Hello All,

I am trying to build AOSP with Android 14 and Kernel version 6.1 on Khadas VIM3 board.

As a starting step I flashed the prebuilt images from https://dl.khadas.com/products/vim3/firmware/android/vim3-tablet-aosp-main-20241220.tar.gz and worked.

Next step I only build the AOSP code and flashed the images. This step did not work.

More details are as below,

  1. Obtaining the AOSP code

    mkdir khadas-aosp-14 && cd $_

    repo init -u https://android.googlesource.com/platform/manifest -b main

    repo sync

  2. Compiling the code

  3. export TARGET_VIM3=true

    export TARGET_AVB_ENABLE=true

    export TARGET_KERNEL_USE=6.1

    export TARGET_USE_TABLET_LAUNCHER=true

    ./device/amlogic/yukawa/fetch-vendor-package.sh

    source build/envsetup.sh && lunch yukawa-trunk_staging-userdebug

    time make -j50 2>&1 | tee build_vim3_14_android.log

  4. Flash the images

    1. Images and location
    2. Image Location Remark Column 4
      u-boot_kvim3_ab.bin out/target/product/yukawa
      and vendor/amlogic/yukawa/bootloader/20241217 Both images are having same size. So, I assume it is copied from bootloader/20241217 to product/yukawa
      boot.img out/target/product/yukawa
      super.img out/target/product/yukawa
      userdata.img out/target/product/yukawa
      dtbo-unsigned.img out/target/product/yukawa

$ pip3 install pyamlboot

Bootloader

$ export BOOTLOADER_NAME=u-boot_kvim3_ab.bin

$ cd vendor/amlogic/yukawa/bootloader/20241217

$ boot-g12.py ${BOOTLOADER_NAME}

$ fastboot flash bootloader ${BOOTLOADER_NAME}

$ fastboot erase bootenv && fastboot oem format && fastboot reboot bootloader

Press the R button

    1. Load the Android images

$ cd out/target/product/yukawa

$ fastboot flash boot_a boot.img && fastboot flash boot_b boot.img && fastboot flash super super.img && fastboot flash userdata userdata.img && fastboot flash dtbo_a dtbo-unsigned.img && fastboot flash dtbo_b dtbo-unsigned.img && fastboot erase misc && fastboot erase frp && fastboot format metadata && fastboot reboot

Post the rebooting of the board, still get an error of Failed to boot Android!
