Description

HiKey960 is one of 96boards. Hisilicon Hi3660 processor is installed on HiKey960.

How to build

1. Code Locations

ARM Trusted Firmware: link
edk2: link
OpenPlatformPkg: link
l-loader: link
uefi-tools: link

2. Build Procedure

Fetch all the above 5 repositories into local host. Make all the repositories in the same ${BUILD_PATH}.
Create the symbol link to OpenPlatformPkg in edk2.
```
$cd ${BUILD_PATH}/edk2
$ln -sf ../OpenPlatformPkg
```
Prepare AARCH64 toolchain.
If your hikey960 hardware is v1, update uefi-tools/platform.config first. (optional) Uncomment the below sentence. Otherwise, UEFI can't output messages on serial console on hikey960 v1.
```
BUILDFLAGS=-DSERIAL_BASE=0xFDF05000
```
If your hikey960 hardware is v2 or newer, nothing to do.

Build it as debug mode. Create script file for build.

BUILD_OPTION=DEBUG
export AARCH64_TOOLCHAIN=GCC48
export UEFI_TOOLS_DIR=${BUILD_PATH}/uefi-tools
export EDK2_DIR=${BUILD_PATH}/edk2
EDK2_OUTPUT_DIR=${EDK2_DIR}/Build/HiKey960/${BUILD_OPTION}_${AARCH64_TOOLCHAIN}
cd ${EDK2_DIR}
# Build UEFI & ARM Trust Firmware
${UEFI_TOOLS_DIR}/uefi-build.sh -b ${BUILD_OPTION} -a ../arm-trusted-firmware hikey960
# Generate l-loader.bin
cd ${BUILD_PATH}/l-loader
ln -sf ${EDK2_OUTPUT_DIR}/FV/bl1.bin
ln -sf ${EDK2_OUTPUT_DIR}/FV/fip.bin
ln -sf ${EDK2_OUTPUT_DIR}/FV/BL33_AP_UEFI.fd
python gen_loader.py -o l-loader.bin --img_bl1=bl1.bin --img_ns_bl1u=BL33_AP_UEFI.fd

Generate partition table. Make sure that you're using the sgdisk in the l-loader directory.
```
$PTABLE=aosp-32g SECTOR_SIZE=4096 SGDISK=./sgdisk bash -x generate_ptable.sh
```

3. Setup Console

Install ser2net. Use telnet as the console since UEFI will output window that fails to display in minicom.
```
$sudo apt-get install ser2net
```

Configure ser2net.

$sudo vi /etc/ser2net.conf

Append one line for serial-over-USB in #ser2net.conf

2004:telnet:0:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT banner

Open the console.
```
$telnet localhost 2004
```
And you could open the console remotely, too.

4. Boot UEFI in recovery mode

Fetch that are used in recovery mode. The code location is in below. link

Generate l-loader.bin.

$cd tools-images-hikey960
$ln -sf ${BUILD_PATH}/l-loader/l-loader.bin

Prepare config file.

$vi config
# The content of config file
./sec_user_xloader.img 0x00020000
./sec_uce_boot.img 0x6A908000
./l-loader.bin 0x1AC00000

Remove the modemmanager package. This package may causes hikey_idt tool failure.
```
$sudo apt-get purge modemmanager
```
Run the command to download l-loader.bin into HiKey960.
```
$sudo ./hikey_idt -c config -p /dev/ttyUSB1
```
UEFI running in recovery mode. When prompt '.' is displayed on console, press hotkey 'f' in keyboard. Then Android fastboot app is running. The timeout of prompt '.' is 10 seconds.

Update images.

$sudo fastboot flash ptable prm_ptable.img
$sudo fastboot flash xloader sec_xloader.img
$sudo fastboot flash fastboot l-loader.bin
$sudo fastboot flash fip fip.bin
$sudo fastboot flash boot boot.img
$sudo fastboot flash cache cache.img
$sudo fastboot flash system system.img
$sudo fastboot flash userdata userdata.img

Notice: UEFI could also boot kernel in recovery mode, but BL31 isn't loaded in recovery mode.

5. Boot UEFI in normal mode

Make sure "Boot Mode" switch is OFF for normal boot mode. Then power on HiKey960.
