Description
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.

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 invoking the arm trusted firmware:
l-loader --> arm_trusted_firmware --> u-boot
How to build
Build Procedure
- Fetch all the above 3 repositories into local host. Make all the repositories in the same ${BUILD_PATH}.
- Prepare the AARCH64 toolchain.
- Build u-boot using poplar_defconfig
- make CROSS_COMPILE=aarch64-linux-gnu- poplar_defconfig make CROSS_COMPILE=aarch64-linux-gnu-
- Build atf providing the previously generated u-boot.bin as the BL33 image
- make CROSS_COMPILE=aarch64-linux-gnu- all fip SPD=none PLAT=poplar BL33=u-boot.bin
- Build l-loader (generated the final fastboot.bin)
- copy the atf generated files fip.bin and bl1.bin to l-loader/atf/
- export ARM_TRUSTED_FIRMWARE=${ATF_SOURCE_PATH)
- 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.
