Hello,
I have tested 3 ESP32 boards:

ESP32-DevKitC(ESP32-WROOM-32E) --- Compile to Target success!
ESP32-S3-DevKitC-1 v1.0 --- Compile to Target success!
ESP32-C3-DevKitC-02 v1.1 --- Compile to Target failure...

Hi Dequiang!

Please have a look here and go to almost the of the tread and see what Martin, medelec write.

Look like there are an issue with IDF 5.3

Hi Jorgen,

Thank you for your fast reply.
I have checked the Espressif website, the lastest ESP-IDF version is v5.5, is it help to upgrade to v5.5 from v5.3.1 ?
If it may works, how to upgrade, just download the ESP-IDF Windows Installer and directly install it?


Or better move to ESP-S3

Thanks

Hi again!

I don`t know if the 5.5 is better? I switched to the ESP32 S3 model. I also don`t know how to upgrade to 5.5 because my 5.3 was installed via ESP toolchain, but the S model work fine by me.

Nice weekend

Agree！Better don't bother it
I have already ordered the new ESP32 S3 board today

Thanks and have a nice weekend!

Warm greetings to everyone from Istanbul. I hope you're all doing well.

Can someone please explain how we can change the ESP-IDF version to 5.1 or 5.5?

The current export.bat file is configured to call only version 5.3. It seems that Espressif has customized this setup specifically for the Flowcode ecosystem.

However, we need a tool or method that allows us to select different ESP-IDF versions, such as for the ESP32-C3 or other ESP32 series.

If someone can clearly explain how to do this, I’d be happy to apply and implement it for you.

I posted a batch file at viewtopic.php?t=2966&hilit=esp32+batch that allows this....

I use this regularly - and it creates a new directory for each project (this allows me to use the espressif components such as lvgl or camera) The only issue is that the serial port is hard coded (I use COM6) but you might need to alter this - and I need to use compile to hex (not compile to target) - on the plus side I have 4 espressif frameworks installed and to swap I use the install.bat in the framework to choose between them....

Note that if you do switch version - you will need to do idf.py fullclean on the relevant project directory.
