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 <>`__
- l-loader:
`link <>`__
- u-boot:
`link <>`__
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
- Build l-loader (generated the final fastboot.bin)
1. copy the atf generated files fip.bin and bl1.bin to l-loader/atf/
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.
