Setting Meaning
In
SBC329 boots from Recovery device
Out
SBC329 boots from Main device (default)
In normal operation, a jumper is not fitted on this link, and the SBC329 boots from
the Main device.
The Abaco-programmed Recovery device is for use if the Main device is corrupted.
Booting from the Recovery device puts the SBC329 into Recovery mode. Here, on-
board configuration EEPROMs are disabled, allowing devices to come up using
default strapping.
