HiKey
=====
HiKey is one of 96boards. Hisilicon Kirin6220 processor is installed on HiKey.
More information are listed in `link`_.
How to build
------------
Code Locations
~~~~~~~~~~~~~~
- Trusted Firmware-A:
`link <https://github.com/ARM-software/arm-trusted-firmware>`__
- OP-TEE
`link <https://github.com/OP-TEE/optee_os>`__
- edk2:
`link <https://github.com/96boards-hikey/edk2/tree/testing/hikey960_v2.5>`__
- OpenPlatformPkg:
`link <https://github.com/96boards-hikey/OpenPlatformPkg/tree/testing/hikey960_v1.3.4>`__
- l-loader:
`link <https://github.com/96boards-hikey/l-loader/tree/testing/hikey960_v1.2>`__
- uefi-tools:
`link <https://git.linaro.org/uefi/uefi-tools.git>`__
- atf-fastboot:
`link <https://github.com/96boards-hikey/atf-fastboot/tree/master>`__
Build Procedure
~~~~~~~~~~~~~~~
- Fetch all the above repositories into local host.
Make all the repositories in the same ${BUILD\_PATH}.
.. code:: shell
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://git.linaro.org/uefi/uefi-tools
git clone https://github.com/96boards-hikey/atf-fastboot
- Create the symbol link to OpenPlatformPkg in edk2.
.. code:: shell
$cd ${BUILD_PATH}/edk2
$ln -sf ../OpenPlatformPkg
- Prepare AARCH64 && AARCH32 toolchain. Prepare python.
- If your hikey hardware is built by CircuitCo, update *uefi-tools/platform.config* first. *(optional)*
**Uncomment the below sentence. Otherwise, UEFI can't output messages on serial
console on hikey.**
.. code:: shell
BUILDFLAGS=-DSERIAL_BASE=0xF8015000
If your hikey hardware is built by LeMaker, nothing to do.
- Build it as debug mode. Create your own build script file or you could refer to **build\_uefi.sh** in l-loader git repository.
.. code:: shell
BUILD_OPTION=DEBUG
export AARCH64_TOOLCHAIN=GCC5
export UEFI_TOOLS_DIR=${BUILD_PATH}/uefi-tools
export EDK2_DIR=${BUILD_PATH}/edk2
EDK2_OUTPUT_DIR=${EDK2_DIR}/Build/HiKey/${BUILD_OPTION}_${AARCH64_TOOLCHAIN}
# Build fastboot for Trusted Firmware-A. It's used for recovery mode.
cd ${BUILD_PATH}/atf-fastboot
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=hikey DEBUG=1
# Convert DEBUG/RELEASE to debug/release
FASTBOOT_BUILD_OPTION=$(echo ${BUILD_OPTION} | tr '[A-Z]' '[a-z]')
cd ${EDK2_DIR}
# Build UEFI & Trusted Firmware-A
${UEFI_TOOLS_DIR}/uefi-build.sh -b ${BUILD_OPTION} -a ../arm-trusted-firmware -s ../optee_os 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.
.. code:: shell
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
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.**
.. code:: shell
$sudo apt-get install ser2net
- Configure ser2net.
.. code:: shell
$sudo vi /etc/ser2net.conf
Append one line for serial-over-USB in below.
*#ser2net.conf*
.. code:: shell
2004:telnet:0:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT banner
- Start ser2net
.. code:: shell
$sudo killall ser2net
$sudo ser2net -u
- Open the console.
.. code:: shell
$telnet localhost 2004
And you could open the console remotely, too.
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.
.. code:: shell
$sudo apt-get purge modemmanager
- Run the command to download recovery.bin into HiKey.
.. code:: shell
$sudo python hisi-idt.py -d /dev/ttyUSB1 --img1 recovery.bin
- Update images. All aosp or debian images could be fetched from `link <http://releases.linaro.org/96boards/>`__.
.. code:: shell
$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
Boot UEFI in normal mode
------------------------
- Make sure Pin3-Pin4 on J15 are open for normal boot mode. Then power on HiKey.
- Reference `link <https://github.com/96boards-hikey/tools-images-hikey960/blob/master/build-from-source/README-ATF-UEFI-build-from-source.md>`__
