Build Yukawa userdebug image:
=============================

$ . ./build/envsetup.sh
$ lunch yukawa-userdebug
$ make -j24

- For VIM3L: make TARGET_VIM3L=true -j24

Compile Kernel:
===============

$ git clone https://android.googlesource.com/kernel/hikey-linaro
$ export PATH=$ANDROID_BUILD_TOP/prebuilts/clang/host/linux-x86/clang-r365631c/bin:$PATH

$ cd hikey-linaro
$ git checkout -b android-amlogic-bmeson-4.19 origin/android-amlogic-bmeson-4.19
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- CLANG_TRIPLE=aarch64-linux-gnu- CC=clang meson_defconfig
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- CLANG_TRIPLE=aarch64-linux-gnu- CC=clang -j24
$ lz4c -f arch/arm64/boot/Image arch/arm64/boot/Image.lz4
$ cp arch/arm64/boot/Image.lz4 $ANDROID_BUILD_TOP/device/amlogic/yukawa-kernel
$ cp arch/arm64/boot/dts/amlogic/meson-g12a-sei510.dtb $ANDROID_BUILD_TOP/device/amlogic/yukawa-kernel
$ cp arch/arm64/boot/dts/amlogic/meson-sm1-sei610.dtb $ANDROID_BUILD_TOP/device/amlogic/yukawa-kernel
$ cp arch/arm64/boot/dts/amlogic/meson-sm1-khadas-vim3l.dtb $ANDROID_BUILD_TOP/device/amlogic/yukawa-kernel

$ cd <Path-to-AOSP>; rm out/target/product/yukawa/boot.img out/target/product/yukawa/kernel
$ make bootimage -j24

$ fastboot flash boot out/target/product/yukawa/boot.img

- For VIM3L: make TARGET_VIM3L=true bootimage -j24
- If yukawa-userdebug build was not launched, set direct path to aarch64:
$ export PATH=$ANDROID_BUILD_TOP/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin:$PATH

Recover Bootloader:
===================
Link to 'update' utility: https://github.com/khadas/utils/tree/master/aml-flash-tool/tools/linux-x86

- Enter USB recovery mode by pressing USB Boot Button and turning Power ON
- For VIM3L:
-- Use u-boot_kvim3l_noab.bin rather than u-boot_sei610.bin.
-- Enter recovery / upgrade mode by pressing function button 3 times in 2s.

$ update write u-boot_sei610.bin 0xfffa0000 0x10000
$ update run 0xfffa0000
$ update bl2_boot u-boot_sei610.bin
$ fastboot oem format
$ fastboot flash bootloader u-boot_sei610.bin
$ fastboot erase bootenv
$ fastboot reboot-bootloader
