This video tutorial brings you advanced techniques for dynamic APP loading on microcontrollers with MPU memory protection. By utilizing MPU and SVC, applications can be isolated, ensuring that even if an APP crashes, the system remains unaffected. The dynamic APP loading on microcontrollers is similar to Android applications, allowing programs to be loaded from various sources such as SD cards, NAND, NOR, eMMC, etc., into execution spaces like SRAM, SDRAM, QSPI Flash, and internal Flash.Tencent Video:

This video is divided into the following sections:1. Principle explanation (important core). 2. Accessing kernel and peripheral APIs via SVC software interrupts, entering interrupt mode grants privilege level access for easier API access. 3. After enabling the MPU for dynamic APPs, access to corresponding peripheral addresses is also possible. 4. Handling various exceptions. 5. In the last few minutes, we will demonstrate various debugging and simulation issues between C and assembly files.
