W32-SC01 Plus fully working with PSRAM

ESPHome
1

In case anyone could do with a working config, this is the right way to get PSRAM to work (for e.g. displaying an image) in ESPHome for the W32-SC01:

esp32:
  board: esp32-s3-devkitc-1
  flash_size: 16MB
  framework:
    type: esp-idf
    sdkconfig_options:
      CONFIG_ESP32S3_DEFAULT_CPU_FREQ_240: "y"
      CONFIG_ESP32S3_DATA_CACHE_64KB: "y"
      CONFIG_ESPTOOLPY_FLASHMODE_QIO: y
      CONFIG_SPIRAM_FETCH_INSTRUCTIONS: y
      CONFIG_SPIRAM_RODATA: y
      CONFIG_ESP_TASK_WDT_TIMEOUT_S: "10"
      COMPILER_OPTIMIZATION_SIZE: y
      CONFIG_SPIRAM_USE_CAPS_ALLOC: y

psram:
  mode: quad
  speed: 80MHz

And this is my simple image display snippet (not complete, but you get the idea) that works with it (without PSRAM, you can’t download images)

      - logger.log: "Failed to download image"
