for the ESP32 DevKitC v4, the pio board configuration should be like this:

[env:esp32dev] platform = espressif32 board = esp32dev framework = arduino board_upload.flash_size = 4MB build_flags = -DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
board_upload.flash_size = 4MB
build_flags =
   -DBOARD_HAS_PSRAM
