In this embodiment, taking a host end system as a QNX operating system and a client end system as an Android operating system as an example, the dual system upgrading process is as follows: after the QNX operating system at the host machine end is started, mounting processing is carried out on the storage module, and the preset storage partition in the storage module is mounted in the upgrading shared area at the host machine end.
Subsequently, the QNX operating system starts the Android operating system on the client side through the QVM virtual machine of QNX Hypervisor.
And the client side carries out mounting processing on the storage module and mounts the preset storage partition in the storage module into a target storage area of the Android operating system.
At the moment, when the client side detects that the new version is pushed, the upgrading data package is stored in the target storage area, then the sharing instruction is sent to the host side, and if the Android operating system needs to be upgraded, the Android system upgrading package is directly read from the upgrading data package for upgrading.
When the host machine end receives the sharing instruction, the upgrading data packet can be synchronously accessed through the upgrading sharing area path of the QNX operating system, and the QNX system upgrading packet can be upgraded after being read.
In the embodiment of the invention, a disk storage partition is divided in a storage device and is used as a sharable preset storage partition, and the host machine end and the client machine end are used for mounting simultaneously; before a new version is updated and detected, the preset storage partitions are sequentially mounted in an upgrading shared area and a target storage area of a host machine end, when the client machine end detects that the new version is pushed, the upgrading data package is automatically downloaded and stored in the target storage area, the upgrading data package does not need to be downloaded to the storage of the host machine end, the host machine end can directly read the upgrading data package from the upgrading shared area, the disk space of the host machine for storage is saved, and the upgrading efficiency of a dual system (such as a QNX operating system and an Android operating system) is improved.
The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
