How to switch the chip on which the program runs？

[tibaiwan2333]

I'm looking to run this program on an ESP32-S3. Could you please advise on what changes I need to make to the project to ensure it works correctly on this chip? Any guidance or suggestions would be greatly appreciated.

Delete (or rename) sdkconfig and rename sdkconfig.s3 to sdkconfig, they are located in the project root directory.
No other changes than creating or selecting an existing board map for the S3 is needed. Board maps made for ESP32 may or may not work, likely pin assignments has to be changed.

I am using Espressif-IDE for development, there I change the target to esp32s3:

I have not compiled for the ESP32-S3 using other IDEs or ESP-IDF yet so I do not know how to change the target MCU for them.

Thank you very much for your assistance, Sir. I have installed IDF 4.3 as suggested by the project documentation; however, I noticed that this installation does not include an IDE. Consequently, I visited the ESP32 official website to install IDF along with an IDE. There, I found that only version 5.1 or higher is available. When I opened my project in the provided IDE and attempted to compile it, I encountered numerous errors. As a result, I am still unable to find a way to flash the firmware onto the ESP32-S3.Could you kindly guide me on how to proceed? I would greatly appreciate any advice or suggestions you could offer to help resolve this issue.

Ask Espressif from where to download v4.3.
I am not yet prepared to fix/reverify against v5 since they are introducing breaking changes with every major release that can be very hard to debug. And debugging ESP32 code is very time consuming.

I do not know if it can help but on my project using idf I use this command on my ci to switch from esp32 to esp32s3:
https://github.com/luc-github/ESP3D-TFT/blob/main/.github/ci/ESP32S3_FREENOVE.sh

idf.py fullclean
idf.py -DIDF_TARGET=esp32s3 reconfigure
idf.py build
