Embodiment 1

[0054] figure 1 A schematic diagram of the implementation flow of the Flash programming method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes:

[0055] Step 110: After creating the download thread of the serial port of each Flash programming board, run the download thread of the serial port of each Flash programming board.

[0056] Here, the Flash programming host computer is a PC, and the PC is equipped with Flash programming software. There can be one or more single boards for Flash programming. For example, there are 32 boards for Flash programming. Each Flash programming board is connected to the serial port of the USB-to-serial cable, the USB end of the USB-to-serial cable is connected to the USB hub (Hub), and the USB Hub is connected to the USB port on the PC side through its own USB cable. The USB port of the flash programming board is connected to the USB flash drive. The flash programming board is powered on usi...

Embodiment 2

[0102] Embodiment 2 of the present invention provides another Flash programming method, the method comprising:

[0103] Step 210: run the second file according to the running result of the download thread of the single-board serial port written by Flash, and read the first image file in the USB flash disk according to the running result of the second file, wherein the first image file Includes microkernel with root filesystem.

[0104] Step 220: According to the operating results of the microkernel and the root file system, the flash programming single-board Flash is partitioned and formatted, and the second image file in the USB flash disk is burned to the Flash Program the single-board Flash.

[0105] Such as Figure 5 Shown, described according to the operation result of described microkernel, carry out partition operation to each Flash programming single-board Flash comprises:

[0106] start the microkernel;

[0107] When identifying the single-board Flash written by t...

Embodiment 3

[0112] Embodiment 3 of the present invention provides another Flash programming method, the method comprising:

[0113] Step 310: After creating the download thread of the serial port of the Flash programming board, run the download thread of the serial port of the Flash programming board.

[0114] Such as Figure 4 As shown, the download thread of the Flash programming board serial port includes:

[0115] initialization;

[0116] Send a download command to the Flash programming board;

[0117] Send the download address to the Flash programming board;

[0118] Send the first file size and the second file size to the Flash programming single board;

[0119] Send the first file and the second file to the Flash programming single board;

[0120] Send an execution command to the Flash programming board;

[0121] Send the execution entry address to the Flash programming board;

[0122] Finish.

Abstract

The invention provides a Flash burning method comprising the steps of after creating a downloading thread of each Flash burning single board serial port, operating the downloading thread of each Flash burning single board serial port; operating a second file according to the operating result of the downloading thread of each Flash burning single board serial port and reading a first mirror image file in each USB flash disk according to the operating result of the second file, wherein each first mirror image file comprises a micro-core provided with a root file system; performing partition and formatting operations on each Flash burning single board Flash according to the operating results of the micro-cores and the root file systems and burning a second mirror image file of each USB flash disk to each Flash burning single board Flash. The invention also provides a Flash burning single board, upper computer and system.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a flash memory (Flash) programming method, a single board, a host computer and a system. Background technique [0002] With the development of science and technology, set-top box technology has become a well-known science and technology for the public. The set-top box is a device that connects a TV set with an external signal source, and can convert compressed digital signals into TV content data and display them on the TV set. Digital signals come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. In addition to the images and sounds that can be provided by analog TV, the data received by the set-top box can also receive digital signals, wherein the digital signals include electronic program guides, Internet pages, and subtitles. The digital signal received by the set-top box enables users to watch digital TV programs on the TV, and enables use...
