Hi, I just tested quickly.. AtomS3 is OK; the project can be created and compiled.

[env:m5stack-atoms3]
platform = espressif32
board = m5stack-atoms3
framework = espidf

Hi Felix,

Thank your for your help. The most important is to hear that your system is working. I should have a Linux based development environment too.. I will make it.

Hi Felix,

I am not sure if everything is OK but I reinstalled esp-idf framework again.

It works with some other Esp32-S3 boards.

This is my platformio.ini:

[env:m5stack-stamps3]
platform = espressif32
board = m5stack-stamps3
framework = espidf

And here some messages when trying to compile:

• list itemExecuting task: C:\Users\XXX.platformio\penv\Scripts\platformio.exe run --environment m5stack-stamps3

Processing m5stack-stamps3 (platform: espressif32; board: m5stack-stamps3; framework: espidf)
Error: Unknown board ID 'm5stack-stamps3'

• The terminal process "C:\Users\XXX.platformio\penv\Scripts\platformio.exe 'run', '--environment', 'm5stack-stamps3'" terminated with exit code: 1.

• list itemTerminal will be reused by tasks, press any key to close it.

Hi, I try to make a new esp-idf project for Stamp S3. But it comes the following error:
