Board

ESP32-S3-WROOM-1U-N4R8

Device Description

For reference, below is my board.json configuration, and I believe the flash configuration here should be correct:

{
  "build": {
    "arduino":{
      "ldscript": "esp32s3_out.ld",
      "memory_type": "qio_opi"
    },
    "core": "esp32",
    "extra_flags": [
      "-DBOARD_HAS_PSRAM",
      "-DARDUINO_ESP32S3_DEV",
      "-DARDUINO_USB_MODE=0",
      "-DARDUINO_RUNNING_CORE=1",
      "-DARDUINO_EVENT_RUNNING_CORE=1"
    ],
    "f_cpu": "240000000L",
    "f_flash": "80000000L",
    "flash_mode": "qio",
    "hwids": [
      [
        "0x303A",
        "0x1001"
      ]
    ],
    "mcu": "esp32s3",
    "variant": "esp32s3"
  },
}

I don't know where this problem comes from? Maybe it's the USB? Or I made some stupid mistakes in the code that I didn't notice.

Description

I am developing a HID project based on the ESP32S3 using platformIO. Everything is going smoothly. However, today when I tried to use Preferences.h to persist some data, I found that I couldn’t do it.

I found a similar issue at #8429, and later I confirmed that the flash of the ESP32-S3-WROOM-1U-N4R8 I am using is operating in qio mode, so the solution in this issue does not work to me.

Sketch

AT8236HID::AT8236HID(uint8_t in1_pin, uint8_t in2_pin, float speed)
    : _in1_pin(in1_pin), _in2_pin(in2_pin), _speed(constrain(speed, 0.0f, 1.0f))
{
    pump_prefs.begin(pref_namespace, true);

    if (!pump_prefs.isKey(pref_device_id))
    {
        pump_prefs.end();
        pump_prefs.begin(pref_namespace, false);
        pump_prefs.putUInt(pref_device_id, 2);
        pump_prefs.end();
        pump_prefs.begin(pref_namespace, true);
    }

    _device_id = pump_prefs.getUInt(pref_device_id);
    pump_prefs.end();
}

auto AT8236HID::_onSetFeature(uint8_t report_id, const uint8_t *buffer, uint16_t len) -> void
{
    feature_t feature{};
    memcpy(&feature, buffer, sizeof(feature));

    if (feature.device_id != _device_id)
        return;

    _device_id = feature.new_device_id;

    pump_prefs.begin(pref_namespace, false);
    pump_prefs.putUInt(pref_device_id, _device_id);
    pump_prefs.end();
}


I initialize them here:

    const char *pref_namespace{"app-name"};
    const char *pref_device_id{"device_id"};
    Preferences pump_prefs{};

Debug Message

In USBHID mode, I don't know how to obtain the debug output.
