running the project in vscode

[Benedito821]

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?

Hello, @Benedito821. Glad to see the project helped you.

Both the directories are different examples, you can build individually them according to your purpose. Refer this section for more info.

I am facing a very annoying problem now: the compiler can't find the file stm_flash.h although it is in the folder components. I tried to add the path in .json file but nothing actually changed. Do you have any suggestions on how to solve this?

can I use this project to flash not stm but esp itself(if don't switch the jumper)?

how could I solve this issue ?
E (5613) SPIFFS: spiffs partition could not be found
E (5613) : stm_pro_mode (initSPIFFS:45) Failed to find SPIFFS partition

Hello, @Benedito821
You cannot use this project to flash an ESP32 using another. You can take a look at this project for more information and play with it according to your use case.

Regarding the SPIFFS issue, can you run this example and check if you get the same problem? Also, check your flash size and modify the partition table accordingly. (I had a 4MB flash model, you might have a 2MB one).

thanks for your reply! I meant not one esp flashing another, but flashing that esp that was supposed to program the stm(the esp itself) as I have only one esp.

[Benedito821]

I runned the SPIFFS example and it worked as expected.Could you please give a hint on how to modify my partition table? I found an article Partition tables of esp but I just named my csv file and I don't know what to do further.
Here is my partition table:

Name, Type, SubType, Offset, Size, Flags
nvs,data,nvs,0x9000,24K,
phy_init,data,phy,0xf000,4K,
factory,app,factory,0x10000,1M,

Hello, @Benedito821
Here is the csv from the example. Reduce the SPIFFS partition size if you have 2MB flash. Check this out for finding that.

[Benedito821]

Everything has worked but one: the flash failed(probably because I didin't connect a stm32 board). So, could you please respond this quaestion, once it is probably the reason of the error? Thanks for the help so far!

Hello, @Benedito821

You can flash the ESP using OTA. There are examples in ESP-IDF and also many applications from other users.

[Benedito821]

I honestly saw the esp OTA example. But the problem is that it doesn't have a file server as in your project, so the bin file upload is a bit awkward. Do you know an OTA example that has a file server?

[laukik-hase]

Hello, @Benedito821
What are you looking for exactly? Do you want to flash ESP32 instead of STM32 after uploading the file to the file server?

[Benedito821]

Yes!!!

Hello, @Benedito821
Is this similar to what you are looking for: https://github.com/versamodule/ESP32-OTA-Webserver

I am closing this issue now, if you face any other problems with our project, please feel free to raise another issue.
