And step 9: the Internet of things equipment starts a restarting process through an internal mechanism.
Step 10: after the program is started, the program enters a Boot loader code segment, and the program detects whether the configuration area has a special upgrading mark.
And step 11.1, if the mark is not present, the step S7 indicates that the power-off or the application program which is not to be upgraded exists, and the program jumps to the original version to continue running.
And step 11.2, if the mark exists, calculating the check sum of the upgrading code area.
And 12, comparing the checksum of the upgrade code area obtained by calculation with the checksum recorded in the configuration area.
Step 13.1, if the version is inconsistent with the original version, the application program jumps to the original version to continue running;
and step 13.2, if the upgrade contents are consistent, copying the upgrade contents of the upgrade code area to the APP code area.
And 14, after the copying is finished, comparing whether the contents of the upgrade code area and the APP area are consistent or not again:
step 14.1, if the two are not consistent, jumping to step S13.2;
and 14.2, erasing the special mark, the checksum length and the application program of the upgrading of the configuration area, and restarting the application program through an internal mechanism.
