I2C Address Mapping

There are three I2C interfaces used in AM62x SIP SK EVM board:

  • SoC I2C 0 Interface: SoC I2C [0] is connected to Board ID EEPROM, User Expansion Connector Header, USB PD controller, PRU header, and OLDI Display Touch interface.
  • SoC I2C 1 Interface: SoC I2C [1] is connected to Test Automation Header, Current Monitors, Temperature Sensors, Audio Codec, HDMI Transmitter, CSI Camera Connector, GPIO Port Expander.
  • SoC I2C 2 Interface: Connected I2C [2] from SoC to the User Expansion Connector Header.
  • MCU I2C 0 Interface: Connected MCU I2C [0] to MCU Header.
  • WKUP I2C 0 Interface: Connected I2C [0] from SoC to LED Drive.
