Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] The method, device and system for upgrading embedded device firmware provided by the present invention solve the technical problems existing in the existing network upgrading method for embedded device firmware, and no longer need to upgrade parameters through other additional interfaces (for example, serial ports) There is no need to configure an additional DNS server, and its IP address is fixed, which can meet the application scenarios that require a fixed IP address, and the server does not need to broadcast upgrade parameters in the network, which will not bring additional overhead to th...

The invention belongs to the technical field of embedded devices, and provides a method, device and system for upgrading firmware of an embedded device. The method includes the steps that a server receives an upgrading request broadcast packet sent by the embedded device and judges whether an IP address of the embedded device needs to be modified or not; if yes, the server sends a response packet including the modified IP address of the embedded device to the embedded device; if not, the server sends a response packet including the IP address of the embedded device to the embedded device; the embedded device acquires upgrading files from a TFTP server according to the information in the response packet and conducts upgrading operation. By the aid of the server, a network upgrading parameter is set, the upgrading process is simplified, and user experience is improved. Meanwhile, only a network is used for carrying out communications, other ports are not needed, the ports of the embedded device are saved, moreover, information does not need to be broadcasted all the time in the network, and adverse effects on the network environment can be avoided.
Description
technical field [0001] The invention belongs to the technical field of embedded devices, and in particular relates to a method, a device and a system for upgrading firmware of embedded devices. Background technique [0002] With the increasingly complex functions of embedded devices, the firmware program of embedded devices is also getting larger and larger. The traditional method of using serial ports for firmware upgrades is too slow and the user experience is very poor. Based on this, more and more embedded devices begin to support the network upgrade method. Through the network upgrade, the upgrade speed can be improved, and the connection and other operations required for the serial port upgrade can be avoided, and the firmware upgrade can be performed simply and quickly. [0003] Embedded devices can use the simple file transfer protocol (Trivial File Transfer Protocol, hereinafter referred to as TFTP) for firmware upgrade through the network. TFTP is a protocol in the...
