Android DTB overlay
- Bananapi M5 DTBO idx value table, default idx value is 0 in release image.
Bananapi M5 DTBO idx value table idx value device tree overlay description 0 android_p_overlay default dtbo, no use 1 wifi_bt_rtl8822cs enable bpi rtl8822cs wifi/bt module 2 i2c2 enable i2c 2 3 i2c3 enable i2c 3 4 sdio enable sdio 5 uart1 enable 2 pins uart 1 6 uart1_cts_rts enable 4 pins uart 1 7 uart2 enable 2 pins uart 2 8 hifi_pcm5122 enable i2s pcm5122 HiFi DAC
- How to apply a new dtbo
- 1. ADB command via sysfs
root@dangku-desktop:/tmp# adb root restarting adbd as root root@dangku-desktop:/tmp# adb remount remount succeeded root@dangku-desktop:/tmp# adb shell bananapi_m5:/ # echo dtbo > /sys/class/unifykeys/name bananapi_m5:/ # echo "1" > /sys/class/unifykeys/write bananapi_m5:/ # reboot
- 2. Uart console command via sysfs
console:/ $ console:/ $ su console:/ # echo dtbo > /sys/class/unifykeys/name [ 115.702781@0] unifykey: name_store() 1302, name dtbo, 4 [ 115.702856@0] unifykey: name_store() 1311 console:/ # console:/ # echo "1" > /sys/class/unifykeys/write [ 129.262659@0] unifykey: write_store() is a string [ 129.262733@0] unifykey: dtbo, 1, 1 [ 129.265312@0] unifykey: amlkey_write 393 [ 129.292347@1] emmc_key_write:149, write ok console:/ # console:/ # reboot
- 3. Settings App(To-Do)
- Check the bootup uart debug message and confirm which dtbo is loaded actually, here "1" means set idx=1 to apply wifi_bt_rtl8822cs dtbo.
load dtb from 0x1000000 ...... Amlogic multi-dtb tool Single dtb detected find 2 dtbos dtbos to be applied: 1 Apply dtbo 1
- Unifykeys is stored in a specific emmc part, "Normal erase" selected in USB_Burning_Tool will not erase this data for next update, you must select "Erase all" if you want the default dtbo idx to be applied after image download.
- Build Android image with a specific DTBO default.
- 1. Default build-in overlays are defined in device/amlogic/bananapi_m5/Kernel.mk, you can add a new overlay dtbo here.
DTBO_DEVICETREE := android_p_overlay wifi_bt_rtl8822cs i2c2 i2c3 sdio uart1 uart1_cts_rts uart2 hifi_pcm5122
- 2. Default apply DTBO idx is defined in device/amlogic/bananapi_m5/BoardConfig.mk, you can change the idx value to set which overlay dtbo will be applied default.
BOARD_KERNEL_CMDLINE += androidboot.dtbo_idx=0
- 3. DTS files are in common/arch/arm/boot/dts/amlogic/overlay/bananapi_m5/
- More info about android device tree overlays, please refer to google android offical site

Erase EMMC for SDcard Bootup
- There are four possible scenarios should be pay attention to, EMMC already flashed Android image, EMMC already flashed Linux image, boot process hangup in BL2 and EMMC empty.
- 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.
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

- 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, but Android in EMMC still exist completely. Connect a debug console cable and press ESC while power on to enter uboot command line, type "reboot sdboot" command, After reboot from SDcard Linux, you can format the whole EMMC by dd command and then flash the Linux image 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! 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 and then flash the Linux image 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. A extreme situation is bootloader or uboot corrupted, Rom load it from EMMC but hangup in u-boot or BL2, for example the boot process will hangup in BL2 of EMMC if dram init failed, 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.
- 4. Rom will try to load bootloader from SDcard directly if EMMC is empty.
Erase Emmc Android by dd command
- If the board is flashed android before, the whole emmc must be erased by these commands if you want bootup it with SDcard Linux image.
$ sudo dd if=/dev/zero of=/dev/mmcblk0boot0 bs=1M status=noxfer $ sudo dd if=/dev/zero of=/dev/mmcblk0boot1 bs=1M status=noxfer $ sudo dd if=/dev/zero of=/dev/mmcblk0 bs=1M status=noxfer $ sync
