Embodiment Construction

[0025] A method for setting IP and MAC addresses based on an embedded system platform, comprising the following steps:

[0026] 1] Select a free sector from the non-volatile memory of the target computer;

[0027] 2] Write the IP address and MAC address in the selected free sector;

[0028] 3) Modify the interface function for obtaining the address in the driver layer of the target machine, and generate the modified code;

[0029] The function of the modified interface function is: the CPU of the target machine reads the IP address and the MAC address from the free sector;

[0030] 4) Compile and connect the modified code to generate the driver target code and solidify it in the non-volatile storage area;

[0031] 5) Power on the target machine, set the IP address and MAC address of the network card:

[0032] 5.1] The target CPU reads and writes the IP address and MAC address from the free sector;

[0033] 5.2] The target machine writes the IP address and MAC address read ...

Abstract

The invention discloses a method for setting IP (Internet Protocol) and MAC (Media Access Control) addresses based on an embedded system platform. The method comprises the steps of: a) selecting an idle sector from a nonvolatile memory of a target machine; s) writing an IP address and an MAC address from the selected idle sector; 3) modifying an interface function for acquiring the address in the driving layer of the target machine, and the function of the modified interface function is that the CPU (Central Processing Unit) of the target machine reads the IP address and the MAC address from the idle sector; 4) generating a target code by compiling and connecting modified codes and curing the target code in the nonvolatile memory; and 5) electrifying the target machine, initializing a network card and finishing the address set. According to the method, the technical problem that an existing method for setting the IP and MAC addresses can waste time and influence the life of large areas of the nonvolatile memory, the IP and MAC addresses of the network card of the target machine can be quickly modified, a mass of debug time can be saved, and the life of the nonvolatile memory of the target machine can be prolonged.

Description

technical field [0001] The invention belongs to the field of embedded driver software development, in particular to an IP and MAC address setting method based on an embedded system platform. Background technique [0002] In embedded system development, most target machines will be configured with network functions. Among them, when configuring the network function, you need to set the IP and MAC address of the network card. In the current embedded operating system platforms such as VxWorks, Tianmai, etc., the IP and MAC address configuration of the network card is configured in the static configuration file, and then the entire driver program (some include the entire OS layer) is built and the binary file is solidified The IP and MAC address of the network card of the target machine can only be set in the non-volatile memory of the target machine (such as figure 1 shown). However, it is often necessary to modify the IP address or MAC address of the network card of the tar...
