Introduction

BPI-M2M

Overview: BPI-M2M ubuntu linux
  Banana Pi M2M is another ARM SoC powered development board that offers great computing performance in an ultra portable form factor. It is a 51mm square with Allwinner A33 Quad-core A7 SoC and 512MB DDR3 RAM.

Key Features

  • Quad Core ARM Cortex A7 CPU. R16
  • 512MB DDR3 SDRAM
  • WiFi (AP6212) & Bluetooth onboard

Development

Android

 1.You could download latest image from our forum.
 
 2.Put your TF card into a TF-USB adapter, and then plug adapter in your Windows PC usb interface.
 
 3.Prepare your image, and download image burning tools PhoenixCard.exe.
 
 4.Use "PhoenixCard.exe" to burn android image to TF card.

Linux

Prepare

1. Prepare 8G/above TF card, USB-Serial cable.
2. Connect USB-Serial to 40 pin header uart2 for kernel console debug.
Note: three pin header uart0 beside usb port is not debug uart for bpi release images because SDcard and uart0 are multiplex pin and default bpi images support both SD and eMMC. If you want bootup with emmc only and enable uart0 as debug port without SDcard support, please refer to enable uart0 debug for emmc only image section.

3. Install bpi-tools on your Linux PC, If you can't access this URL or any other problems, please go to bpi-tools repo and download this tools manually.
 $ apt-get install pv
 $ curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
4. Download latest linux image, and confirm that the md5 checksum is correct.
5. Defautl login: pi/bananapi or root/bananapi.

Install Image to SDcard

1. Install image with bpi-tools on Linux, plug your sd card to your Linux PC
   $ sudo bpi-copy  xxx-bpi-m2m-xxx.img.zip /dev/sdX
2. Install image with dd command on Linux, umount SDcard device /dev/sdX partitions if mounted automatically, Actually bpi-copy is the same as this dd command.
   $ sudo apt-get install pv
   $ sudo unzip -p xxx-bpi-m2m-xxx.img.zip | pv | dd of=/dev/sdX bs=10M status=noxfer
3. Install bpi image with Etcher on Windows, Linux and MacOS
Balena Etcher is an open source project by Balena, Flash OS images to SD cards & USB drives

Install Image to EMMC

1. Prepare a SDcard with Linux image flashed and bootup the board with this SDcard.
2. Copy emmc image to udisk, plugin the udisk to board and mount it.
3. Install with bpi-tools command
   $ sudo bpi-copy xxx-bpi-m2m-xxx.img.zip /dev/mmcblk1
4. Or Install with dd command, umount mmcblk1p1 and mmcblk1p2 partition if mounted automatically, Actually bpi-copy is the same as this dd command
   $ sudo apt-get install pv
   $ sudo unzip -p xxxb-bpi-m2m-xxx.img.zip | pv | dd of=/dev/mmcblk1 bs=10M status=noxfer
5. After flash complete, power off safely and eject the sdcard.

Note: If the emmc was flashed android image before, you must erase the boot partition of android before step 3 or step 4.

Build Source Code

1. Get the bsp source code
 $ git clone https://github.com/BPI-SINOVOIP/BPI-M2M-bsp
2. Build the bsp source code
Please read the source code README.md

Advance Development

Enable uart0 for emmc only image debug

1. Enable uart0 node and disable sdc0 node in sunxi-pack/sun8iw5p1/configs/BPI-M2M-LCD7/sys_config.fex.

2. Build the bsp source code.
3. Copy the bootloader file SD/bpi-m2m/100MB/BPI-M2M-LCD7-8k.img.gz to udisk. bpi also provide a prebuild bootloader for this requirement.
4. Bootup the m2m board from emmc, plugin the udisk and mount it.
5. Flash the bootloader to emmc
   $ sudo bpi-bootsel BPI-M2M-LCD7-8k.img.gz /dev/mmcblk0
or
   $ sudo gunzip -c BPI-M2M-LCD7-8k.img.gz | dd of=/dev/mmcblk0 bs=1024 seek=8
   $ sync
   $ sudo umount /dev/sda1
6. Mout boot partition and set kernel debug console in uEnv.txt
   $ sudo mount -t vfat /dev/mmcblk0p1 /mnt
Change "console=ttyS2,115200" to "console=ttyS0,115200" in /mnt/bananapi/bpi-m2m/linux/lcd7/uEnv.txt
   $ sudo umount /dev/mmcblk0p1
7. Safely poweroff the board and connect debug uart to uart0 three pin header.
