Comprehensive Official Resources on STM32 IAP

ISP uses communication interfaces for programming, and the boot code is written by the manufacturer and cannot be changed.

Comprehensive Official Resources on STM32 IAP

IAP (In-Application Programming) refers to the ability of an MCU to obtain new code and reprogram itself, allowing a program to change the program. In application programming (IAP), the user’s application code erases/programs the internal Flash memory. A typical application of this method is to use a small piece of code to implement program downloading. In fact, the ISP function of the microcontroller is realized through IAP technology, meaning that a small boot program is already embedded in the chip before it leaves the factory. When powered on, the chip starts running this program. When it detects a download request from the host computer, it communicates with the host and downloads data to the data storage area, thus enabling firmware upgrades.
