About the Project

The project aims at enabling firmware update of STM32Fxx and STM32Gxx series MCUs Over-the-Air using ESP32.

Testing was done with ESP32-DevKitC v4 board and STM32F103C8T6 (Blue Pill), STM32F072C8T6 and STM32G431KB (NUCLEO-G431KB). You can try with any other STM32Fxx/STM32Gxx MCUs and let us know how it worked out.

Code

/esp_stm_flash -> Basic flashing utility, requires path of the .bin file which has been already uploaded in SPIFFS

/file_serving_stm -> OTA demo, with HTTP File Server with embedded flash link

/references -> Python scripts for understanding the flashing protocol commands and verification

Getting Started

Hardware Required

To run the OTA demo, you need an ESP32 dev board (e.g. ESP32-WROVER Kit) or ESP32 core board (e.g. ESP32-DevKitC). For the STM32, you can use the STM32 Blue Pill.

Prerequisites

ESP-IDF v4.0 and above

You can visit the ESP-IDF Programmming Guide for the installation steps.
Arduino IDE

Arduino IDE provides with an easy way to generate the .bin files for your STM32 MCU. For setting up Arduino Core for the STM32 family, you can follow this link.

You can also use CubeIDE or Keil for generation of .bin files.

Setting Up

Wire your STM32 (e.g. Blue Pill) to the ESP32 as follows:

ESP32 STM32

GPIO4(TX) PA10(RX)

GPIO5(RX) PA9(TX)

GPIO19 RESET

GND GND
Generate a .bin file for the STM32 MCU code you want to flash.

ESP32	STM32
GPIO4(TX)	PA10(RX)
GPIO5(RX)	PA9(TX)
GPIO19	RESET
GND	GND

Disclaimer

We have assumed that the STM32 is already in boot mode before flashing the code (Step 1 & 5 in Usage section). You can use a MOSFET as a switch to automate the process, using an ESP32 GPIO as an input.

The program code uses only the path of the binary file to be flashed as a parameter. Thus, it can be easily integrated into any other projects as the file can be sent to ESP32 over any protocol (MQTT, HTTP Client, WebSockets).

Read carefully the Boot Mode Procedure (AN2606) and the USART protocol used in Bootloader Mode (AN3105) in order to deeply understand how to use this project with other STM32 microcontrollers.

Usage (For STM32 Blue Pill)

Make sure the BOOT0 jumper pin on the board is set to 1 (programming mode) while uploading the code. Once the code is flashed this pin can be changed back to initial position (operating mode). This procedure with your STM32Fxx MCU varies according with your MCU version.

Refer this documentation for help.

Open the project configuration menu (idf.py menuconfig) go to Example Connection Configuration ->
1. WiFi SSID: WiFi network to which your PC is also connected to.
2. WiFi Password: WiFi password

In order to test the OTA demo -> /file_serving_stm :
1. Compile and burn the firmware idf.py -p PORT -b BAUD flash
2. Run idf.py -p PORT monitor and note down the IP assigned to your ESP module. The default port is 80.
3. Test the example interactively on a web browser (assuming IP is 192.168.43.82):
  - Open path http://192.168.43.82/ to see an HTML web page with list of files on the server (initially empty)
  - Use the file upload form on the webpage to select and upload a .bin file to the server
  - Click a file link to download / open the file on browser (if supported)
  - Click the delete link visible next to each file entry to delete them
  - Click on the flash link to flash the .bin code file uploaded to the connected STM32.

After clicking the flash link, you should get the following results -

Revert the BOOT0 pin to its initial position and press the RESET Button on the STM32.
Voila! your STM32 is now running the code you uploaded Over-the-Air!

Compatibility

According to STM documentation, this project could be compatible with a wide range of microcontrollers, prior to some customization:

STM32F0 Series (verified)
STM32F1 Series (verified)
STM32F2 Series
STM32F3 Series
STM32F4 Series
STM32F7 Series
STM32G0 Series
STM32G4 Series (verified)
STM32H7 Series
STM32L0 Series
STM32L1 Series
STM32L4 Series
STM32L5 Series
STM32U5 Series
STM32WB Series
STM32WL Series

Troubleshooting

Check your wiring. Make sure that the ESP32 and STM32 are powered separately. Don't power one MCU using the other.
Verify your WiFi SSID and password.
Check if your STM32 is locked using this official tool by STMicroelectronics and unlock it by erasing the memory of your chip.
Check your STM32 code, which generated the .bin file, for any 'logical' errors.
For any other bugs or errors, you can always raise issues.

