ºC which has a better performance. Thermal throttling is now at 80ºC.

instructions

1 - Login (shell cmd)
2 - cd /boot
3 - sudo mv bpi-m2-zero-v4.dtb_5.6.13-server bpi-m2-zero-v4.dtb_5.6.13-server-BAK
4 - sudo wget https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/download/v3.6/bpi-m2-zero-v4.dtb_5.6.13-server
5 - sync && sudo reboot

BananaPi M2 Zero - Ubuntu 19.10 - Kernel 5.6.5 Server

Kernel 5.6.5 Server BananaPi M2 Zero - Ubuntu 19.10 - EOAN

This is the Mainline Kernel 5.6.5 Server, ideal for building packages, developing applications and kernels on board, and installing a small Desktop if you desire.

No cedrus or mail in this kernel. That means, no HW acceleration.

Install instructions

This kernel is meant to be installed in Ubuntu 19.10 Image

• Make a backup as usual

• run in the shell

    sudo dpkg -i linux-image-5.6.5-server_1.0-43.deb
  

U-boot M2Z (bootloader)

U-boot optimized for M2Z

New U-boot to speed-up boot time.

While running the board type in the shell:

wget https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/download/v3.4/booloader_m2z.bin
sudo dd if=./booloader_m2z.bin conv=notrunc bs=1k seek=8 of=/dev/mmcblk0
sync
sudo reboot

Speed up login process

If you are not using ethernet (eth0) you can speed up the login process by adjusting the file /etc/network/interfaces with

• install he'd (sudo apt-get install jed)

• edit the file and make eth0 static IP like this:

  sudo jed /etc/network/interfaces

change and save the eth0 portion:

auto eth0
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0
broadcast 255.255.1.255
