Embodiment
[0027] The embodiment of the present invention solves the software upgrade method for upgrade failure caused by insufficient disk space, including the following steps:
[0028] Step 1. Use the split command tool under the linux operating system to cut the prepared upgrade file into multiple small files, and number the cut small files at the same time. Among them, the upgrade offset address of the first small file is 0;
[0029] Step 2. Package and compress the cut multiple small files as a whole to generate the final upgrade package;
[0030] Step 3, extract the first small file in the upgrade package, preferably, use the extract command tool to extract the divided small file;
[0031] Step 4. Use the extracted small file to upgrade according to the offset address of the currently upgraded small file. Preferably, use the extracted small file to upgrade using the dd command tool;
[0032] Step 5. Record the size of this small file and add it to the previously upgraded offset ...
