Abstract

The invention relates to the technical field of OpenCPU software. The embodiment of the invention provides a software upgrading method, device and equipment based on an OpenCPU. The software upgrading method based on the OpenCPU comprises the steps of acquiring a source file comprising an upgrading program source code; declaring all system functions needing to be called in the source file as an extern type to obtain a new source file; compiling the new source file to generate an intermediate file, wherein a plurality of relocatable compiling parameters are adopted in the compiling process; adding a function library required by operation to the intermediate file, and generating an upgrading file through a link; and upgrading by adopting the upgrading file. According to the embodiment, the upgrading efficiency and the upgrading stability can be improved.

Description

technical field

[0001] The present invention relates to the technical field of OpenCPU software, in particular to an OpenCPU-based software upgrade method, an OpenCPU-based software upgrade device and an OpenCPU-based software upgrade device. Background technique

[0002] OpenCPU is an embedded development solution. In the application of (NB-iot / 4g / 5g and other LTE) modules, it is no longer necessary to connect an external MCU as the main control, but to use the module as the main control, which saves a lot of hardware costs and simplifies the design of the solution .

[0003] In the current OpenCPU solution, the OS mostly uses freeRTOS, LiteOS, etc., which do not support dynamic module loading. Manufacturers provide sdk in the form of libraries. Based on these libraries, users add their own application codes, compile and package them into a complete image, and then update to modules through tools or OTA methods. This upgrade method is inefficient and error-prone. [000...
