IAP over UART

[TFern]

Hello all,

I know this has been probably done to death,but Just a quick link or some pointer if possible :

I am using an ESP8266 to flash code to an STM32F103 over the UART.Basically I want to do what the "Flash Loader Demo" STM utlity does, by using the ESP8266 as a host.

I did read the appnotes and do some preliminary trials with a terminal program. But just to avoid reinventing the wheel ; has anyone seen any working C code which I could port to the ESP8266.

TIA

Thomas

Have a look at  https://git.code.sf.net/p/stm32flash/code. It is code to talk th the builtin STM32 serial bootloader. The setup is for running the code on a PC, but probably much of the code is reusable.
