Build rAudio - Audio player and renderer for Raspberry Pi

• For all Raspberry Pis: Zero, 1, 2, 3 and 4
• Create rAudio from latest releases of Arch Linux Arm
• Interactive interface
• Options:
  • Run ROOT partition on USB drive
  • Run on USB only - no SD card (boot from USB)
  • Pre-configure Wi-Fi connection (headless mode)
  • Exclude features (can be as light as possible in terms of build time and disk space)
• Take less than 15 minutes for the whole process with a decent download speed.

Procedure

• Prepare partitions
  • Create BOOT and ROOT partitions
• Create Arch Linux Arm + rAudio
  • Use wired LAN connection if possible
    • Use router assigned IP address if possible
      • Router may take some time to broadcast hostname of DHCP Raspberry Pi
    • Optional - Pre-configure Wi-Fi connection
  • Select features
  • Download Arch Linux Arm
  • Write BOOT and ROOT
  • SSH connect PC to Raspberry Pi
  • Upgrade kernel and default packages
  • Install feature packages
  • Install web user interface
  • Configure
  • Set defaults
• Optionals
  • Setup Wi-Fi auto-connect
  • Create image file
• Expert mode (1 command line - micro SD card only)

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

Need

• PC - Linux - any distro
  • or on USB e.g., Manjaro - Arch Linux
  • or on Raspberry Pi itself (If no GUI, fdisk and mount skills needed.)
  • or on VirtualBox on Windows (with network set as Bridge Adapter) - Slowest
• Raspberry Pi
• Network connection to Raspberry Pi
  • Wired LAN
  • Optional: Wi-Fi (if necessary)
• Media:
  • Micro SD card shoule be at least class 10 or U1.
  • Option 1: Micro SD card: 8GB+ for BOOT + ROOT partitions
  • Option 2: Micro SD card + USB drive (ROOT partition on USB drive)
    • Micro SD card: 200MB+ for BOOT partition only
    • USB drive: 8GB+ for ROOT partition (or USB hard drive with existing data)
  • Option 3: USB drive only - no SD card (Boot from USB drive)
    • Raspberry Pi 3 and 2 v1.2 only (4 not yet supported)
    • USB drive: 8GB+ for BOOT + ROOT partition
  • Note for USB drive:
    • Suitable for hard drives or faster-than-SD-card thumb drives.
    • Boot from USB drive:
      • Suitable for solid state drives.
      • Normal hard drive needs external power, e.g., powered USB hub, to have it spin up 5+ seconds before boot.
      • Boot takes 10+ seconds longer (detect no sd card > read boot loader into memory > boot)

• On Linux PC
• Open GParted app (Manjaro root password: manjaro)
• 3 Alternatives:
  • Micro SD card only
  • Micro SD card + USB drive
  • USB drive only

Alternative 1: Micro SD card only

• Unmount > Delete all partitions (make sure it's the micro SD card)
• Create partitions:

Alternative 2: Micro SD card + USB drive

• Micro SD card
  • Unmount > Delete all partitions (Caution: make sure it's the SD card)
  • Create a partition:

• USB drive - Blank:
  • Unmount > Delete all partitions (Caution: make sure it's the USB drive)
  • Create partitions:

• or USB drive - with existing data:
  • No need to reformat or change format of existing partition
  • Resize the existing to get 5000MiB unallocated space (anywhere - at the end, middle or start of the disk)
  • Create a partition in the space:

Alternative 3: USB drive only

• Enable boot from USB: Set boot bit (Micro SD card can still be used as usual if inserted.)
• Create partitions: (Drive with existing data must be resized and rearranged respectively.)

• Open Files app (File Manager on Manjaro)
• Click BOOT and ROOT to mount
• Note each path in location bar or hover mouse over BOOT and ROOT for confirmation
• Switch user to root

su

-if Manjaro, update package mirror list

pacman-mirrors -c COUNRTY

• Create script

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

• Errors or too slow download: press Ctrl+C and run ./create-alarm.sh again (while in Create Arch Linux Arm mode only)

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 (Micro SD card mode only)

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

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

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

bash <( wget -qO - https://github.com/rern/rOS/raw/main/imagecreate.sh )

Fix - Error: Known host keys on SSH

sed -i "/IP_ADDRESS/ d" ~/.ssh/known_hosts
