Hello Boris,

Appreciate your reply!

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino

board_build.flash_size = 32MB
board_build.f_flash = 80000000L
board_build.flash_freq = 80m

board_build.flash_mode = opi
board_build.arduino.memory_type = opi_opi
board_build.partitions = partitions.csv

board_upload.maximum_ram_size = 8388608

build_flags = 
    -DBOARD_HAS_PSRAM 
    -DARDUINO_USB_CDC_ON_BOOT=1
    -mfix-esp32-psram-cache-issue

upload_speed = 460800
monitor_speed = 9600

upload_port = /dev/cu.usbmodem14601
monitor_port = /dev/cu.usbmodem14601

partitions.csv

# Name,   Type, SubType, Offset,   Size,     Flags
nvs,      data, nvs,     0x9000,   0x6000,
otadata,  data, ota,     0xf000,   0x2000,
app0,     app,  ota_0,   0x20000,  0xE00000,
app1,     app,  ota_1,   0xE20000, 0xE00000,
spiffs,   data, spiffs,  0x1C20000,0x200000,
coredump, data, coredump,0x1E20000,0x10000,

And the main.cpp

#include <Arduino.h>

void setup() {
  Serial.begin(9600);
  delay(1000);
  Serial.println("ESP32-S3 Startup");
}

void loop() {
  Serial.println("Loop running");
  delay(1000);
}

The build is successful and with above configuration the esp32 memory and flash size is detected properly:

Advanced Memory Usage is available via "PlatformIO Home > Project Inspect"
RAM:   [          ]   0.2% (used 19176 bytes from 8388608 bytes)
Flash: [          ]   1.8% (used 267085 bytes from 14680064 bytes)

Yet, upon successful upload, the device enters into the infinite loop of crash:
