Table 1. Jacinto7 EVM Common Processor DIP Switches Used for Expansion Boards

Switch Name Default Condition Signal Operation
SW3.8 ON INFO_CAM_VIO_SEL ‘1’ (ON) =3.3V will be selected from LDO for camera IO voltage
‘0’ (OFF) =1.8V will be selected from LDO for Camera IO Voltage
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
