J7 Jumper J7 configures the operation mode
(normal operation / test mode) of the TC358764 DSI2LVDS
Bridge Chip mounted at U8 Section 2.1.3.7.1
1+2 Test mode enabled
2+3 Normal operation; test mode disabled
J8 In combination with jumpers J3 and J8, and resistors R25
and R26 jumper J8 allows to configure the various
operating modes of the RS-232 transceiver at U2.
J8 connects jumpers J3 and J4 (and in further consequence
the Force-On and Force-Off inputs of the RS-232
transceiver) to GND, or the /Invalid output. Section 2.1.3.3.2
open Jumpers J3 and J4 are neither connected to GND nor to the
/Invalid output. FORCEON and /FORECOFF are pulled HIGH
by pull-up resistors R25 and R26
1+2 Depending on the configuration of jumpers J3 and J4
FORCEON, or /FORECOFF, or both inputs are connected to
the /Invalid output of the RS-232 driver.
2+3 Depending on the configuration of jumpers J3 and J4
FORCEON, or /FORECOFF, or both inputs are connected to
GND_RS232.
J9 Jumper J9 configures the I
2
C address of the touch screen
controller at U41
Section 2.1.3.7.3
1+2 I2C device address set to 0x41
2+3 I
2
C device address set to 0x44
J10 Jumper J10 selects the source of the reset signal at
phyCAM-P interface connector X4. The camera reset can be
triggered either by the system reset of the PMIC on the
phyCORE-OMAP44xx, or the OMAP44xx's camera sensor
reset signal X_CAM_GLOBAL_RESET Section 2.1.3.9.2
1+2 Camera reset is triggered by the PMIC's system reset
signal X_nRESET_PWRON
2+3 The camera sensor reset signal X_CAM_GLOBAL_RESET
resets a camera connected to X4
