Bedrock V3000 does not have a display, so Ubuntu installation requires connecting Bedrock to a host PC using a console (serial over USB).

This document describes Ubuntu installation process on Bedrock V3000.

Test setup

The installation was validated at SolidRun using the following setup:

• Ubuntu versions: Ubuntu server 22.04.1

• Terminal software:

  • Putty

  • Alternatively, Tio can also be used.
    known Tio limitation: in BIOS, the currently selected option is displayed in the same color as the background, which makes it not visible yet it is still fully functional.

• USB flash disk: Kingston Data Traveler

Installation process

Creating bootable USB drive

This step takes place on a host PC running Linux.

• download Ubuntu server .iso file

• Connect a USB thumb drive to your pc

• Run command: 
  lsblk

• Identify your drive (usually /dev/sdX, X can be different for each system) 

  • NOTE: SATA HDDs & SSDs also identify as sdX so be careful not to corrupt your data.

• Run command:
  sudo dd if=${path/to/iso/file.iso} of=/dev/sdX status=progress

• Wait until dd finishes and safely eject the USB drive.

Connecting serial console

Please follow instructions at Using serial console with Bedrock V3000

BIOS settings

You need to enable some configurations in BIOS before starting the installation.

• Remove the quiet parameter and change the entry as follows:
  linux /casper/vmlinuz console=tty1 console=ttyS4,115200n8 systemd.unit=getty@ttyS4.service —

• Wait for the live USB to boot

Live USB settings

After live USB boots run the following services :
sudo systemctl start snapd
sudo systemctl start snapd.socket
sudo systemctl start snapd.seeded
sudo systemctl start snapd.apparmor
sudo systemctl start snapd.core-fixup
sudo systemctl start snapd.autoimport
sudo systemctl start systemd-resolved

  • Add the console redirection:

    • linux /boot/vmlinuz-5.15.0-43-generic root=UUID=4c58e5aa-6443-4fb2-84e7-4ac2265a7b9e ro console=tty1 console=ttyS4,115200n8 recovery nomodeset dis_ucode_ldr
