Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0024] The multifunctional SPI flash burning method designed by the present invention encrypts the file to be burned to form a ciphertext with a key, and encrypts the key to form a key ciphertext;

[0025] Store the decryption key of the decrypted ciphertext and the key ciphertext in the burner, and encrypt and protect the secret key of the decrypted key ciphertext;

[0026] The ciphertext and key ciphertext are restored to the burning file through the decryption key in the burner, and then the burning operation is performed through the SPI communication module;

[0027] The protocol script edited by the host computer is run and processed by the burner, and the command transparent transmission is completed through the SPI communication module and then fed back to the host computer.

[0028] In order to achieve better confidentiality, the b...

Abstract

The invention discloses a multifunctional SPI flash burning method, which includes steps of encrypting a file to be burned to be a ciphertext through a key; encrypting the key to form the key ciphertext; storing a decrypting key for decrypting the ciphertext and the key ciphertext in the CD-R machine, and encrypting the key for decrypting the key ciphertext; restoring the key ciphertext and the key key ciphertext to be a burning file through the decrypting key and then performing the burning operation through an SPI communication module; running a protocol script edited by an upper computer bythe CD-R machine, wherein an order passes through the SPI communication module and then feeds back to the upper computer. The invention further discloses a multifunctional SPI flash CD-R machine. TheCD-R machine can be debugged and can realize the purpose of encryption and rapid burning during the burning process.

Description

technical field [0001] The invention relates to the field of programming, in particular to a multifunctional SPI flash programming method and a programming device. technical background [0002] At present, the SPI flash programmers on the market are controlled through the network port or USB port of the host computer, and perform full erasing, partial area erasing, full writing, partial area writing, full reading, partial area reading and automatic operation. Such as erasing, writing, reading, comparing. In actual use, the operation of SPI flash is completed by SPI bus protocol instructions one by one. The above-mentioned programmer cannot transparently transmit instructions to the user, and the function is very closed, and the user cannot track, inspect, and debug. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and provides a multifunctional SPI flash programming method and a programmer that can be debugged and realiz...
