Introduction

Amlogic S905X3 Processor

Banana Pi M5 is a new generation single board computer design , use Amlogic S905X3 Quad-Core Cortex-A55 (2.0xxGHz) Processor. Mali-G31 MP2 GPU with 4 x Execution Engines (650Mhz). support 4GB LPDDR4 and 16G eMMC flash. it have 4 USB 3.0 port,1GbE LAN port.

development

Prepare

1. Prepare a usb-serial cable, a 5V/2A adaptor with type-c power supply. The serial cable is used for console debug and type-c cable is used for android image download and ADB debug.
2. Prepare a SDcard at least 8GB for linux development, android only support emmc boot.
3. The SOC rom first boot media is emmc, so board can't bootup from SDcard if the emmc is bootable with any image flashed, more info please refer to board boot sequence.
4. In Android SDcard is mmc0, emmc is mmc1, but in Linux SDcard is mmc1, emmc is mmc0.

Android

Prepare

1. Download and install the AML Usb Burning Tool for android image download via type-c, only support windows.
2. Download the latest android image.

Install Image with Usb Burning Tool

1. Open USB_Burning_Tool.exe, select menu File->Import image, choose the android image file aml_upgrade_package.img.
M5 android install 1.png


2. M5 board disconnect power, press and hold SW4 button beside 40pin header, plugin type-c usb cable to PC
M5 android install 2.png


3. Click the Start button and wait for upgrade complete.
M5 android install 3.png


4. After Burning successfull, Unplug the type-c usb and connect to power supply adaptor to startup.
M5 android install 4.png


5. Click the Stop button to cancel the upgrade process and close the USB Buring Tool.

Build Android Source Code

1. Get Android 9.0 source code
 $ git clone https://github.com/BPI-SINOVOIP/BPI-S905X3-Android9
2. Build the Android 9.0 Source code
Please read the source code README.md

Linux

Prepare

1. Linux image support SDcard or EMMC bootup, but you should read the boot sequence at first.
2. Make sure bootable EMMC is formatted from sector 0 if you want bootup from SDcard, and make sure bootable SDcard is formatted if you want bootup from EMMC(because uboot read bootscript file from mmc:1 first, which is SDcard dev, This is used for quickly SDcard bootup debug or flash image to EMMC while EMMC is bootable).
3. Install bpi-tools on your Linux PC. If you can't access this URL or any other install problem, please go to bpi-tools source repo, download and install 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 Linux latest Linux Image.
5. Default login: pi/bananapi or root/bananapi

Install Image to SDcard

1. Install image with bpi-tools on Linux, plug SDcard to Linux PC and run
 $ sudo bpi-copy xxx-bpi-m5-xxx.img.zip /dev/sdX
2. Install bpi image with Etcher on Windows, Linux and MacOS.
Balena Etcher is an opensource project by Balena, Flash OS images to SDcard and USB drive

Install Image to EMMC

1. Prepare a SDcard with Linux image flashed and bootup board with this SDcard.
2. Copy Linux image to udisk, plug the udisk to board and mount it.
3. Install with bpi-tools command
 $ sudo bpi-copy xxx-bpi-m5-xxx.img.zip /dev/mmcblk0
4. Install with dd command, umount mmcblk0p1 and mmcblk0p2 partition if mounted automatically.
 $ sudo apt-get install pv
 $ sudo unzip -p xxx-bpi-m5-xxx.img.zip | pv | dd of=/dev/mmcblk1 bs=10M status=noxfer
5. After download complete, power off safely and eject the SDcard.

Build Linux Source Code

1. Get the Linux bsp source code
 $  git clone https://github.com/BPI-SINOVOIP/BPI-M5-bsp
2. Build the bsp source code
Please read the source code README.md
3. If you want build uboot and kernel separately, please download the u-boot the kernel only, get the toolchains and configuration from BPI-M5-bsp

