Hi,
I am using STM32, and the firmware is updating to a separate flash bank during upgrade. So, there is no issue and the application can still be run from its own flash. Yes, i see most of the available example are using TFTP with bootloader. However, i see product use web-browser for firmware upgrade. I was wondering what is the underlying mechanism to do it. Since ST application example come with a webserver using lwIP, i wish to know how an upgrade file can be transfer part over to the MCU, program and instruct it to transfer another portion and repeat till complete.
Thanks!
Tom
