• Use i2cdetect to scan I2C Bus 1 at the PMIC I2C address 0x30. This displays an output table, where the UU at cell 0x30 indicates the address is currently in use by the TPS65219 driver.

  >i2cdetect -y 1

• Check the PMIC regulator details within the /sys/class/regulator/ directory. For further explanation, refer to this kernel.org documentation: kernel.org

  >cat /sys/class/regulator/regulator.7/name
  >cat /sys/class/regulator/regulator.7/microvolts
  >cat /sys/class/regulator/regulator.7/type

• In a new terminal, verify the VDD_SOC voltage supply using the bcu command:

  >sudo bcu monitor -board=imx93evk11b1 -temp
