LED Descriptions 73
7.1 User LEDs (Green)
7.2 BIT Status LEDs (Red)
7.3 Ethernet LEDs (Yellow)
These
LEDs
are
under
the
control
of
the
88E1111
PHYs
and
the
descriptions
define
the
default
functions
of
the
LED
outputs.
These
are
under
software
control,
however,
and
may
be
subsequently
reassigned
if
required.

BIT Fail core 0
BIT Fail core 1
Once a board has been programmed with firmware,
these LEDS are lit red at power up. Software is used to
switch them off.
BIT code, VxWorks and Functional Test software switches
off these LEDs as it runs. Notionally, each LED is
associated with each core of the 8641D.
BIT code may adjust its use of these LEDs to indicate
different stages of MPE (Minimum Processing
Environment) progress.
Ordinarily, user software should not make use of these
LEDs unless BIT code is not present, in which case the BSP
and or user code should switch them off
