Getting OS onto Edge Gateway 3002

Hi

Dunno, Dell play hide and seek with their software.  However there is a long rambling answer from an LLM below....

NB: I did include "headless" as an option, perhaps somewhat unwisely.

Short answer: You can install a standard Linux (Ubuntu Server, Photon OS, or Ubuntu Core) onto the Dell Edge Gateway 3002 and run it headless; Dell provides procedures for creating a recovery/installation USB and for flashing Ubuntu Core/Server images, and community guides describe using a USB-based kickstart/preseed or installing from another machine then moving the storage for fully headless installs.dell+2

Preparation and options

• Supported/known OSes: Dell documents Ubuntu Core and Ubuntu Server for the 3002, and community/VMware guides show Photon OS and similar images have been installed successfully on the 300x family.vmware.github+2

• Headless approaches: use a kickstart/preseed-enabled USB image, create a bootable installer that enables serial/SSH on first boot, or install to the eMMC/SSD on another machine and move the drive into the gateway (or swap drives) to avoid needing a monitor/keyboard during install.reddit+2

Step-by-step (recommended, minimal-interaction / headless)

1. Obtain Dell manual and choose OS image.

   • Download the Edge Gateway 3002 Installation and Operation Manual to follow Dell-specific steps for flashing a new OS and recovery USB creation.dell

   • Pick Ubuntu Server, Ubuntu Core, Photon OS or your preferred distro — Ubuntu Core is officially supported on the 3000 series.canonical+1

2. Prepare a bootable USB installer with automatic install (headless):

   • Create an installer image and add an automated install file: for Debian/Ubuntu use a preseed/cloud-init or autoinstall config; for RHEL/CentOS/Fedora use a kickstart; for Photon OS follow the Photon guide that edits grub.cfg and the sample ks.cfg and includes a UsbInvocationScript if required by the platform.vmware.github+1

   • Ensure console and SSH will be available during installation: add kernel boot params to use serial console (e.g., console=ttyS0,115200n8) and enable/permit root SSH in your postinstall script so you can SSH in as soon as network is up.vmware.github

3. Create the Dell-specific recovery/USB invocation:

   • Dell’s procedure for the 3002 describes creating a recovery USB and (for automated installs) placing the required invocation script or using their flashing steps — follow the manual’s “Flashing a new OS image” and “Creating the recovery USB flash drive” sections.dell+1

4. Boot and discover the device:

   • Insert the USB and power on the gateway; Dell/Photon notes show the installer can run unattended and that once installation finishes you should find the device’s IP from DHCP (MAC is on the unit) and SSH in.dell+1

Alternative headless methods

• Disk swap method: attach the gateway’s eMMC/SSD to another PC, install and preconfigure the OS there (including enabling SSH and network settings), then reinsert the drive in the gateway — this is often the quickest when display/serial is not available.reddit

• PXE + kickstart/preseed: set up a PXE server that supplies an automated install (kickstart/preseed) so the gateway can netboot and install unattended.reddit

Practical tips and pitfalls

• Serial console: many community posts stress using serial console parameters (ttyS0,115200) in installer boot lines so install logs and SSH-enable steps operate headless.vmware.github+1

• Secure Boot/BIOS: check BIOS settings (boot order, secure boot) and firmware methods in Dell manual before attempting to boot from USB.dell

• Network: have DHCP available or preconfigure static network in your automated installer to ensure SSH comes up reachable after install.vmware.github

• Backup: create the Dell recovery USB before making changes so you can restore factory image if needed.dell

Illustrative example (Photon OS automated USB)

• Edit the Photon ISO’s grub.cfg to add kernel parameters: root=/dev/ram0 photon.media=UUID=<photondisk> ks=cdrom:/isolinux/sample_ks.cfg console=ttyS0,115200n8.

• Edit sample_ks.cfg to set target disk to /dev/mmcblk0 (Dell 3002 eMMC) and include postinstall commands to allow SSH root login.

• Copy ISO contents to a FAT32 USB, add a UsbInvocationScript.txt containing the USB boot invocation commands Dell expects, insert USB into Edge Gateway, power on, then find the IP and SSH in when complete.vmware.github

If in doubt please ask.
