Embodiment Construction

[0016] The application will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 2 As shown, it is a schematic flow chart of a method for chip download startup program provided by this application, such as figure 2 As shown, an embodiment of the method for the chip download startup program provided by the application includes:

[0018] S101. Determine the download identifier in the startup program of the chip to be downloaded.

[0019] After the system is powered on, the chip needs the corresponding chip startup program to complete the startup, enter the normal working state, and realize the normal function of the chip. Due to the limited storage space inside the chip, before the chip is started, the chip startup program is generally stored in the ROM, such as image 3 The chip startup program shown is a piece of program code that contains multiple field information, including the program field header, function field and fiel...

Abstract

The embodiment of the present application discloses a method for downloading a startup program of a chip, a chip and an LCD TV, including: determining a download identifier in the startup program of the chip to be downloaded, and setting the download identifier in the last byte of the startup program of the chip; downloading the chip startup program; and controlling the downloading of the chip startup program according to the detection result of the download flag. The download flag is set at the last byte of the chip boot program. If the download of the chip boot program fails, the information of the last byte will not be detected. Correspondingly, before the chip downloads the chip startup program, the chip cannot start, so the register value will not change. If the download flag is detected or the value of the monitored register has not changed. Then re-download the chip startup program, thereby preventing the problem that the chip startup program fails to download.

Description

technical field [0001] The present application relates to the technical field of chip downloading, in particular to a method for chip downloading and starting programs, a chip and a liquid crystal television. Background technique [0002] TCON (Timing Controler, Timing Controller) board is a LCD panel driver board widely used in LCD TVs. The main function of the TCON board is to send image data signals (including RGB data signals, clock signals and control signals) to the LCD TV motherboard. Three types of signals) After processing, it is converted into a data signal that can drive the LCD screen, and then directly sent to the SCOF IC of the LCD screen. There is a chip with image processing function on the TCON board. When the LCD TV is powered on, the chip on the TCON board needs to download the startup program from the ROM in the internal processor of the LCD TV, and complete the normal startup of the chip according to the downloaded startup program. [0003] Since the ch...
