− | | This triggers ARM11 kernel [[I2C]] code, Param0-Param3 are unused. This ARM11 kernel I2C code will never return. Device address 0x4a via the second I2C bus is used here. This triggers a hardware system reboot via poking an I2C MCU register: register address 0x20 is written to with value 4. | + | | This triggers an MCU (hard) reboot. Param0-3 are unused. This reboot is triggered via device address 0x4A on the second [[I2C]] bus (the MCU). Register address 0x20 is written to with value 4. This code will not return. |
