Problems solved by technology
[0003] This kind of partition scheme with backup partition will cause a certain waste of space, especially when the flash space is relatively small, the use of flash will become very tense
In some projects that reduce the flash capacity, there is barely enough space after optimizing the space occupation and code; the current space is not sufficient, and new functions cannot be added, resulting in a decline in product competitiveness. Therefore, under the current situation, it is urgent to upgrade the existing The upgrade plan is optimized to provide reserved space for new product features in the future

The invention provides a fota upgrading method for reducing the number of backup partitions, and relates to the technical field of firmware upgrading, and the method comprises the following steps: S1, making an upgrading file package, storing modem file content behind a header, and placing the upgrading file package on a fota server to form a fota package; s2, the mifi device downloads and processes a packet header, and obtains a fota packet from a fota server; s3, downloading the content of the modem file in the fota packet into the system backup partition; s4, the mifi equipment verifies whether the content of the modem file in the system backup partition is complete or not, if yes, the content of the modem file in the system backup partition is copied into the modem main partition, and the step S5 is executed; s5, temporarily storing the content of the boot file and the content of the system file in the fota packet, and restarting the mifi equipment; s6, in the restarting process of the mifi equipment, the LK bootstrap program copies the boot file content in the boot backup partition and the system file content in the system backup partition into the corresponding main partition, and upgrading is completed.
Description
technical field [0001] The invention relates to the technical field of firmware upgrades, in particular, the invention relates to a fota upgrade method for reducing the number of backup partitions. Background technique [0002] The existing upgrade method needs to store one image file in the main partition and the backup partition, and the current flash layout needs to store three image files in six partitions. Flash is a storage device for storing Linux operating system image files (aboot), modem image files (modem), and root file system (system) image files. Its storage space is divided into 6 partitions: aboot main partition, aboot backup partition, modem master partition, modem backup partition, system primary partition, and system backup partition. The aboot primary partition and aboot backup partition store the aboot image, the modem primary partition and the modem backup partition store the modem image, and the system primary partition and system backup partition stor...
