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) = HyperFlash + 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
