一、选用esp32-s3-devkitc-1开发板
二、修改platformio.ini
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
monitor_speed = 115200
; 指定为16MB的FLASH分区表
board_build.arduino.partitions = default_16MB.csv
; 指定FLASH和PSRAM的运行模式
board_build.arduino.memory_type = qio_opi
; 预定义宏，启用PSRAM
build_flags = -DBOARD_HAS_PSRAM
; 指定FLASH容量为16MB
board_upload.flash_size = 16MB
