I have a NANO 945-13450-0000-000 platform. if I used SDK manager to flash . the avaiable space is only 14G.
During the flash I also see err while syncing system image as following but the flashing seems sucessful in the end.
On the target i recalled i saw the log after creating the login information . it prints err like failed to boot resizing the sd card then after that it boots fine and the acutally avaiable sd card size is only 14G if i type df from the terminal.
