Error detection method and system for CDRW

Abstract

The invention discloses a burning error detection method and a system thereof. The system comprises a server which stores a source code file and a source code verification code corresponding to the source code file; a controller which is electrically connected with the server and is used for executing a transcoding program, can transcode the source code file into a burning data file and generates a burning verification code corresponding to the burning data file; a chip conveying device which is electrically connected with the controller and is used for transmitting at least one chip; and a burning device which is electrically connected with the controller and is used for receiving the chip transmitted by the chip conveying device, can execute a burning program to write the burning data file into the chip, and then execute a read program to read the data file originally written into the chip so as to obtain a read data file, and the controller executes a data check program to detect whether the data written by the burning program is correct or not.

Description

Technical field [0001] The present invention relates to a recording method and system, in particular to a recording method and system with error detection capability. Background technique [0002] OTP (One-Time Programmable) stands for one-time programmable EPROM. General EPROM has windows that provide ultraviolet (UV ray) erasing data. It needs to be made of expensive quartz glass (general glass blocks ultraviolet light), and because it is embedded in the quartz glass window, a high-cost ceramic package must be used, while OTP EPROM It only needs to use a cheap plastic package, which has the advantages of not being affected by ultraviolet rays and greatly reducing the cost. [0003] Since OTP EPROM does not have a window for erasing data, it needs to be burned by a manufacturer that can perform OTP burning. The customer provides the source code file that needs to be burned, and the manufacturer transcodes it into a local code file according to the characteristics of individual O...

Problems solved by technology

[0004] Since OTP recording needs to go through the above-mentioned multi-stage process, it is difficult to know which stage is wrong if the content of the recording is found to be wrong after OTP burning is completed. The main possible reasons for the error are as follows: the content of the source file provided by the customer is wrong, Errors in coding cause errors in native code files, errors in compilation process cause errors in binary code files, errors in planting other binary code files to the burner and OTP engraving process

[0005] Since OTP burning requires multiple stages of the process, it also causes many possible reasons for errors. When OTP burning is found to fail the test, it is not easy to track which stage the error occurred. Even if the cause of the error is traced, a large number of errors may have occurred Wrong finished product, causing a lot of losses
