Abstract

The invention discloses a chip burning checking method, which comprises the following steps that S1, users set required burning checking parameters on burning checking equipment; S2, the burning checking equipment carries out detection; S3, the chip sequence number ID (identity) is sequentially subjected to reading, calculation, burning and checking; S4, chips subjected to the sequence number ID checking are sequentially subjected to file byte data reading, calculation, burning and checking; S5, the chips subjected to the file byte data checking are subjected to burning state protection bit calculation and checking. The chip burning checking method has the advantages that the communication mode is converted into a parallel mode from a serial mode, the burning-while-checking-verifying multi-channel single comparison mode is adopted, abnormal burning links are discovered in time, abnormal test channels are judged in time, the integral testing efficiency of the burning checking is improved, the channel contact electrification condition is effectively distinguished, the reverse insertion and mistake insertion of the channels can be prevented, and the occurrence of quality accidents caused by plate taking error can be effectively avoided.

Description

technical field [0001] The invention relates to chip programming and verification technology, in particular to a method for realizing BQ2022A programming verification. Background technique [0002] With the development of electronic technology and the increasing demand of consumers for electronic equipment, the introduction of BQ2022A new power management IC, the import procedure includes programming verification comparison and verification sum calculation and programming, and it is required to ensure that the only There are technical difficulties, and the stability of the burning process is difficult to guarantee. The current industry production method is based on the software and hardware (EV2300) provided by TI (Texas Instruments Corporation), and realizes the programming verification comparison of BQ2022A through a single channel in a purely manual manner. This method is restricted by TI company, which has great limitations, poor scalability, high investment cost, poor ...
