I2C Address Mapping

There are five AM62P I2C instances communicating with the various peripherals in the SKEVM.

  • SoC_I2C0 Interface: SoC I2C[0] is connected to Board ID EEPROM, User Expansion Connector, USB PD controller, OLDI display connector and DSI display connector.
  • SOC_I2C1 Interface: SoC I2C[1] is connected to Test Automation Header, Current Monitors (x6), Temperature Sensors (x2), Audio Codec, HDMI Transmitter & GPIO Port Expander (x2).
  • SOC_I2C2 Interface: SoC I2C[2] is connected to the User Expansion Connector and CSI Camera connector.
  • MCU_I2C0 Interface: MCU I2C[0] is connected to the MCU Header & PMIC.
  • WKUP_I2C0 Interface: WKUP I2C[0] is only connected to the PMIC.

The image below depicts the I2C tree, and the below table provides the complete I2C address mapping details present on the AM62P SK EVM.
