Problems solved by technology

Due to the low rate of the computer's general interface, it takes a long time to program the Flash chip through system programming; the existing programming equipment only supports single-channel programming, and the programming efficiency is low, which cannot meet the needs of single-board The need for batch programming of Flash chips during production and maintenance
In addition, most programming devices rely heavily on single-board CPUs, and only support programming through specific types of single-board CPUs.

Abstract

Embodiments of the invention disclose a programming method for a flash memory chip, and an apparatus thereof. The method comprises the following steps that: a programming device acquires programming data, and converts the programming data into a joint test action group (JTAG) timing signal, wherein the programming device is provided with a plurality of JTAG interfaces, and is connected with a plurality of target plates through a plurality of the JTAG interfaces; programming operations are performed for flash chips in a plurality of the target plates by the programming device according to the JTAG timing signal. According to the embodiments of the invention, the programming operations can be simultaneously performed for a plurality of the flash chips, and the apparatus can be adapted to the requirement of batch programming.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a flash memory chip programming method and device. Background technique [0002] At present, methods for programming a Flash (flash memory) chip mainly include programming through a programmer, programming using an on-board programmer, and system programming. Among them, programming through the programmer and programming with the on-board programmer need to add additional equipment (for example, test points or isolation chips) in the single-board design to assist external equipment to realize the programming of the Flash chip. The above-mentioned additional equipment needs to occupy Board area, as the density of chips on a single board increases, the above defects become more and more obvious. [0003] System programming is realized based on JTAG (Joint Test Action Group, joint test action group) technology. Generally, programming equipment is used to convert the output da...
