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

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

W (24826) httpd_txrx: httpd_resp_send_err: 500 Internal Server Error - Failed to create file
W (24836) httpd_uri: httpd_uri: uri handler execution failed

and on the webpage it shows

Server closed the connection abruptly!

Hey, I am able to successfully upload the code on the local server but when I am pressing the flash button the web page breaks and I see this error (I (1540683) FILE_SERVER_HTTP: Found file : I2C_RTC.bin (11668 bytes)

I (1542813) FILE_SERVER_HTTP: File sending complete
W (1548003) httpd_parse: parse_block: request URI/header too long
) when I monitor the COM port . I just built and flashed the file_serving_stm folder and flashed it, is it correct?

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.

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

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:

Thanks!!

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.

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

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

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

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?

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)

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).

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 .

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...

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

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
