6.11 Jumper description
Please note that most the jumpers on the board are SMT type. If you feel insecure of your
soldering/cutting technique it is better not to try to adjust the jumpers since it is possible to damage
the board.
Board jumpers
Jumper name
Type
Default position
Function
NAND_E
SMT
Either CLOSED or
OPEN, depending
whether the board
has 4GB NAND
MEMORY MODULE
Controls whether the NAND memory
module is enabled or disabled.
If the jumper is closed than the
NAND memory is operational.
PC3/PB8
SMT
PC3
Controls which processor pin should
be used for SATA power enabling
signal. By default the SATA
powering control uses processor pin
L22 which is port PC3.
Changing this jumper also changes
the availability of PC3 and PB8 at
GPIO-1 pin 29 and GPIO-3 pin 16.
Please note that if you change the
position of the jumper from PC3 to
PB8 then you might block one of the
processor pins responsible for I2S
and AC97 audio output.
PB9/PH7_USB
SMT
PB9
Controls which processor pin should
be used for the USB_OTG. By default
the USB_OTG uses processor pin C12
which is port PB9. The same
pin/port is used for I2S audio. In
case you want to access the I2S
capabilities of the board you would
need to change the default
position.
PB9/PH7_GPIO
SMT
PH7_GPIO
PB9/PH7_GPIO jumper controls which
of the two ports (PB9 or PH7)
should be lead out to pin 9 of
GPIO3 connector for easier access.
Changing this jumper also changes
the signal available at GPIO-3
connector's pin 9.
By default this jumper is in
PH7_GPIO position and PH7 is lead
to pin 9 of GPIO3.