DTB overlay

1. DTB overlay is used for 40pin gpios multi-function configuration and install in vfat BPI-BOOT/overlays
 root@bananapi:~# ls /media/pi/BPI-BOOT/overlays/
 custom_ir.dtbo      pwm_b-backlight.dtbo  spi0.dtbo
 ds3231.dtbo         pwm_c-beeper.dtbo     uart1_cts_rts.dtbo
 hifi_pcm5102a.dtbo  pwm_cd-c.dtbo         uart1.dtbo
 hifi_pcm5122.dtbo   pwm_cd.dtbo           uart2.dtbo
 i2c0.dtbo           pwm_ef.dtbo           waveshare_tft24_lcd.dtbo
 i2c1.dtbo           pwm_ef-f.dtbo         waveshare_tft35c_lcd.dtbo
 pwm_ab.dtbo         sdio.dtbo             waveshare_tft35c_rtp.dtbo
2. Update the overlays env in vfat BPI-BOOT/boot.ini to enable what you want. Default i2c0, spi0 and uart1 enabled.
 # Overlays to load
 # Example combinations:
 #   spi0 i2c0 i2c1 uart0
 #   hktft32
 #   hktft35
 setenv overlays "i2c0 spi0 uart1"
3. Must be restart the board for overlay dtb loaded.

WiringPi

Note: This WiringPi only support set 40pin gpio to output, input or software pwm, for io functions as i2c, spi, pwm..., you must enable dtb overlay in boot.ini
1. Build and install wiringPi
 $ git clone https://github.com/BPI-SINOVOIP/amlogic-wiringPi
 $ cd amlogic-wiringPi
 $ chmod a+x build
 $ sudo ./build
2. Run gpio readall to show all 40pins status.

Erase EMMC for SDcard Bootup

1. Bootable EMMC with Android image flashed
a). Using usb burning tool, unplug the type-c usb cable while the download process at 7% formatting
M5 android format.png
b). Using Android Fastboot tool, make sure the adb/fastboot tools is work on your PC before doing this.
   root@dangku-desktop:/tmp# adb root
   adbd is already running as root
   root@dangku-desktop:/tmp# adb remount
   remount succeeded
   root@dangku-desktop:/tmp# adb shell
   bananapi_m5:/ # reboot fastboot
Wait a few seconds for board reboot to fastboot mode

   erasing 'bootloader-boot1'...
   OKAY [  0.035s]
   finished. total time: 0.035s
c). Using uboot command, connect a debug console cable and press ESC while power on to enter uboot command line
   bananapi_m5_v1#amlmmc erase 1
   emmckey_is_protected(): protect
   start = 0,end = 57343
   start = 221184,end = 30535679
   Erasing blocks 0 to 8192 @ boot0
   start = 0,end = 8191
   Erasing blocks 0 to 8192 @ boot1
   start = 0,end = 8191
   bananapi_m5_v1#reset
   resetting ...

These two ways actually erase the bootloader part of EMMC android, After bootup from SDcard Linux, You'd better format the whole EMMC by dd command.
d). Using uboot reboot command to restart from SDcard once time, Android in EMMC still exist completely, connect a debug console cable and press ESC while power on to enter uboot command line. After bootup from SDcard Linux, you can format the whole EMMC by dd command or flash the Linux image directly to EMMC.
   bananapi_m5_v1#
Insert the SDcard with Linux image flashed now.
   bananapi_m5_v1#reboot sdboot
   reboot mode: sdboot
   reboot dev: sd
   BPI: set rom boot from sdcard after reset
   before value = 0!
   after value = 4f5244c0!

   Load FIP HDR DDR from SD, src: 0x00010200, des: 0xfffd0000, size: 0x00004000, part: 0
   ...
e). The simplest way is insert the SDcard with Linux image flashed before power on, the Android bootloader will check boot.ini file whether exist in SDcard vfat partition, so that the SDcard Linux will bootup. After bootup, you can format the whole EMMC by dd command or flash the Linux image directly to EMMC.
   ...
   BPI: try boot from sdcard

   516 bytes read in 6 ms (84 KiB/s)
   reading overlays/uart1.dtbo
   225 bytes read in 5 ms (43.9 KiB/s)
2. Bootable EMMC with Linux image flashed
a). Using uboot command, connect a debug console cable and press ESC while power on to enter uboot command line
   bananapi_m5# mmc erase 0 1000
b). Linux u-boot also check boot.ini file whether exist in SDcard vfat partition so that the SDcard Linux will bootup. After bootup, you can format the whole EMMC by dd command or flash the Linux image directly to EMMC.
3. Another situation is bootloader or uboot is corrupt, Rom load it from EMMC but hangup in u-boot or BL2, such as dram init failed, the boot process will hangup in BL2 of EMMC. The only way is format the EMMC with usb burning tool, or download the Android image completely and then try other ways to erase EMMC or flash Linux image to EMMC.
