Introduction

The media software development kit from HiSilicon (Shanghai) can adapt to complex underlying layers of different chips. It also provides basic multimedia processing functions for the multimedia subsystem, including audio/video collection, audio/video encoding and decoding, audio/video output, video pre-processing, encapsulation, decapsulation, file management, storage management, and log system. The multimedia subsystem architecture is shown as Figure 1

Constraints

Currently, the Hi3516D V300 chip is supported.

Compilation and Building

• Compiling U-Boot

1. Download the GCC toolchain from https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads. Currently, the toolchain version for compiling U-Boot is gcc-arm-none-eabi-7-2017-q4-major-linux.tar.bz2. You can also select other GCC versions.
2. Copy the GCC toolchain to the prebuilts directory and decompress it.
3. Go to the hispark_taurus\uboot\out\boot directory and modify the path of the toolchain defined by OSDRV_CROSS in the makefile of the directory.
4. Run the make clean;make all; command to compile the U-Boot.

The generated U-Boot is stored in the hispark_taurus\uboot\out\boot directory.
