DIY Image file

• rOS - Build image files with interactive process

How-to

• Write an image file to a micro SD card (8GB or more):
  • Install Raspberry Pi Imager
    • Windows, MacOS, Ubuntu: Raspberry Pi Imager
    • Manjaro: pacman -Sy rpi-imager
    • Others: Build and install
  • Download an image file.
  • CHOOSE OS > Use custom (OR right click the image file > Open with > Raspberry Pi Imager)
  • CHOOSE STORAGE > select SD card > WRITE
  • Verify is optional.
  • Boot from USB drive without SD card
    • For Raspberry Pi 2B v1.2, 3A+, 3B, 3B+, 4B
    • Setup USB mass storage boot
    • CHOOSE STORAGE > select USB drive > WRITE
    • Should be used only when USB drive is faster than SD card.
• Existing users:
  • Keep current setup SD card.
  • Try with a spare one before moving forward.
  • Always use backup.gz created by latest update to restore system.
• Before power on:
  • Wi-Fi pre-configure - 4 alternatives: (Only if no wired LAN available.)
    • From backup.gz
    • From existing
      • Copy an existing profile file from /etc/netctl
      • Rename it to wifi then copy it to BOOT before power on.
    • Edit template file - name and password.
      • Rename wifi0 in BOOT to wifi
      • Edit SSID and Key.
    • Generate a complex profile - static IP, hidden SSID
      • With Pre-configure Wi-Fi connection
      • Save it in BOOT
  • Wi-Fi access point mode
    • If no wired network and no pre-configured Wi-Fi connections, Wi-Fi access point will be enabled on boot.
    • On client devices, select rAudio from Wi-Fi network list to connect.
    • On browser, open web user interface with URL raudio.local
    • Settings > Networks > Wi-Fi - search
    • Select access point to connect
    • Reboot
    • Browser refreshes when ready. (Manually refresh if it's too long.)
  • System pre-configure: (Run once)
    • Restore database and settings (Wi-Fi connection included.)
      • Copy backup.gz to BOOT
    • Expand root partition:
      • By default, root partition will be expaned on initial boot.
      • SD card backup with shrunken root partition - Create a blank file expand in BOOT before backup
    • GPIO 3.5" LCD display (Not for Zero and 1)
      • Create a blank file lcd in BOOT
    • Custom startup script
      • Copy custom script named startup to BOOT
• Boot duration
  • RPi4: 20+ seconds
  • RPi3: 50+ seconds
  • RPi1, Zero: 80+ seconds
• After initial boot:
  • If connected to a screen, IP address and QR code for connecting from remote devices displayed.
  • Before setup anything: Settings > Addons > rAudio > Update (if available)
  • Restore settings and database:
    • If not pre-configured, Settings > System > Backup/Restore Settings
  • Update Library database:
    • Automatically run on boot if database is empty with connected USB and NAS
    • Force update - Settings > update Library (icon next to Sources)
  • Parse coverarts for Album and directory thumbnails :
    • Only if never run before or to force update
    • Library > Album > coverart icon (next to ALBUM heading)
  • User guide
    • Settings > last icon next to Addons
• User's startup / shutdown scripts
  • /boot/startup.sh - Run after everyting started.
  • /boot/shutdown.sh - Run last right before shutdown command.

Not working?

• Power off and wait a few seconds then power on
• If not connected, temporarily connect wired LAN then remove after Wi-Fi setup successfully.
• Still no - Download the image file and start over again

Tips

• Best sound quality:
  • Settings > MPD > Bit-perfect - Enable
  • Use only amplifier volume (Unless quality of DAC hardware volume is better.)
• Disable features if not use to lower CPU usage: Settings > System > Features
• Coverart as large playback control buttons
  • Tap top of coverart to see controls guide.
• Hide top and bottom bars
  • No needs for top and bottom bars
  • Use coverart controls instead of top bar buttons
  • Swipe to switch between pages <- Library <-> Playback <-> Playlist ->
• Drag to arrange order
  • Library home blocks
  • Playlist tracks
  • Saved playlist tracks
• Some coverarts missing from album directories
  • Subdirectories listed after partial Library database update from context menu.
  • Subdirectories - context menu > Exclude directory
• Some music files missing from library
  • Settings > MPD > question mark icon -scroll- FFmpeg Decoder
  • Enable if filetypes list contains ones of the missing files.
• No albums found after update very large Library
  • Settings > MPD > Output Buffer - Increase by 8192 at a time
  • Update Library
• CUE sheet
  • *.cue filenames must be identical to each coresponding music file.
  • Can be directly edited by Tag Editor.
• Minimum permission for music files (on Linux ext filesystem)
  • Directories: rwxr-xr-x (755)
  • Files: rw-r--r-- (644)
• RPi to router connection:
  • With wired LAN if possible - Disable Wi-Fi
  • With WiFi if necessary
  • With RPi accesspoint only if there's no router
• Connect to rAudio with IP address instead of raudio.local
  • Get IP address: Menu > Network > Network Interfaces list
• Backup SD card which already setup
  • On Linux: bash <( wget -qO - https://github.com/rern/rOS/raw/main/imagecreate.sh )
    • Shrink ROOT partition to minimum
    • Create and compress image file
• App icon (Full screen UI) - Add to Home Screen
  • Android Chrome / iOS Safari
