2) Read microcontroller-specific data

3) Flash related configurations like setting up read and write protections for different sectors

4) Flash sector erase

5) Mass erase of the user flash

6) Read and display the protection status of the flash memory

7) Jump to the specified address to execute the code

Along with custom BootLoader development, you will also understand

1) The different memory organization of a microcontroller

2) Memory aliasing and different boot modes of STM32

3) How MCU boots after power-up

4) Vector table mapping and vector table relocation use case of arm cortex mx processor.

5) Difference between In-system programming(ISP) and in-application programming(IAP)

6) Custom boot loader design flow chart

7) Host and Boot loader communication method

8) Implementation of different boot loader commands

You can also extend this BootLoader by giving the following features once you complete the course

1) Encrypt and Decrypt the firmware sent by the host using AES

2) Over-the-air programming by interfacing WIFI or Zigbee Modules
