海鸥派镜像驱动测试

本章主要介绍海鸥派的驱动测试程序。

硬件外设参考 海鸥派硬件特性

海鸥派的驱动测试程序使用说明

  1. 环境准备

    参考 海鸥派镜像构建与使用 准备开发板环境。

  2. 音频测试

    测试前将带麦克风的耳机接入开发板音频输入输出接口。

    export LD_LIBRARY_PATH=/usr/lib
    cd /root/device/sample
    ./audio_sample <index>
    index and its function list below
      0:  start AI to AO loop
      1:  send audio frame to AENC channel from AI, save them
      2:  read audio stream from file, decode and send AO
      3:  read audio stream from Mydream44100.aac file, decode and send AO
      4:  start AI(VQE process), then send to AO
    
  3. HDMI测试

    测试前将显示器和开发板用HDMI2.0线接好。

    export LD_LIBRARY_PATH=/usr/lib
    cd /root/device/sample
    ./audio_hdmi
    hdmi_cmd:
       help                 list all command we provide
       q                    quit sample test
       hdmi_hdmi_force      force to hdmi output
       hdmi_dvi_force       force to enter dvi output mode
       hdmi_deepcolor       set video deepcolor mode
       hdmi_video_timing    set video output timing format
       hdmi_color_mode      set video color output(RGB/ycbcr)
       hdmi_aspectratio     set video aspectratio
       hdmi_a_freq          set audio output frequence
       hdmi_authmode        authmode enable or disable
