EdgeNet appliances

This repository contains the boot scripts for EdgeNet's bare metal nodes.

Odroid N2

N2 boards have three main memories:

• A 8MB flash SPI with petitboot preinstalled
• A eMMC slot
• A SD slot

Our current boot procedure is as follows:

1. petitboot loads the boot/odroid-n2.sh script from GitHub.
2. The script fetch a minimal Ubuntu image and write it to the eMMC.
3. petitboot boots from the eMMC.

This procedure is currently repeated on every boot.

Initial setup

1. Set the MMC/SPI switch at the rear of the board to SPI
2. Plug a keyboard and a screen, or connect via the serial port
3. Plug an Ethernet cable and the power cord
4. Initialize the hardware clock:

# Replace with the actual date and time
date -s "2022-06-08 21:59"
hwclock -w

5. Set the boot script url:

fw_setenv petitboot,userscript https://odroid.edge-net.io/odroid-n2.sh

The provided URL is an alias to https://raw.githubusercontent.com/EdgeNet-project/hardware/main/boot/odroid-n2.sh

6. Update petitboot (we require version 20220317 at-least):

pb-update

7. Verify that the board runs the script
