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

Please follow instructions at https://solidrun.atlassian.net/l/cp/m9Reo11r

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.

• Insert the USB media to the device

• Turn on Bedrock

• Repetitively press the DEL / ESC key to enter the BIOS setup

• In BIOS go to -> Save & Exit -> <your bootable USB device> -> yes

• Device will reset and a grub screen will appear

Configure grub

A grub menu will appear saying try or install Ubuntu. Press ‘e’ to set the boot parameters.

• You will be prompted with a window like this:

setparams 'Install Ubuntu Server'
set gfxpayload=keep
linux        /casper/vmlinuz   quiet  --- 
initrd        /casper/initrd

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

• Wait for the live USB to boot
