- 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 sequence is emmc, so board can't bootup from SDcard if the emmc is bootable with any image flashed, more info about the image boot sequence please refer to board boot flow.
- 1. Download and install the AML Usb Burning Tool for android image download via type-c, only support windows.
- 2. Download the AML Burn Card Maker tool for create a bootable sdcard to flash android image to emmc, only support windows.
- 3. 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.
- 2. M5 board disconnect power, press and hold SW4 button beside 40pin header, plugin type-c usb cable to PC
- 3. Click the Start button and wait for upgrade complete.
- 4. After Burning successfull, Unplug the type-c usb and connect to power supply adaptor to startup.
- 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
- 2. Build the Android 9.0 Source code
- Please read the source code README.md
- 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 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
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
- b). Using Android Fastboot tool, make sure the adb/fastboot tools is work on your PC before doing this.
[email protected]:/tmp# adb root adbd is already running as root [email protected]:/tmp# adb remount remount succeeded [email protected]:/tmp# adb shell bananapi_m5:/ # reboot fastboot
- Wait a few seconds for board reboot to fastboot mode

- 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.
- 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! resetting ...

- 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 reading boot.ini 5699 bytes read in 3 ms (1.8 MiB/s) ## Executing script at 01b00000 ... reading Image.gz 9143358 bytes read in 510 ms (17.1 MiB/s) reading meson64_bananapi_m5.dtb 70850 bytes read in 8 ms (8.4 MiB/s) reading uInitrd 11704481 bytes read in 655 ms (17 MiB/s) reading overlays/i2c0.dtbo 223 bytes read in 6 ms (36.1 KiB/s) reading overlays/spi0.dtbo 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. 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.
- 1. DTB overlay is used for 40pin gpios multi-function configuration and install in vfat BPI-BOOT/overlays
[email protected]:~# 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.
- 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.
