Abstract

The invention discloses a method for chip programming verification, which includes the following steps: S1: the user sets the parameters required for chip programming verification on the programming verification device; S2: detects the programming verification device; S3: The serial number ID of the chip is read, calculated, burned and verified in sequence; S4: read, calculated, burned and verified the file byte data of the chip whose serial number ID has been verified; S5: The chip whose file byte data has been checked is calculated and checked sequentially for the protection bit of the burning status. The communication mode of the present invention is changed from a serial mode to a parallel mode, adopting a multi-channel separate comparison mode of verifying and verifying while programming, timely discovering abnormal links in programming, and judging abnormal channels in time to improve programming Verify the overall test efficiency, effectively identify the power-on status of the channel, prevent the channel from being inserted in reverse, and effectively avoid quality accidents caused by board removal errors.

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 ...
