/connect — bring up board connectivity

Get the user to a state where ssh root@10.0.0.1 works over ethernet. The board's default IP is 10.0.0.1 on the 10.0.0.0/24 subnet; the host should be 10.0.0.2. Default credentials are root / root.

Steps

1. Probe the board.

   ssh -o ConnectTimeout=3 -o StrictHostKeyChecking=no root@10.0.0.1 'uname -a; cat /etc/os-release'
   

   At the prompt, enter password root. uname -a returns the kernel string and /etc/os-release shows the Hailo SW version (e.g. 1.11.0) — the H15L SBC quickstart §2.3 uses os-release as the canonical version check. Save the IP for the session.

   If it hangs, returns No route to host, or Connection refused, go to step 2.

2. Check ethernet link and host IP.

   • Confirm the cable is plugged into the SBC's RJ45 connector and the host's ethernet port.
   • ip -br addr — the host needs an interface with 10.0.0.2/24. If not, go to step 3.
   • ping -c 2 10.0.0.1 — board reachable?
   • If pingable but ssh refuses, the daemon may not be up yet — wait for boot to finish (green LED on, ~10s after power-on).

3. Set the host's static IP (only if ip -br addr shows no 10.0.0.x interface). Either the GUI or nmcli works — both edit the same NetworkManager connection and persist across reboots.

   CLI:

   # find the wired connection name (usually "Wired connection 1")
   nmcli -t -f NAME,TYPE connection show | grep ethernet
   
   # apply manual IPv4 (replace <name> with the value from above)
   nmcli connection modify "<name>" ipv4.method manual ipv4.addresses 10.0.0.2/24 ipv4.gateway ""
   nmcli connection up "<name>"
   

   GUI: GNOME Settings → Network → Wired (gear icon) → IPv4 → Manual, Address 10.0.0.2, Netmask 255.255.255.0, Gateway empty → Apply.

   Then re-probe.

Gotchas

• The H15L SBC reports as Linux hailo15l … aarch64 from uname -a. The H15H reports hailo15h. Use this to confirm board type.

What success looks like

ssh root@10.0.0.1 'echo OK' returns OK (after entering password root). Report the board IP and uname -a back to the user.
