System update (C61)

Upgrade procedure

Prepare upgrade

• Copy vf_hmupdate.img to a USB memory or to /boot/vf_boot.scr on the Linux file system (renaming the file in the latter case only)

If USB method is used

• You can add an autoboot.sh script to the USB memory on the first boot after flash to perform post installation.
• Plug the USB memory into the hardware.
• Press and hold the reset button for 1 sec (all LEDs will blink green if the system has started with the reflash).

If /boot method is used

• Reboot the unit

Wait for upgrade to finish

• Wait 1–2 minutes until finished (until the power LED is green or blink green/orange).
