s20: splitting the mirror image package to generate a plurality of image files corresponding to each device;
s30: assembling the required image files according to the chip types selected by the user to form an upgrade package meeting the upgrade requirement;
s40: sending the upgrade package to a multicast group in a local area network;
s50: and after receiving the upgrade package, writing the upgrade package into equipment and finishing upgrading.
The embodiment is matched with a unified multicast upgrading platform, after a multicast environment is established, a user selects a mirror image package to be upgraded, the mirror image package is a unified version upgrading package and contains image files of different devices, the image files are uboot files, kernel files, rootfs files and/or intelligent frames and the like, and the embedded chip BOOT software and the windows/linux UI application software are involved.
Wherein, step 20 specifically includes:
and splitting the mirror image package according to the types of the chips, for example, different types of chips have different lengths of the corresponding image files, and further generate a plurality of image files corresponding to each device.
Step 30 specifically comprises:
and assembling the image files according to the chip type selected by the user to form an upgrade package meeting the upgrade requirement. For example, the user selects to upgrade the equipment of the MTK chip, and at this time, the system assembles the image files corresponding to the MTK chip in sequence to form an upgrade package meeting the upgrade requirement of the equipment containing the MTK chip.
Step 40 specifically comprises:
