1. Building UEFI
 export BUILD_PATH=~/build
 cd ${BUILD_PATH}
download tools-images-hikey960
 git clone https://github.com/96boards-hikey/tools-images-hikey960
 cd tools-images-hikey960

see README-flash-uefi.md to install ser2net first.
參考 recovery-flash-uefi-prebuilt.sh 分成三步驟
(1) download prebuild from 
https://snapshots.linaro.org/reference-platform/components/uefi-staging/${VERSION}/hikey960/${RELEASE}/

BASE_URL=https://snapshots.linaro.org/reference-platform/components/uefi-staging
VERSION=latest
PRODUCT=hikey960
RELEASE=release
DEVICE=/dev/ttyUSB1
UEFI_URL=${BASE_URL}/${VERSION}/${PRODUCT}/${RELEASE}/
 mkdir -p ./uefi
 cd uefi
 wget -A bin,config,efi,hikey_idt,img,txt -m -nd -np "$UEFI_URL"
It will download these files:
 config     hisi-sec_uce_boot.img     l-loader.bin    recovery.bin
 fip.bin    hisi-sec_usb_xloader.img  MD5SUMS.txt     sec_ptable.img
 hikey_idt  hisi-sec_xloader.img      prm_ptable.img


(2) change board to recovery mode
steps:
 1. board power off, DO NOT use USB->UART convertor
 2. board in recovery mode: jumper: on-on-off
 3. plug type-C in OTG.
 4. board power on. In host PC, you will see /dev/ttyUSB0 node. 只有在recover mode才會有USB 變COM.
 5. cd ./uefi 
 6. sudo ./hikey_idt -c config -p /dev/ttyUSB0
{{image:hikey_idt.png}}

(3) change board to fastboot mode
 sudo fastboot flash ptable prm_ptable.img
 sudo fastboot flash xloader hisi-sec_xloader.img (無法寫入)
 sudo fastboot flash fastboot l-loader.bin
 sudo fastboot flash fip fip.bin

Switch to normal mode, power on

xxx2. Download boot and system image
boot - The FAT32 64MB partition containing GRUB (or xen.efi if desired)
system - The rootfs (Ext4) containing the OS and /boot directory for GRUB to search.

try this:(NO HIKEY960)
https://snapshots.linaro.org/reference-platform/embedded/morty/hikey/latest/rpb/


download rootfs from
 rpb-console-image-hikey960-<some number>.rootfs.img.gz (not used)
download uefi boot
boot-0.0+AUTOINC+<some number>hikey960-<some number>.uefi.img 

find these:
boot-0.0+AUTOINC+06e4def583-fb1158a365-r0-hikey-20191111073000-224.uefi.img
rpb-console-image-hikey-20191111073000-224.rootfs.img.gz


2. Building Linux
 export TOOLS=/opt/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin
 export PATH=$PATH:$TOOLS
 git clone https://github.com/96boards-hikey/linux.git
 cd linux
 git checkout origin/hikey960-upstream-rebase
 export CROSS_COMPILE=aarch64-linux-gnu-
 export ARCH=arm64
 make defconfig
check .config,  CONFIG_XEN_DOM0=y CONFIG_XEN=y
 make -j8
 cp -f arch/$ARCH/boot/Image ../Image
 cp -f arch/$ARCH/boot/dts/hisilicon/hi3660-hikey960.dtb ../Image.dtb

3. Building Xen
 git clone git://xenbits.xen.org/xen.git
 cd xen/xen

 export CROSS_COMPILE=aarch64-linux-gnu-
 export ARCH=arm64
 export XEN_TARGET_ARCH=arm64
 make defconfig
 make -j8
 cp xen.efi ../../

4. Extract the wl18xx-fw-4.bin so your WiFi will work
 git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
 cd linux-firmware
 cp ti-connectivity/wl18xx-fw-4.bin ../

5.下載 rootfs
check https://releases.linaro.org/debian/images/developer-arm64/latest/

 wget https://releases.linaro.org/debian/images/developer-arm64/latest/linaro-stretch-developer- 20170720-71.tar.gz
 sudo tar -xzf linaro-stretch-developer-20180416-89.tar.gz
 sudo mv binary rootfs
 sudo cp Image rootfs/boot
 sudo cp Image.dtb rootfs/boot
 sudo cp xen.efi rootfs/boot
 sudo mkdir -p rootfs/lib/firmware/ti-connectivity
 sudo cp wl18xx-fw-4.bin rootfs/lib/firmware/ti-connectivity

6. Building GRUB
Pre-requirement:
 sudo apt-get install autoconf automake libtool autopoint
6.1 Make 
 git clone  https://git.savannah.gnu.org/git/grub.git
 cd grub
 ./bootstrap => autoconf->autogen.sh=>configure
 export CROSS_COMPILE=aarch64-linux-gnu-
 export ARCH=arm64
 ./configure --prefix=/usr --target=aarch64-linux-gnu --with-platform=efi
 ## --target=target-type the type of system for which any compiler tools in the package produce code
 ## --host=host-type     the type of system on which the package runs.包grub image 的機器. X86
 ## --prefix
 ## --with-platform 
 make
 mkdir ../grub-install
 make DESTDIR=`pwd`/../grub-install install
 cd ../

6.2 create grub.config
copied from rootfs/usr/share/96boards-tools/grub/grub.configfile
 search.fs_label rootfs root
 set prefix=($root)/boot/grub
 configfile $prefix/grub.cfg

 
6.3 create grubaa64.efi
 export GRUB_MODULES="boot chain configfile echo efinet eval ext2 fat font gettext gfxterm gzio help linux loadenv lsefi normal part_gpt part_msdos read regexp search search_fs_file search_fs_uuid search_label terminal terminfo test tftp time xen_boot"
 grub-install/usr/bin/grub-mkimage 
               --config grub.config \
               --dtb Image.dtb \
               --directory=`pwd`/grub-install/usr/lib/grub/arm64-efi \ ##correct: change lib64 to lib
               --output=grubaa64.efi \
               --format=arm64-efi \
               --prefix="/boot/grub" \
               $GRUB_MODULES
Note:



7 create file system image
 mkdir loop
 dd if=/dev/zero of=rootfs.img bs=1M count=2096
 mkfs.ext4 -F -L rootfs rootfs.img #kernel use the label rootfs to mount the rootfs as /
 sudo mount -o loop rootfs.img loop
 cd rootfs
 sudo tar -cf - * | (cd ../loop;sudo tar -xf - )
 cd .. ##change dir to build/
 sudo umount loop
 img2simg rootfs.img rootfs.sparse.img 4096

Note: need install img2simg
 sudo apt install android-tools-fsutils

8. Flash boot.img and system.img
 sudo fastboot flash boot boot-0.0+AUTOINC+06e4def583-fb1158a365-r0-hikey-20191111073000-224.uefi.img
 sudo fastboot flash system rootfs.sparse.img
