Problems solved by technology
[0005] In order to overcome the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a chip mass production platform system and its implementation method to solve the problem of using the simulation compiler and MDK project to download the user application software when the user produces products in small batches. When the chip is programmed online, the flexibility is poor, the production cost is high, and the efficiency is low

Embodiment
[0068] In this embodiment, a chip mass production platform system of the present invention is divided into two parts, one is the chip firmware end, and the other is the PC end, and the working process of the two parts is as follows: image 3 As shown, the specific working process is as follows:
[0069] The first step is to burn the system boot add-on on the firmware side.
[0070] Generally, the Bootloader program code can be directly solidified to the chip memory BOOT area during factory production, and when the chip firmware side is ready, wait for the command sent from the PC side. The tester only needs to operate the PC-side interface and connect the serial port data cable, and does not need to operate the firmware side.
[0071] In the second step, the firmware side downloads the user application software APP program. Its basic principle is as follows: After inserting the serial port data cable connected to the chip firmware end, open the PC end GUI interface. In this ...

The invention discloses a chip mass production platform system and an implementation method thereof. The system comprises a chip firmware end which is used for obtaining a Bootloader program and storing the Bootloader program in a chip memory BOOT area, and is connected with a PC end through a serial port data line to download a user application program from the PC end to the chip firmware end after communication between the PC end and the chip firmware end is established,, receive a CRC result sent to the chip firmware end by the PC end after the user application program is downloaded, andstore the received CRC result data into a specific memory area; the system further comprises the PC end which is used for downloading the user application program to the chip firmware end according tothe selected downloading path of the user application program after being connected with the chip firmware end through the serial port data line, and sending the CRC check result to the chip firmwareend after the downloading is finished.
Description
technical field [0001] The invention relates to the technical field of chip manufacturing, in particular to a chip mass production platform system and an implementation method thereof. Background technique [0002] The R&D process of embedded electronic products will go through several major processes of R&D design, small-batch trial production, and mass production in chronological order. Among them, small-batch trial production is an intermediate process, which is a process for supplementary verification of R&D design, connecting R&D design and mass production in series, and is an indispensable intermediate link from R&D design to mass production. The user application program design (that is, software design) in the early stage of R&D and design is debugged and programmed online with a simulation compiler. Later, when the user application program is developed and needs to be mass-produced, the programmer is generally used to perform offline programming. However, in the sma...
