APPENDIX D: UPDATING FIRMWARE

Updating off-line, without internet access

If the UltraLite AVB (and the computer it is

connected to) has no internet access, you can

download a ﬁrmware update ﬁle from another

computer that does have internet, and then use the

ﬁle to update the UltraLite AVB, as follows:

1 Download the ﬁrmware ﬁle.

2 Transfer the ﬁle to a computer with a network

cable connection to the UltraLite AVB.

3 Launch the MOTU AVB Control web app on the

computer, as usual.

4 Go to the Device tab.

5 Scroll down to the bottom and click Update

from File.

6 Locate the ﬁle on your hard drive and click OK

to start the update.

7 Follow the on-screen instructions.

Viewing the latest ﬁrmware version

information

You can conﬁrm the ﬁrmware version at the

bottom of the Device tab (Figure D-2).

Why does the ﬁrmware update require a

network cable?

Firmware updating was designed to use ethernet

mostly for convenience. If you have lots of

networked devices, you can upgrade them all from

a distance (even over Wi-Fi) without having to plug

in directly and without having to download or run

an updater application.

This approach was also taken for engineering

reasons, with reliability foremost in mind. When

installing an update, the device reboots into a

stripped-down recovery partition to guarantee

that the update process can always be completed,

even if the power goes out mid-update. Since

updates can also affect the Thunderbolt or USB

chips, they cannot be used during the update.

Figure D-2: The currently installed ﬁrmware version is displayed at the bottom of the Device tab.
