Hello i can’t fix the parameters of a lolin S3 mini pro ! i use [env:lolin_s3_mini] platform = espressif32 board = lolin_s3 framework = arduino build_flags = -D ARDUINO_USB_MODE=1 -D ARDUINO_USB_CDC_ON_BOOT=1 but i still have errors on download ! what i have missed ?? thanks

If I get the technical specs correctly it is using an ESP32-S3FH4R2 which have 4 MB Flash and 2 MB PSRAM. So this configuration should work. Of course you would also need the additional settings for USB-CDC: build_flags = -D ARDUINO_USB_MODE=1 -D ARDUINO_USB_CDC_ON_BOOT=1
