Background
In electronic products, a common code upgrading method is IAP, which is In application programming In english, and the IAP upgrading principle is as follows: the code storage medium stores APP Application codes and upgrading processing codes, the English name of the APP is Application, namely Application software, when the APP Application codes identify an upgrading command during running, the APP Application codes skip from an Application code area to an upgrading processing code area to be executed, new codes are written into the Application code area according to the received upgrading command, and after the upgrading is successful, the upgraded codes are reset or powered on next time to be executed.
Since IAPs and application schemes are closely related, communication media and communication protocols of different schemes vary, developers often make different IAP communication media and protocols according to specific application schemes, for example, SD card upgrading can be performed in a scheme supporting SD card, and similarly, upgrading can be performed by wire such as UART, SWD, SPI, and USB, and wireless manners such as Bluetooth and WIFI; IAPs are basically completed by developers themselves, IAP code is usually put together with application code and only one copy is stored, IAP upgrade erases old code APP1, writes new code APP2, no APP runs if power down restarts before writing new code APP2 is completed, that is, IAP upgrade has a risk of failure. This has the following problems: firstly, developers are required to know complicated chip programming flows to perform IAP, and for most software developers, the development of the bottom layer is difficult to understand and debug, and the development difficulty is high; secondly, the IAP code is stored in the user code, the limitations that the IAP process cannot be powered off and the like often exist, the APP code is not operated after the IAP process is powered off, and the risk of IAP upgrading failure exists.
