Connect with other communication chips, responsible for reading programming data and data transmission with the target board; FPGA is responsible for identifying the connection status of the target board, and sending the identification result to the DSP, and controlling the corresponding interface according to the control command issued by the DSP communication; the USB chip is responsible for identifying the connection of the USB device, and sends it to the DSP through the FPGA, responds to the control of the DSP, and reads the data inside the USB device; the 1553B chip is responsible for the communication between the FPGA and the target board; the method includes hardware structure initialization; The USB device is connected to the hardware structure; the target board programming state is initialized; the target board programming and data verification.

Description

technical field [0001] The invention belongs to the technical field of aerospace satellite platforms, and particularly relates to a hardware structure and an application method for on-board rewritable chip programming on the ground, which are used to improve the convenience and high efficiency of on-board equipment data modification, and improve the efficiency of on-board equipment. safety and reliability. Background technique [0002] In recent years, with the continuous development of international aerospace technology, the important data of the control system or use of on-board equipment, such as electronic maps, initialization parameter lists, etc., must be stored in non-volatile memory. [0003] The programming method of the existing on-board device data needs to open the external tooling of the target board, connect the corresponding emulator, and complete the programming operation by opening the compiling software of the PC. For aerospace projects, this method must o...
