LAN Turtle firmware may be updated”over the air” by choosing Check for Updates from the Config menu. If an Internet providing Ethernet connection is not available, updates may be flashed to the device manually using the following process:
Download the latest UPDATE file from the download center and verify its checksum.
Verify that the SHA256 checksums match
Manually SCP the file to the LAN Turtle in /tmp (ex: scp turtle-5.bin [email protected]:/tmp/)
From the LAN Turtle, exit shell to the bash prompt and issue: sysupgrade -n /tmp/turtle-3.bin
Wait about 5 minutes for the LAN Turtle to flash the firmware and reboot itself
