How to upgrade firmware in STM32?

Question

Heelo all,

I think it might be silly question.

I am using STM32F2XXX series of controller. I want to upgrade my firmware. My new firmware will be stored in RAM of the controller.

So if i want to use this new firmware and upgrade the firmware of the device, What are the changes i need to do in bootloader code?

Thanks

Please take a look at this application note . BUT be warned: the F2 series has flash sizes ranging from 128KB to 1MB but the internal RAM is only 128KB so you'll need to implement a offsite storage location for you program. Because it won't fit inside your RAM.
