Description

technical field [0001] The invention relates to the technical field of optical communication equipment production, in particular to a flash memory programming system and method in the production of optical communication equipment. Background technique [0002] At present, all the ARM (Advanced RISC Machines) chip application software programs FLASH (flash memory) programming of optical communication manufacturers are carried out by PC and emulation downloader (such as JLINK emulation downloader). The specific method is to insert JTAG ( Joint Test Action Group, Joint Test Working Group) cable port, combined with software tools (such as J-FLASH ARM software tools) for program programming of flash memory. [0003] However, due to the large demand for PCs and emulation downloaders in the traditional programming process, the cost is high; and when the ARM chip application program is upgraded, it is necessary to manually plug and unplug the emulation downloader repeatedly, which s...
