Table 7. EVM Configuration Switch Function
Switch
Name
Default
Condition
Signal
Operation
SW3.1
OFF
OSPI/HYPER_MUX_SEL
MUX to select between non-volatile memories:
‘0’ (OFF) = OSPI Memory connected to MCU_OSPI0 Interface
‘1’ (ON) = Hype HyperRAM connected to MCU_OSPI0 Interface
SW3.2
ON
TRACE/GPMC_MUX_SEL
MUX to select Trace interface for debug:
‘0’ (OFF) = Selected signals used for other peripherals (non-debug)
‘1’ (ON) = Debug/Trace connected to MIPI-60 emulation interface
SW3.3
OFF
USBC_MODE_SEL1
Set Mode for USB Type C interface (USB0):
'00' (OFF/OFF) = DFP (Downstream Facing Port)
SW3.4
OFF
USBC_MODE_SEL0
‘01’ (OFF/ON) = DRP (Dual Role Port)
‘1X’ (ON, Don’t Care) = UFP (Upstream Facing Port)
SW3.5
OFF
PCIe_1L_MODE_SEL
PCIe 1-Lane Interface Mode Select (supports port PCIe0)
‘0’ (OFF) = Root Complex
‘1’ (ON) = End Point
SW3.6
OFF
PCIe_2L_MODE_SEL
PCIe 2-Lane Mode Select (supports port PCIe1)
‘0’ (OFF) = Root Complex
‘1’ (ON) = End Point
SW3.7
ON
CSI_VIO_SEL
Sets I/O voltage for CSI2 Expansion Interface (LVCMOS signals)
‘0’ (OFF) = 1.8V I/O Voltage
‘1’ (ON) = 3.3V I/O Voltage
SW3.8
ON
INFO_CAM_VIO_SEL
Switch is to be used on Expansion board. See specific expansion board User’s
Guide for definition.
SW3.9
ON
BOARDID_EEPROM_WP
Sets EVM’s configuration EEPROM Write Protection
‘0’ (OFF) = Configuration EEPROM can be updated
‘1’ (ON) = Configuration EEPROM cannot be updated/protected
SW3.10
ON
USER_INPUT1
User Define, maps to I/O Expander Input
‘0’ (OFF) = User Defined
‘1’ (ON) = User Defined
