No core dump partition found

Using ESP32-S3-DEVKIT-C1
Get “esp_core_dump_flash: No core dump partition found!:” message when running program. What am I missing to prevent this message? (coming up empty handed googling on this one)

Full output:

  while (!Serial)

    int available_PSRAM_size_after = ESP.getFreePsram();
    ESP_LOGI(TAG, "PSRAM Size available (bytes): %d", available_PSRAM_size_after); // Free memory space has decreased
    ESP_LOGE(TAG, "PSRAM not available.  HALTING");
    while (1)

And have you tried to add a cordump partition per Core Dump - ESP32 - — ESP-IDF Programming Guide latest documentation?

Thank you. It is interesting to me that the discussion on partitions from which I got my default_partitions.csv file had no mention of the core dump partition. I wonder if I really will ever use it.

How did you enable the core dump flash for an Arduino project? I had read that you had to enable this in the menuconfig of the ESP-IDF

Good morning in the morning!
I’m programming an ESP32-CAM and I think I don’t need the coredump feature. So I don’t want to reserve a place for coredump in the partition table.
How can I configure coredump in Arduino framework in order to disable it and not have the error 'No coredump partition found!"?

Maybe it’s hardcoded to look for one (–> ask in Issues · espressif/arduino-esp32 · GitHub). In any case, I think you can set the partition size for the coredump to only a few kilobyte, so they shouldn’t have an impact on anything.

Thank you very much Max!
I’ll ask there
