Embodiment 1

[0028] The vehicle-mounted terminal system upgrade burning encryption method includes a burning device, and the burning device includes a burning controller, an indicator light, a host computer, a power supply and a button controller, and the method flow of the burning device is as follows:

[0029] Sp1: The programming device is connected to the host computer of the computer through the USB interface. The host computer can control each ST-Link, and can also communicate with the controller of the programming device to control the power supply, indicator light and button controller of the programming device;

[0030] Sp2: Determine the burning data of the device to be burned, and input the burning data through the host computer;

[0031] Sp3: Encrypt the entered burning data, input the encrypted data into the host computer, and encrypt the whole burning process;

[0032] Sp4: Burning starts, confirm the burning status by observing the color display of the indicator light;

[0...

Embodiment 2

[0037] The vehicle terminal system upgrades the burning encryption process, and the encryption process flow is as follows:

[0038] Sp1: Before the burning starts, the host computer connects to the burning device, generates a user key through the client side of the host computer, and transmits the user key to the burning encryption client;

[0039] Sp2: When burning, use the key to unlock the burning device, and set an encryption applet on the burning burning device. After unlocking the burning device, use the encryption applet to encrypt the burning data. Before starting, first unlock the burning data in the encryption applet and then unlock the burning device;

[0040]Sp3: Differentiate and identify each ST-Link through the unique code of ST-Link, and the encrypted data of ST-Link connected to each burning device is different, independently control each ST-Link through the host computer, and load the firmware file , identify the chip, and complete the programming timing log...

Abstract

The invention provides a vehicle-mounted terminal system upgrading burning encryption method and an encryption process thereof, and relates to the technical field of burning; the method comprises a burning device; the burning device comprises a burning controller, an indicating lamp, an upper computer, a power supply and a key controller, and the method of the burning device comprises the following steps: Sp1, connecting the burning device to an upper computer through a USB interface; sp2, determining burning data of equipment to be burnt; sp3, carrying out encryption operation on the input burning data, inputting the encrypted data into the upper computer, and encrypting the whole burning process; sp4, starting burning, and determining the burning state by observing the color display of a indicator lamp; and Sp5, after the burning of a single burning device is finished, continuing to carry out burning work on a next burning device. According to the invention, encryption of the burning device in the burning process is achieved, the burning device which can intervene in multiple ST-Links can be achieved, and the production benefits of the burning device are improved.

Description

technical field [0001] The invention relates to the field of programming technology, in particular to an encryption method for upgrading and programming a vehicle-mounted terminal system and an encryption process thereof. Background technique [0002] Chip programming is to burn files, such as Hex files, Bin files and other files containing program codes, into the chip program memory, so that the chip can work. Chip programming requires programmer software and programmer hardware. The function of the burner software is to send the burning file to the burner hardware. The burner hardware stores the file and burns the data of the file into the chip. If the burner hardware has a storage function, it can realize Offline programming is convenient for batch programming. The burner hardware can realize the control of burning times. The burner hardware of this patent needs to have storage function. [0003] The end customer is the party that will burn and produce the final batch...
