Xen on Hikey960 Xen on Hikey960 0

Reference: https://wiki.xenproject.org/wiki/HiKey960

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

(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
