# reTerminal DM4 eMMC auto-provisioning
Automatically flash a **golden image** to the CM4 eMMC when the reTerminal is connected in **boot mode** (eMMC disable jumper). Optional **backup** mode saves the current eMMC to a timestamped image file instead. Uses **cloud-init** for first-boot configuration.
| File | Purpose |
|------|--------|
| **EMMC-PROVISIONING-GUIDE.md** | Full setup and usage guide – read this first. |
| **flash-emmc-on-connect.sh** | Script that runs `rpiboot` then either flashes the golden image to eMMC or backs up eMMC to a file (mode set via dashboard or `mode` file). |
| **cm4-flash-trigger.sh** | Called by udev when CM4 in boot mode is connected; starts the flash job. |
| **90-cm4-boot-mode.rules** | udev rule: when USB device 2b8e is added, run the trigger script. |
| **cloud-init/** | Example NoCloud files (`user-data`, `meta-data`, `network-config`) for the golden image. |
| **dashboard/** | Flask web UI: auto-detect device (USB or network), prompt **Backup or Deploy**, show status and connection steps. See **dashboard/README.md**. |
| **network-client/** | Script for network-booted devices: register with the dashboard and perform Deploy (pull image, write eMMC) or Backup (upload eMMC). See **network-client/README.md**. |
Quick start: see **EMMC-PROVISIONING-GUIDE.md**.
**Proxmox:** LXC 201 + host setup is documented in **PROXMOX-LXC-DEPLOYMENT.md**. Use **scripts/deploy-to-proxmox.sh** to deploy to a Proxmox host; flash runs on the host, golden image is in a bind-mounted dir shared with the LXC.