Flashing with DFU

A project I'm running builds to a DFU file instead of a .bin file. It's crashing before I can even upload the file. Is it possible to flash this? When I attempt to upload the 110KB DFU file it returns

I (18706) FILE_SERVER_HTTP: Found file : Blink.ino.bin (13492 bytes)
E (24596) FILE_SERVER_HTTP: Failed to create file : /spiffs/myproject.ino.dfu

How to build and flash using esp-idf command prompt

Hi I have been using ESP-IDF command prompt and couldn't build and flash the code. can you explain or give some steps to upload. I am new to esp-idf

For OTA updates for AVR MCUs, you can follow this project: ESP-LINK (ESP8266 it's cheaper)

The esp-link firmware connects a micro-controller to the internet using an ESP8266 Wifi module. It implements a number of features:

transparent bridge between Wifi and serial, useful for debugging or inputting into a uC
flash-programming attached Arduino/AVR microcontrollers and LPC800-series and other ARM microcontrollers via Wifi
built-in stk500v1 programmer for AVR uC's: program using HTTP upload of hex file
outbound REST HTTP requests from the attached micro-controller to the internet
MQTT client pub/sub from the attached micro-controller to the internet
serve custom web pages containing data that is dynamically pulled from the attached uC and that contain buttons and fields that are transmitted to the attached uC (feature not fully ready yet)

Header fields are too long for server to interpret

cannot flash and delete. show "Header fields are too long for server to interpret"

ESP32 can't using other Serial?

Can't I use other serial ports? Do I have to use the main serial port? I use ESP32, I can use Serial, but I can't use Serial2

Firmware Update Over The Air (FOTA) for ECU (STM32) via ESP32 (HTTP - CAN protocols)

I found this other option which uses CAN bus instead of serial port:

https://github.com/nhatuan84/Firmware-Update-Over-The-Air-FOTA-for-ECU-STM32-via-ESP32-

Thanks for your sharing

It's a pretty good project.
While, I must recovery jumper cap of Boot pins and put down the reset button to ensure the program downloaded in MCU to restart.
In orther word, through ESP32 can flash the MCU wirelessly, we have to recover the wiring and reset it offline .

Serial Timeout ERROR

Hi for all, I am trying to use this example, but I couldnt it successfully. I got Serial timeout error.( esp32 and stm32 could not talk successfully. ) I have tried everything, powered up stm32 and esp32 with different sources, erased stm32 flash memory with STMFlashLoader, changed up baudrate, or buttons and still got error. What could be the reason of this?
Thank you...

Replacing UART by RS485

Hello,

We have 2 boards, one ESP32 and one STM32. They are communicating by RS485 over UART with at each side one RS485 transceiver.
Do you think it's possible to download the STM32 firmware by RS485 ?

Thank you.

running the project in vscode

Hello! thanks for the project. How to compile it in vscode if we have here two directories esp_stm_flash and file_serving_stm and each of them has its own main file?

How can we make this work with STM32H7 baords ?

Hi @laukik-hase , I am trying to do the same thing but for STM32H750 boards. Can you tell me about where to start and the things that I need to take care of ?

I am ready to contribute to this repo about it.

Regards.

control BOOT0 pin from ESP

By adding an additional pin, controlling BOOT0, the whole programming operation can be automated without human intevention

Port to B-L475E-IOT01A

Hi!
Can this code be directly run on B-L475E-IOT01A board provided by STM32?

flash ESP32 instead of STM32 after uploading the file to the file server

Hello! I downloaded the project about flashing ESP instead of STM32 through a file server on the link https://github.com/versamodule/ESP32-OTA-Webserver but I face some problems:

-I can't open menuconfig so as to set the SSID and password;
-When I try to build I get the error Unknown CMake command "register_component" . When I comment this line in CMakeLists.txt , the compilation is done but the flashin is not possible(command flash from idf.py not found).

fatal error: driver/uart.h: No such file or directory

Hello! I am trying to test the file_serving_stm project but I can´t manage to make it compile.
It throws the following error:
fatal error: driver/uart.h: No such file or directory

It would be really helpful if someone can help me to solutionate this.
Thanks! real

Compatibility with F407

I want to flash my STM32F407 discovery board, but I can't quite get it to work
I've tried it on a F103 (bluepill) and it worked fine.

Everything looks great, but after trying to erase memory, I get a sync failure.

Have you tried it with an F4? Any idea on what I should test/debug? I've tried reducing the baud rate to 9600bps, which didn't help.

Here's are the packets during the attempted flash:
