J11
Jumper J11 connects the shield contact of audio jack X14
(headphone out) to either GND, or the HPCOM output
driver of the stereo audio codec at U43. Connecting the
shield contact to HPCOM allows to use the jack detection
function of the stereo audio codec.
1+2
Shield contact connected to the HPCOM output driver of the
stereo audio codec, jack detection enabled
2+3
Shield contact connected to GND, jack detection
disabled
J12
Jumper J12 configures the level of the supply voltage for
the SD / MM card interface at connector X10
1+2
VCC_3V3 connected to VCC_SDMMC5
2+3
VCC_1V8 connected to VCC_SDMMC5
J13
Jumper J13 configures the source for the audio codec's
master clock. The clock can be generated either on the
phyCORE-OMAP44xx (pin X_FREF_CLK4_REQ), or an
oscillator at OZ1 on the carrier board.
1+2
Pin MCLK of the audio codec connected to oscillator OZ1
(19.2 MHz)
2+3
Pin MCLK of the audio codec connected to
X_FREF_CLK4_REQ (X1D29) of the phyCORE-OMAP44xx
J14
Jumper J14 configures the source for the master clock at
the phyCAM-P interface connector X4. The clock can be
generated either on the phyCORE-OMAP44xx
(pin X_FREF_CLK4_OUT), or an oscillator at QO1 on the
carrier board.
1+2
CAM-2_MCLK connected to oscillator QO1 (26 MHz )
2+3
CAM-2_MCLK connected to X_FREF_CLK4_OUT (X1B13) of
the phyCORE-OMAP44XX
J20
J20 selects rising, or falling edge strobe for the FlatLink™
transmitter at U32 used for the display connectivity of the
phyCORE-OMAP44xx
