Abstract

The invention discloses program programming equipment, system and method. The system comprises a storage unit used for storing a to-be-downloaded program; a controller connected with the storage and used for receiving a programming instruction of a user and starting a pre-stored programming step according to the programming instruction, reading the program to be downloaded according to the programming step, and outputting the read program to be downloaded and the combination information of each address code in the address codes of the at least two pre-stored flash memories to be programmed tothe FPGA chip; an FPGA chip connected with the controller and used for obtaining an address of the flash memory to be programmed by adopting a preset decoding operation according to the address code and programming a program to be downloaded to the flash memory corresponding to the address obtained after decoding, a flash memory base connected with the FPGA chip and a power supply which supplies power to the devices. According to the equipment, the program programming of a plurality of flash memories is realized, and the program programming efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a program writing device, system and method. Background technique [0002] Since there is no application program in the Flash chips produced on the production line, each Flash chip needs to be programmed before it can be used. The traditional program burning method is to burn the program into the Flash chip through an emulator or a serial port tool. Such as figure 1 As shown, one end of the J-Link emulator is connected to the PC through the USB interface or a serial port, and the other end of the J-Link emulator is connected to the Flash chip through the JTAG interface. ”) into the Flash chip through the emulator. [0003] However, the inventors have found that the program programming method can only program one Flash chip at a time, so when the number of Flash chips that need to be programmed is large, the programming efficiency will be significantly redu...
