DSP local online upgrading method based on Ethernet

The invention discloses a DSP (Digital Signal Processor) local online upgrading method based on Ethernet, which is characterized in that an upper computer of a control end is connected with equipment where a DSP processor is located through a network cable, the DSP processor is externally connected with an EEPROM (Electrically Erasable Programmable Read-Only Memory) and an NAND Flash to serve as a storage medium, the DSP processor runs an Intermediate Boot-Loader program, and a PC (Personal Computer) of the control end stores a file to be burnt and runs the upper computer; the DSP is used for completing hardware initialization by running the Intermediate Boot-Loader program, and waiting for a command and data from a network port; and the upper computer communicates with the DSP processor through the network cable to complete command and data transmission, and the transmitted data is a file needing to be burnt and a position for selecting burning, so that the local online upgrading of the DSP is completed.
