Description
182 BOOT_MODE0 BOOT_MODE0/
T10 I, 3.3V CMOS/
4.7K PU Boot Mode Select bit0.
Important Note: This pin is directly connected
to i.MX6UL/i.MX6ULL
CPU’s BOOT_MODE0
pin with On- SOM pullup and so don’t add any
external pullup in carrier board on this pin.
Make sure to use this pin in carrier board to
select desired boot mode by driving only low
if required.
183 VRTC_3V0 NA I, 3V Power 3V backup coin cell input for RTC.
184 BOOT_MODE1 BOOT_MODE1/
U10 I, 3.3V CMOS/
4.7K PU Boot Mode Select bit1.
Important Note: This pin is directly connected
to i.MX6UL/i.MX6ULL
CPU’s BOOT_MODE1
pin with On- SOM pullup and so don’t add any
external pullup in carrier board on this pin.
Make sure to use this pin in carrier board to
select desired boot mode by driving only low
if required.
185 GND NA Power Ground.
186 GND NA Power Ground.
187 POR_B POR_B/
P8 I, 3V CMOS Active low reset button input.
Important Note: This pin is directly connected
to i.MX6UL/i.MX6ULL
CPU’s POR pin which
has internal pullup and so don’t add any
external pullup in carrier board on this pin.
Also use this pin only for connecting the reset
push button in carrier board.

191 JTAG_TDO/SAI2_TX_S
YNC JTAG_TDO/
N15 O, 3.3V CMOS JTAG Test Data Output.
Note: Same signal is also connected to 89
th
pin of SODIMM edge connector.
192 VIN_3V3 NA I, 3.3V Power Supply Voltage.
193 JTAG_TRST_B/SAI2_TX
_DATA JTAG_TRST_B/
N14 I, 3.3V CMOS JTAG reset.
Note: Same signal is also connected to 67
th
pin
of SODIMM edge connector.
194 NC NA - NC.
