7.9. HiKey

HiKey is one of 96boards. Hisilicon Kirin6220 processor is installed on HiKey.

7.9.1. How to build

7.9.1.1. Code Locations

Trusted Firmware-A: link
OP-TEE link
edk2: link
OpenPlatformPkg: link
l-loader: link
atf-fastboot: link

7.9.1.2. Build Procedure

Fetch all the above repositories into local host. Make all the repositories in the same ${BUILD_PATH}.

git clone https://github.com/ARM-software/arm-trusted-firmware -b integration
git clone https://github.com/OP-TEE/optee_os
git clone https://github.com/96boards-hikey/edk2 -b testing/hikey960_v2.5
git clone https://github.com/96boards-hikey/OpenPlatformPkg -b testing/hikey960_v1.3.4
git clone https://github.com/96boards-hikey/l-loader -b testing/hikey960_v1.2
git clone https://github.com/96boards-hikey/atf-fastboot

Create the symbol link to OpenPlatformPkg in edk2.

$cd ${BUILD_PATH}/edk2
$ln -sf ../OpenPlatformPkg

Prepare AARCH64 && AARCH32 toolchain. Prepare python.
If your hikey hardware is built by CircuitCo, update OpenPlatformPkg/Platforms/Hisilicon/HiKey/HiKey.dsc first. (optional) console on hikey.**
```
DEFINE SERIAL_BASE=0xF8015000
```
If your hikey hardware is built by LeMaker, nothing to do.
Build it as debug mode. Create your own build script file or you could refer to build_uefi.sh in l-loader git repository.
```
cd {BUILD_PATH}/arm-trusted-firmware
sh ../l-loader/build_uefi.sh hikey
```

Generate l-loader.bin and partition table for aosp. The eMMC capacity is either 8GB or 4GB. Just change “aosp-8g” to “linux-8g” for debian.

cd ${BUILD_PATH}/l-loader
ln -sf ${EDK2_OUTPUT_DIR}/FV/bl1.bin
ln -sf ${EDK2_OUTPUT_DIR}/FV/bl2.bin
ln -sf ${BUILD_PATH}/atf-fastboot/build/hikey/${FASTBOOT_BUILD_OPTION}/bl1.bin fastboot.bin
make hikey PTABLE_LST=aosp-8g

7.9.2. Setup Console

Install ser2net. Use telnet as the console since UEFI fails to display Boot Manager GUI in minicom. If you don’t need Boot Manager GUI, just ignore this section.
```
$sudo apt-get install ser2net
```

Configure ser2net.

$sudo vi /etc/ser2net.conf

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

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

Start ser2net
```
$sudo killall ser2net
$sudo ser2net -u
```
Open the console.
```
$telnet localhost 2004
```
And you could open the console remotely, too.

7.9.3. Flash images in recovery mode

Make sure Pin3-Pin4 on J15 are connected for recovery mode. Then power on HiKey.
Remove the modemmanager package. This package may cause the idt tool failure.
```
$sudo apt-get purge modemmanager
```

Run the command to download recovery.bin into HiKey.

$sudo python hisi-idt.py -d /dev/ttyUSB1 --img1 recovery.bin

Update images. All aosp or debian images could be fetched from link.

$sudo fastboot flash ptable prm_ptable.img
$sudo fastboot flash loader l-loader.bin
$sudo fastboot flash fastboot 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

7.9.4. Boot UEFI in normal mode

Make sure Pin3-Pin4 on J15 are open for normal boot mode. Then power on HiKey.
