Poplar
======
Poplar is the first development board compliant with the 96Boards Enterprise
Edition TV Platform specification.
The board features the Hi3798C V200 with an integrated quad-core 64-bit
Arm Cortex A53 processor and high performance Mali T720 GPU, making it capable
of running any commercial set-top solution based on Linux or Android.
It supports a premium user experience with up to H.265 HEVC decoding of 4K
video at 60 frames per second.
::

CONNECTORS One connector for Smart Card One connector for TSI
At the start of the boot sequence, the bootROM executes the so called l-loader
binary whose main role is to change the processor state to 64bit mode. This
must happen prior to invoking Trusted Firmware-A:
::
l-loader --> Trusted Firmware-A --> u-boot
How to build
------------
Code Locations
~~~~~~~~~~~~~~
- Trusted Firmware-A:
`link <https://github.com/ARM-software/arm-trusted-firmware>`__
- l-loader:
`link <https://github.com/Linaro/poplar-l-loader.git>`__
- u-boot:
`link <http://git.denx.de/u-boot.git>`__
Build Procedure
~~~~~~~~~~~~~~~
- Fetch all the above 3 repositories into local host.
Make all the repositories in the same ${BUILD\_PATH}.
- Prepare the AARCH64 toolchain.
- Build u-boot using poplar_defconfig
.. code:: bash
make CROSS_COMPILE=aarch64-linux-gnu- poplar_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-
- Build atf providing the previously generated u-boot.bin as the BL33 image
.. code:: bash
make CROSS_COMPILE=aarch64-linux-gnu- all fip SPD=none PLAT=poplar
BL33=u-boot.bin
- Build l-loader (generated the final fastboot.bin)
1. copy the atf generated files fip.bin and bl1.bin to l-loader/atf/
2. export ARM_TRUSTED_FIRMWARE=${ATF_SOURCE_PATH)
3. make
Install Procedure
-----------------
- Copy l-loader/fastboot.bin to a FAT partition on a USB pen drive.
- Plug the USB pen drive to any of the USB2 ports
- Power the board while keeping S3 pressed (usb_boot)
The system will boot into a u-boot shell which you can then use to write the
working firmware to eMMC.
