DF_E
Default state
The RXD1/DRXD jumper defines which pin - RXD1 or DRXD -
is connected to the RS232 driver (ST3232), i.e. the board
allows
DRXD.
RXD1 position – RXD1 function of SAM9260 pin 18 is tied to
pin12(R1OUT) of U6(ST3232).
DRXD position – DRXD function of SAM9260 pin 21 is tied to
pin12(R1OUT) of U6(ST3232).
Default state
The TXD1/DTXD jumper defines which pin - TXD1 or DTXD -
is connected to RS232 driver (ST3232), i.e. the board allows
comunication with PC COM port through TXD1 or DTXD.
TXD1 position – TXD1 function of SAM9260 pin 17 is tied to
pin11(T1IN) of U6(ST3232).
DTXD position – DTXD function of SAM9260 pin 22 is tied to
pin11(T1IN) of U6(ST3232).
Default state
PHY_PDE position – The PHY chip U7(KS8721BL) enter to
power down mode.
PHY_PDCTRL position – The PHY chip power down mode is
controled from SAM9260 PC1(pin58).
OPEN position – The PHY chip is alwаys enabled.
Default state- open
The
SAM9260 to control CE pin of NAND FLASH memory
U3(K9F4G08UXM). If the board has to boot from NAND flash
the NANDF_E jumper must be closed.
The
SAM9260 to control CS pin of serial Data Flash memory
U5(AT45DB161D-SU). If the board has to boot from Data Flash
the DF_E jumper must be closed.
Default state- close
