What should I do with my boot loader?
A common thing to do with a bootloader is monitor stability. This can be done with a relatively simple setup: If the counter gets to 3, the bootloader does not start the app but instead signals an error. This requires shared, persistent data between the application and the bootloader which is retained across reboots.
How to write a bootloader from zero to main?
To start, our bootloader must do two things: We’ll need to decide on a memory map, write some bootloader code, and update our application to make it bootload-able. For this example, we’ll be using the same setup as we did in our previous Zero to Main posts:
What can you do with a microcontroller bootloader?
1) It can do the in application programming (IAP). You can use the BootLoader to flash a given application binary 3) Flash related configurations like setting up read and write protections for different sectors 4) Vector table mapping and vector table relocation use case of arm cortex mx processor.
How to write a bootloader from a startup file?
Previously, we wrote a startup file to bootstrap our C environment, and a linker script to get the right data at the right addresses. These two will allow us to write a monolithic firmware which we can load and run on our microcontrollers. In practice, this is not how most firmware is structured.
