nearxos 5238d457e8 Update boot order configuration for eMMC first, then network
Modify the first-boot script and documentation to set the EEPROM boot order to 0xf21, prioritizing eMMC boot followed by network boot. Adjust network boot settings for faster failure on DHCP timeouts and update related scripts and documentation to reflect these changes. Enhance the rescue script to directly modify EEPROM settings without requiring a chroot into eMMC, streamlining the recovery process for devices stuck in network-only boot. Update relevant documentation to ensure clarity on the new boot order and its implications.

reTerminal DM4 eMMC provisioning

Automatically deploy or backup the CM4 eMMC when the reTerminal is connected in USB boot mode or when it boots over the network. Uses cloud-init for first-boot configuration.

Quick start

  1. Read docs/EMMC-PROVISIONING-GUIDE.md for setup and usage.
  2. Proxmox: Use scripts/deploy-to-proxmox.sh to deploy to a Proxmox host; see docs/PROXMOX-LXC-DEPLOYMENT.md.
  3. Manual host: Copy scripts from host/ to the host and install the udev rule (see the guide).
  4. Put golden.img in /var/lib/cm4-provisioning/ (or your configured path). When a device is detected (USB or network), the dashboard asks Backup or Deploy.
