Different heap consumption

[Blueforcer]

If i compile my ESP32 firmware with VS-Code/platformIO on windows 11, the ESP reports a free heap of 135kb. As soon my github action compiles the same code, the ESP reports only 95kb left. Why i have 30kb less, with the same code?

      - name: Install PlatformIO
        run: |
          python -m pip install --upgrade pip
          pip install --upgrade platformio
          pio run --environment ulanzi

---

Configuration

platformIO core on both: 6.1.10

Operating system:

Windows 11 (VSCode), ubuntu-latest (GithubAction)

Description of problem

Steps to Reproduce

1. compile a firmware in VSCode under windows 11
2. compile a firmware via github action
3. compare the ESP.getFreeHeap(); output

Expected Results

Both should be the same

Different platform version? What does the Github CI log have to say about "Platform: Espressif32" version vs what's shown on your computer?

Both are the same platformIO core (6.1.10)

I see the package verisons are a bit differnet

Github:

• framework-arduinoespressif32 @ 3.20011.230801 (2.0.11)
• tool-esptoolpy @ 1.40501.0 (4.5.1)

• toolchain-xtensa-esp32 @ 8.4.0+2021r2-patch5

  Vscode:

• framework-arduinoespressif32 @ 3.20007.0 (2.0.7)
• tool-esptoolpy @ 1.40500.0 (4.5.0)

• toolchain-xtensa-esp32 @ 8.4.0+2021r2-patch5

  Maybe i should force platfromIO in the ini to use arduinoespressif32 2.0.7?

@maxgerhardt , thanks for the hint!

@Blueforcer , see https://github.com/platformio/platform-espressif32/releases

You can use the fixed version in platformio.ini. See https://docs.platformio.org/en/latest/projectconf/sections/env/options/platform/platform.html
