The update start will perform a reset of the device and start the maintenance firmware.
If a valid update file is available, it will be automatically processed and installed. If no update file is available or if the update file is not valid, the maintenance firmware will change into error mode, changes the SYS LED (to yellow on) and sets an error code (e.g. ERR_HIL_NOT_AVAILABLE,0xC0001152).
The PC utility netHOST can be used to send the HIL_FIRMWARE_RESET_REQ command through the UART Marshaller, or the mailbox packet can be sent in the user application code.
The "Boot Start Reset" processes the same action as the above packet command.
