Firmware is software embedded in a hardware device, such as a program executed by a computer. Currently, firmware is widely used in various electronic products, such as remote controllers, computers, keyboards in computers, displays, hard disks, industrial robots, etc. With the advent of media technology, firmware update can ensure that the hardware (hard ware) of electronic products is kept in the latest state and ensure compatibility, thereby improving hardware performance and reliability.
The update data of the new firmware is usually issued by the hardware manufacturer or software designer in order to repair bugs of the old firmware, improve performance, increase functions, or improve security vulnerabilities. Typically, the firmware update operation is performed by downloading a new firmware update file from a network or a storage medium (e.g., an external computer, a flash drive, a memory card, or the like), and then updating the old firmware file in the hardware device by performing a current clearing, a rewriting operation, or a replacement operation on the storage medium.
The first method is that the user inserts a portable disk storing a new version of firmware update file of the display into the display, and then starts the firmware file and program update flow from the on-screen display (OSD) of the display. The second method is that the user uses a Universal Serial Bus (USB) connection line to connect to the computer to download the new firmware update file, and then uses the command of the external computer to update the firmware file and program.

In this embodiment, the image scaling controller 401 can switch the host configuration of the upstream data flow port 403a of the near USB device 403 (USB hub) to the operation systemA system chip 409, and a user interface device controller/integrated bus (HID over I) 2 C) The bus 408 and the USB device 403 transmit the address of the remote server 42 to the OS chip 409 to start the firmware update operation. In some embodiments, the image scaling controller 401 can also switch the usb active port 404c of the ethernet/usb module 404 to the os chip 409 (refer to step S421B).
Then, the USB/IP server software program is executed by the OS chip 409, and the remote server 42 responds to the update request 417 of the OS chip 409 to open the firmware update data in the remote USB device 405 and connect to the OS chip 409 (refer to step S422). In this embodiment, the OS chip 409 executes the USB/IP server software program, sends the update request 417 to the remote server 42, and starts the display update program 410 stored in the remote USB device 405. The display update process 410, upon receiving the update request 417, knows the address of the OS chip 409 via the packet source, and instructs the remote server 42 to execute the USB/IP client software process to connect to the OS chip 409.
Then, the display update program 410 in the remote USB device 405 starts the firmware update data 407 (refer to step S423). In this embodiment, the display update program 410 of the remote USB device 405 first detects the UI device controller 411 shared by the OS chip 409 and the USB device 403, and then sends a command to obtain data related to the display 40 via the UI device controller 411, and opens a corresponding firmware update file according to the data of the display 402.
Subsequently, the display update program 410 in the remote USB device 405 transmits an update command and firmware update data 407 via the UI device controller 411 to update the firmware configuration of the display 405 (see step S431). The host configuration of the upstream data flow port 403a of the near USB device 403 (USB hub) is switched to the previous external computer 43 (see step S432).
