Preface
..................................................
With the continuous development of intelligence and AI, the using of MCUs are exploding. As we all know, MCU needs to be programmed on the production side, that is, to write the target binary data into the chip to perform special functions of the product. Therefore, chip programming is the most important procedure in the mass production state. Whether the product has abnormalities or functional problems is related to whether the chip programming is correct or not. In fact, many problems such as wrong import of raw data, incorrect chip parameter settings, incorrect configuration data or abnormal programming data will directly lead to product functional fault. Some problems can be discovered during testing, while others may be discovered during end-user usage. Therefore, in order to ensure stable product quality and performance, data burning in the production process is particularly important.
How to ensure the correctness of programming is a problem faced by production engineers. But chip programming is a very special processing. First, the programming details and data information cannot be seen. Second, the operator cannot know whether the user's settings and requirements have been implemented or executed. On the other hand, it is also uncertain whether the burn-in device has completely imported the original data correctly into the chip. Finally, it is assumed that there is no problem with the programming device, but if the operation does not meet the relevant specifications of the chip, it will also affect the functionality of the chip. All of these increase the product risk after chip programming. If the programming errors and anomalies cannot be verified during the testing phase, it may cause anomalies and problems after the product leaves off the factory, and may leads to serious problems.
Solution
..................................................
Based on these problem, in addition to improve reliability and performance of the programmer, how to carry out third-party confirmation and verification of existing equipment during operations, it became effective way to prevent the risk of chip programming. The programming signal and waveform is captured by the logic device, thereby transforming the abstract programming process into a perceptible and visual data flow. By analyzing the data stream and the captured waveform, compare with the actual programming information of the chip, it can be verified whether the programming process is correct. In this way, the abstract imperceptible operation is digitized and visualized, thereby effectively preventing unpredictable problems caused by human and equipment operation defects.
The programming authentication service is proposed based on this requirement. First, clarify the specific chip programming requirements and functional operations of each project, capture each signal and data stream in the entire programming process, and then compare to the chip programming protocol to analyze the protocol and data stream, so as to confirm whether the operation of this programming meets the specifications, whether the established functions and requirements are realized? whether there are any steps lost? whether there are any operations that should not be performed? whether the waveform are matched to the design specifications of the chip? and whether the voltage level meets the chip? etc. Therefore, the correctness and integrity of the programming device or the set of operation can be guaranteed from another aspect.
