The invention discloses an embedded device software online upgrading method based on storage resource reallocation. The method comprises the steps that firstly, the current condition of embedded device storage resources is obtained, a transition mirror image is manufactured, partition information of the transition mirror image is consistent with current partitioninformation of the embedded devicestorage resources, and an extra virtualpartition is further include; then, the transition mirror image is upgraded into the embedded device, and the embedded device is restarted to enter a new system;then, a final mirror image is manufactured, the size of the final mirror image is consistent with that of the embedded device storage resources, and the partition information of the final mirror image is consistent with the partition information reallocated by the embedded device storage resources; finally, the final mirror image is upgraded into the novel system of the embedded device and restarted, and the upgrading method specifically comprises the step of erasing the whole final mirror image into the virtualpartition of the novel system of the embedded device. According to the online upgrading method, the storage resources can be reallocated, the embedded device upgrading period is prolonged, and the use cost of a user is lowered.
Description
technical field [0001] The invention belongs to the technical field of embedded development, and more specifically relates to an online upgrading method of embedded device software based on redistribution of storage resources. Background technique [0002] With the rapid development and progress of technology, embedded devices are becoming more and more popular, and software updates are also getting faster and faster. Currently, there are two types of software upgrade methods, one is online upgrade, and the other is offline upgrade. The offline upgrade method is generally implemented through manual operations, and is only used for R&D experiments or small-batch embedded device software upgrades. The online upgrade method is generally realized through automatic operation, and a large amount of software upgrades can be performed on online embedded devices through a server. The location of the storage area where the software is updated each time is different, which will lead ...
