ATOMS3 code load failure

  • Trying to load arduino code for the first time from IDE. Updated all my library files. Fails with the following:
    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

    Running stub...

    A fatal error occurred: Invalid head of packet (0x47)
    A fatal error occurred: Invalid head of packet (0x47)

    An error occurred while uploading the sketch

    I did hold down the reset button until the light turned green.

  • @dheco Well, I have one on I cannot yet try the Arduino IDE, but the chip is actually
    ESP32-S3FN8, not ESP32-D0WDQ6 as the esptool reported.
    So, hopefully someone in this community will tell us which Board to select.
    (AtomS3 is not yet listed in the Board Selection menu)

  • Did you update ESPtool?

  • @ajb2k3 Yes, I am running the latest 1.0.4.

  • There was a reply from M5Stack about this on Twitter.
    Apparently support is delayed because the programmer behind it is off sick at the moment.

  • Looks like I need to use M5unified also?

  • It's not that simple because the ESP32 S3 is not the same as the current chips used in M5Stack products.

  • Went thru and tried to convert to M5unified, now IMU and SD code does not compile..
    error: 'SD' was not declared in this scope
    error: 'class m5::M5Unified' has no member named 'IMU'

  • Looks like updates dropping regularly, the M5 board file latest update 2.0.6 may add some support but broke other code so I am sitting at 2.0.5 right now. Could not get unified to work because of errors with IMU and GFX issues so I stopped trying that for now. Will test again next week.
