The invention discloses a method and a device for generating a software version of embedded equipment, and belongs to the field of software versions. The method comprises the steps of receiving a software version generation instruction, wherein the software version generation instruction comprises an identifier of at least one to-be-generated software platform object; software platforms corresponding to different software platform objects depend on different software version generation environments. The software platform object comprises a generation rule file and a plurality of software modules, the generation rule file is used for describing a software version generation rule of a corresponding software platform, and different software modules in the same software platform object correspond to different application services of the software platform to which the different software modules belong; in response to the software version generation instruction, a to-be-generated software platform object is determined from a plurality of stored software platform objects; and a software version package is generated based on the determined generation rule file of the to-be-generated software platform object and the corresponding software module, the software version package comprising software versions of software platforms corresponding to the to-be-generated software platform objects.
