Adafruit ESP32-S2 Feather wrong specification

See original GitHub issue

Hi, regarding to the specs the FeatherS2 has 16MB Flash instead of 4MB and 8MB RAM. So I think (I’m relatively new and therefore not sure) "flash_size": "16MB", , "maximum_size": 16777216, , "extra_flags": "-DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue", should be correct

featheresp32-s2.json boardfile Not sure how the size of the SPI RAM can be saved in the board file. Would be nice if someone could take a look at it

board_build.extra_flags = -DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue
board_upload.flash_size = 16MB
board_upload.maximum_size = 16777216
board_build.partitions = default_16MB.csv
board_build.variant = um_feathers2

works fine. Also the ESP.getFreePsram() command shows 8351975. The only problem is, that the board doesnt connect to usb, also mentioned here No USB Serial port available #4728 but this isnt a pio bug. (Tested this with the arduino framework platform_packages = platformio/framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.0-alpha1 is this enough? or espidf required?)
