GX8005/6 Development Environment Setup*

The GX8005/6 chip SDK needs to be compiled in a Linux environment. This article mainly introduces how to set up the SDK development and compilation environment.

Note

For Windows developers, you can use VirtualBox virtual machine software to install Ubuntu, then read the following content to install the required compilation tools, and you can also carry out SDK development.

1. SDK Toolchain Installation*

  • Click the link http://yun.nationalchip.com:10000/l/3FjmDz to download it to the local ~/Downloads/ directory.
  • Extract Xuantie-900-gcc-elf-newlib-x86_64-V2.10.2-20240904.tar.gz to /opt 
    sudo tar zxvf Xuantie-900-gcc-elf-newlib-x86_64-V2.10.2-20240904.tar.gz -C /opt/
  • Then edit ~/.profile or ~/.bashrc, and add /opt/Xuantie-900-gcc-elf-newlib-x86_64-V2.10.2/bin to the PATH variable 
    gedit $HOME/.bashrc
Add at the end
export PATH=$PATH:/opt/Xuantie-900-gcc-elf-newlib-x86_64-V2.10.2/bin
Save and exit
  • Close the terminal and reopen it, so that ~/.profile or ~/.bashrc will take effect.

2. Obtaining the SDK Package*

  • Two project packages need to be pulled: ovp_aiot and viva. They are both hosted on the GtiLab private repository. Please read Register GitLab Account and provide your GitLab account to our sales manager, who will have our project manager release the code for that account.

3. Creating the First Demo*

3.1. Compilation*

cp configs/example/opus_play/8005_internal_pa_play.config .config
make defconfig
make

Note

make menuconfig / make defconfig may sometimes encounter this error Linux Error: ncurses.h: No such file or directory. This is due to missing dependent libraries. The Ubuntu solution is: sudo apt-get install libncurses5-dev.

3.2. Firmware Flashing*

cd tools/bootx/
./flash_nor.sh 1 -r 1000000 # The number 1 indicates the serial port number, and the number after -r is the baud rate

3.3. Running*

  • Open your serial terminal, then restart the development board. The following output will appear:
