Build AOSP on ubuntu20.04 over ASUS Laptop<\/h1>\n

0. Prepare Ubuntu20.04 on laptop<\/h2>\n

Although Ubuntu 22.04 is better fitting in ASUS N7601 (2022) laptop, the building processes of AOSP on RISC-V are not suitable over it. I downgrade my Ubuntu to 20.04 for the building processes, and make a note here…<\/p>\n

0.0. Prevent Ubuntu Black-screen on ASUS Laptop<\/h3>\n
    \n
  1. \n

    Boot up from USB dongle to install ubuntu 20.04, use ‘Safe Graphic’ Mode to prevent screen blanking….<\/p>\n<\/li>\n

  2. \n

    Select minimal install, without 3rd party driver to speedup and prevent blanking….<\/p>\n<\/li>\n

  3. \n

    After done, ubuntu will bootup with safe vga driver.<\/p>\n<\/li>\n

  4. \n

    run "Software & Updates<\/strong>" app, choose "Additional Drivers<\/strong>" Tab, then we can select newest NVIDIA driver, but Nouveau driver is more compatible…
    \n\"image-20230822134940759\"<\/p>\n<\/li>\n

  5. \n

    Driver make video blank? Press Ctrl-Alt+F3<\/code> then Ctrl-Alt+F1<\/code> to get GUI back…<\/p>\n<\/li>\n<\/ol>\n

    0.1. Turn on the Sound Card:<\/h3>\n

    \u200b My laptop speakers are connected on \/dev\/snd\/hwC1D0<\/code> soundcard, while the common hwC0D0 is the HDMI audio device. Since the speaker setting not work under Ubuntu 20.04, a little hacking after each boot up is needed. <\/p>\n

    \u200b The sound card registers needs to be set after bootup (for a little seconds, say 10 seconds), thus the crontab tool was used to do such setting. Steps: <\/p>\n

      \n
    1. \n

      install alsa-tools for sound card control:<\/p>\n

      apt install alsa-tools<\/code><\/pre>\n<\/li>\n
    2. \n
      make a executable script with the following commands:<\/p>\n<\/li>\n<\/ol>\n
      echo \"sudo hda-verb \/dev\/snd\/hwC1D0 0x20 0x500 0xf\nsudo hda-verb \/dev\/snd\/hwC1D0 0x20 0x400 0x7774\nsudo hda-verb \/dev\/snd\/hwC1D0 0x20 0x500 0x45\nsudo hda-verb \/dev\/snd\/hwC1D0 0x20 0x400 0x5289\" |sudo tee \/usr\/local\/bin\/audioup\n\nsudo chmod 755 \/usr\/local\/bin\/audioup<\/code><\/pre>\n
        \n
      1. use crontab -e<\/code>  command to edit the cron script, add the line below to schedule the soundcard setting at 8 sec after bootup:<\/li>\n<\/ol>\n
        @reboot sleep 8; \/usr\/local\/bin\/audioup<\/code><\/pre>\n
        Then the audioup script will be execute after each boot up.<\/p>\n
        0.2. Other Settings<\/h3>\n
