The jumpers (J = solder jumper) have the following functions:
Jumper
Description
Type
Chapter
J2, J1, J3
J2, J1 and J3 define the slave addresses (A0 to A2) of the
serial memory U2 on the I
2
C1 bus. In the high-nibble of the
address, I
2
C memory devices have the slave ID 0xA.
The low-nibble is build from A2, A1, A0, and the R/W bit.
0R (0402)
all 1+2 A0 = 0, A1 = 0, A2= 0, => 0x0 / 0x1 (W/R) are selected as
the low-nibble of the EEPROM's address
other settings please refer to
to find alternative addresses
resulting from other combinations of jumpers J1, J2, and J3
J4
J4 connects pin G5 of the NAND-Flash at U4 to 1.8 V or GND.
On many NAND memory devices pin G5 enables/disables
the activation of the lock function.
It is not guaranteed that the standard NAND memory
populating the phyCORE-OMAP44xx will have this lock
function.
Please refer to the corresponding NAND memory data sheet
for more detailed information.
0R (0402)
1+2 or
open NAND-Flash U4 not locked
2+3 NAND-Flash U4 locked
J5
J5 connects pin 7 of the serial memory at U2 to GND.
On many memory devices pin 7 enables/disables the
activation of a write protect function.
It is not guaranteed that the standard serial memory
populating the phyCORE-OMAP44xx will have this write
protection function.
Please refer to the corresponding memory data sheet for
more detailed information.
0R (0402)
open EEPROM U2 is write protected
closed EEPROM U2 is not write protected
J6
J6 connects either pin AH24 (DMTIMER9) or pin AG12
(USBB2_ULPITLL_CLK) of the OMAP44xx controller U1 to
pin 43A (X_DMTIMER9) of the phyCORE-Connector X1.
0R (0402)
1+2 Pin AH24 (DMTIMER9) of controller U1 is connected to
phyCORE-Connector X1, which means that pin X1A43 can
be used as PWM output for brightness control
2+3 Pin AG12 (USBB2_ULPITTL_CLK) of controller U2 is
connected to phyCORE-Connector X1
