Bedrock V3000 lacks an integrated display adapter. Consequently, to install Ubuntu, users must connect Bedrock to a host PC using a console, facilitated by serial over USB.
This document describes Ubuntu installation process on Bedrock V3000.
This installation process has been validated by SolidRun with the following configurations:
Ubuntu versions:
Ubuntu server 22.04
Ubuntu server 23.04
Terminal software:
Putty
USB flash disk: Kingston Data Traveler
Download the modified installer to a USB drive
Please follow instructions at https://solidrun.atlassian.net/l/cp/m9Reo11r
Installer modifications:
