The invention belongs to the technical field of aircraft guidance and control and discloses a method capable of realizing the operation of curing and guiding software and application software based on a real-time MCU (Micro-programmed Control Unit) of a TMS320F28335 chip. The method comprises the following steps: step 1, performing the address planning and allocation of the guiding and curing software and the application software in FLASH; step 2, operating the guiding and curing software when MCU start is set; step 3, judging whether FLASH programming is required to be performed or not by utilizing the guiding and curing software to update the application software. The demands on the online upgrade and the guiding of the application software by using TMS320F28335 as a system of the MCU are satisfied; the system disassembly is not required when the software is upgraded, so that the software upgrade ability and the equipment reliability are improved, and the maintenance processes are simplified.
Description
technical field [0001] The invention belongs to the technical field of aircraft guidance and control, and relates to a method based on a real-time MCU (microprocessor) of a TMS320F28335 chip, which can realize solidification and guide the operation of application software. technical background [0002] TMS320F28335 is a 32-bit floating-point digital signal processor with powerful control and signal processing capabilities from TI. The 16-bit boot ROM has the advantages of high precision, low cost, low power consumption, high peripheral integration, large data and program storage, and can be widely used in control and communication fields. At present, the degree of informatization of weapon systems is getting higher and higher. In order to ensure the reliability, stability and efficiency of combat systems, the corresponding research and development models are also constantly changing to modularization, componentization, and serialization. With high computing and processing c...
