Hardware Preparation
When a jumper is placed between positions 1–2 of JP9, the hard reset configuration source
is a memory (FLASH/EEPROM) as configured by switch SW6-1. When a jumper is set
between positions 2–3 of JP7, the hard reset configuration source is the BCSR. See

Setting Boot Source
The hard-reset configuration word, read by the MPC8272 while HRESET is asserted, may
be taken from the following sources:
?
?
?
Flash memory SIMM
EEPROM
BCSR
(In fact, eight hard-reset configuration words are read by a configuration master; however,
only the first is relevant for a single MPC8272.)
For additional information about the contents of the hard-reset configuration word, see
Section 5.1, “Reset and Reset Configuration.”
SW2#1 actually assigns CS0 to the FLASH (default when booting from the BCSR) or to
the EEPROM. When SW2 #1 is OFF, the hard-reset configuration word is taken from
EEPROM. When it is ON, the hard-reset configuration word is taken from the Flash SIMM
(see Figure 2-5).
