Embodiment Construction
[0086] In order to solve the deficiencies of the prior art, the embodiment of the present invention proposes a method, device and system for wireless communication module software autonomous over-the-air upgrade.
[0087] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0088] In order to enable the sub-modules in the wireless communication module to have independent upgrade functions, it is necessary to re-plan the data organization of the wireless communication module, such as figure 1 shown, including:
[0089] Step S101: Modify the scatter-loading file, use the "fixed address" attribute to fix the link address of each submodule at a preset address, that is, fix the first address (base address) of each submodule;
[0090] After fixing the first address of each sub-module, in the compiled image file, each sub-module will be linked and programmed to a fixed location. Preferably, free space requ...
