The result of the download will depend on whether the boot_up option has been specified. Case 1: In the case of the master unit providing the file system and the slave unit not providing the file system, when the boot_up parameter is specified, then the file will be downloaded to the boot_up image on the slave. If the boot_up parameter is not specified, then the file will not be downloaded to this slave unit. Case 2: In the case of the master unit not providing the file system and the slave unit providing the file system, when the boot_up parameter is specified, then the file will be downloaded to the boot_up image on the slave unit. If boot_up is not specified, then the file will not be downloaded to this slave unit. Case 3: In the case of the master unit and the slave unit both supporting or not supporting the file system, the file will be downloaded to the specified file on the slave unit. If boot_up is specified, the downloaded file will be assigned as the boot_up image. True: boot_up option is specified. False: boot_up option is not specified..
