Which board to select for ESP32-S3-WROOM in PlatformIO?

I have an ESP32-S3-WROOM-1U and would like to use PlatformIO with vscode to program it, what board do I need to set in the platformio.ini file? I've tried:

[env:esp32s3box]
platform = espressif32
board = esp32s3box
framework = arduino
monitor_speed = 115200

but am getting the following output on the serial monitor:

ELF file SHA256: ad858c055791c095

E (153) esp_core_dump_flash: Core dump flash config is corrupted! CRC=0x7bd5c66f instead of 0x0

So I tried:

[env:esp32s3]
platform = espressif32
board = esp32s3
framework = arduino
monitor_speed = 115200

But am getting: ``Resolving esp32s3 dependencies... UnknownBoard: Unknown board ID 'esp32s3'

What `board` do I need to select to make this work?
Solution

  • Never had that exact message in PlatformIO but it sounds that your board has 8mb or flash and the esp32s3box has 16mb so PlatformIO can't write the binary correctly.

    The board type you specify in platformio.ini is just a pointer to a .h file in the platformio configuration that contains mapping of the pins and some preset bits of info like the cpu speed, flash size etc

    Most of the time if your board is pretty generic (no fancy stuff like built in screen, battery charger, camera etc) you can simply use some other generic board type, something like

    This one is 8mb flash

    [env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
monitor_speed = 115200

; try enabling or disabling this line
board_build.mcu = esp32s3

    I use this one a lot but I think it's for 4mb flash

    [env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200
