STM32 Bootloader: What is Bootloader, how to use it & what are all the concepts we need to know to implement bootloader in STM32L4R5ZI MCU?

[Shilpashree Madhu]

Why we need Bootloader, what is the tool to implement this, How to interface it, what are the Security features available in Bootloader?

It depends on which bootloader you are talking about: you can use the internal bootloader, which is discussed in detail in AN2606, or you can use your own, self-written one.

Difference:

• the internal one is in parallel to the user flash, so it does not take up any space for the user application
• a self-written one offers full flexibility, but reduces the usable user Flash

Please read the documentation in AN2606 mentioned above as it probably answers a lot of your questions.
