AI Technical Summary
Traditional online upgrade methods lack the ability to verify the validity of upgrade files, which can cause processor programs to malfunction under abnormal conditions, affecting the use of device terminals.
When the bootloader starts, it reads the current values of the upgrade flag, the send completion flag, and the storage area flag in the flag storage area, determines whether the preset conditions are met based on these values, retrieves the executable file from the corresponding program backup area, sends it to the program execution area, and updates the current values of the flags to ensure the reliability of the upgrade process.
Even if program problems or power outages occur during the upgrade process, the normal operation of the device to be upgraded can still be guaranteed, improving the reliability of the upgrade process and the stability of the device.
