Hello everyone, I am using STM32F070RB with SIM808 on board. I just want to have FOTA feature in my design so that program can be updated remotely via GPRS. The current program size is of 67KB (i.e., 61KB internal program memory is remaining) and 8MB external EEPROM is also available on the board. Can anyone guide me how to do it?

Not exactly. There is likely much documentation to read and understand if you wish to do it yourself.

Review how you want to provide the update, ie HTTP or FTP server, etc.

Review how you want to manage and download the data while not losing all the firmware in the part. You might need to implement a small loader of your own.

Review IAP examples (In-Application Programming)

Review Flash Erase and Writing processes.
