Failing to connect ESP32S3 to MATLAB

Postby Jim_Stuart » Sat Aug 17, 2024 1:52 am

Hello, I'm trying to connect my ESP32-S3-DevkitC-1-N16R8 to MATLAB, but I keep running into this error message when I press program on the hardware setup package for arduino:
  • INFO: esptool.py v3.0-dev
    Serial port COM11
    Connecting....
    WARNING: This chip doesn't appear to be a ESP32 (date codes 0x03700000:0x00000000). Probably it is unsupported by this version of esptool.
    Chip is ESP32-D0WDQ6 (revision 0)
    Features: WiFi, BT, Dual Core, Coding Scheme None
    WARNING: Detected crystal freq 0.00MHz is quite different to normalized freq 26MHz. Unsupported crystal in use?
    Crystal is 26MHz
    MAC: 00:00:00:00:00:00
    Uploading stub...
    Running stub...

    A fatal error occurred: Invalid head of packet (0x47)
What should I do to resolve this issue?

Probably your chip is unsupported by that version of esptool (from 2020). You can download a more recent version at https://github.com/espressif/esptool/releases.
If Matlab doesn't include some way to choose which variant you have, then it is unlikely it will work with your esp32-s3.
