rOS - DIY rAudio

Build rAudio - Audio player and renderer for Raspberry Pi

• For all Raspberry Pis:
  • 64bit:
    • 4, 3 and 2
    • Zero 2 cannot be used to run this DIY. Use pre-built image file instead.
  • 32bit:
    • 2 (BCM2836)
  • Legacy:
    • 1 and Zero : Arch LinuxARM ended ARMv6 CPU support. Use pre-built image file instead.
• Create rAudio from latest releases of Arch Linux ARM
• Interactive interface
• Options:
  • Pre-configure Wi-Fi connection
  • Exclude features (can be as light as possible in terms of build time and disk space)

Procedure

• Download and create Arch Linux ARM
• SSH to Raspberry Pi
• Create rAudio
  • Upgrade kernel and default packages
  • Install feature packages
  • Install web user interface
  • Configure
  • Setup defaults

Need

• PC - Linux or Linux Live USB e.g. , Manjaro (Arch Linux) , Debian , Mint
• Raspberry Pi
• Micro SD card or USB drive

Create rAudio

Target device:

• Option 1: Micro SD card (Should be at least class 10 or U1)
• Option 2: USB drive (Not for Zero and 1)
  • Suitable for much-faster-than-SD-card drives.
  • Normal hard drive needs external power, e.g., powered USB hub, to have it spin up 5+ seconds before boot.
  • USB mass storage boot must be enabled on Raspberry.
  • Boot might takes 10+ seconds longer: Detect no sd card » read boot loader » boot

Note: Device larger than 2TB will be setup as GPT

• For Raspberry Pi 5, 4 and 3B+ only
• Other models: Use the device as storage with rAudio on SD card

Note: Use router pre-assigned IP address for Raspberry Pi if possible.

Run script

• Open terminal on Linux
  • Ubuntu: Drag terminal height to at least 40 lines
  • Others: Resized by script
• Switch to user root

# live usb: set root password (no need for manjaro)
sudo passwd root

su

• Run

bash <( wget -qO- https://raw.githubusercontent.com/rern/rOS/main/create-alarm.sh )

Optionals

Setup Wi-Fi auto-connect for headless/no screen (if not set during build)

• On Linux or Windows
• Insert micro SD card
• 3 alternatives:
  1. From existing
     • Backup the profile file from /etc/netctl/PROFILE
     • Rename it to wifi then copy it to BOOT before power on.
  2. Edit template file - name and password
     • Open wifi0 in BOOT with text editor
     • Edit SSID and Key
     • Save as wifi
  3. Generate a complex profile - static IP, hidden SSID
     • With Pre-configure Wi-Fi connection
     • Save it in BOOT
• Move micro SD card to Raspberry Pi
• Power on

Create image file (BOOT and ROOT on single device only)

• Once started rAudio successfully
• SSH to RPi
• Reset for image

ssh root@<RPI IP>
bash <( curl -sL https://github.com/rern/rOS/raw/main/image-reset.sh )

• Shutdown
• Move micro SD card to Linux
• Create compressed image file

bash <( curl -sL https://github.com/rern/rOS/raw/main/image-create.sh )
