ESP32-S2 (Lilygo T8) support?

alexander.beck.konst · February 19, 2022, 7:04am

Hi,
I plan to use the newer esp32-s2 in future (LILYGO® T8 V1.7.1 ESP32 Modul 8MB PSRAM TF KARTE 3D Antenne WiFi Drahtlose Bluetooth Entwicklung Board für Arduino Micropython|antenna wifi|cards 3dcard card - AliExpress - Lilygo T8 V1.7.1) for some of my projects, but currently I am stuck in the first steps. The S2 isn’t really well supported by platformio so far. I thought after 2 y on the market the chip would work out of the box, but well…

So I tried to use some of the configuration variants based on attempts of others, but without luck

[env:Lily-esp32-t8]
framework = arduino
platform = espressif32
platform_packages =
  toolchain-xtensa32s2
  framework-arduinoespressif32@https://github.com/espressif/arduino-esp32.git#master
  platformio/tool-esptoolpy@~1.30100

board = esp32doit-devkit-v1
board_build.mcu = esp32s2
;board_build.partitions = huge_app.csv
build_unflags =
  -DARDUINO_ESP32_DEV
  -DARDUINO_VARIANT="esp32"
build_flags =
  -DARDUINO_MAGTAG29_ESP32S2
;  -DARDUINO_SERIAL_PORT=1
;  -DARDUINO_VARIANT="adafruit_magtag29_esp32s2"
  -DARDUINO_VARIANT="esp32s2"  
  -DBOARD_HAS_PSRAM

monitor_speed = 115200
upload_port = COM11

Even when using a blank main.cpp like:
#include <Arduino.h>

void setup() {
}

void loop() {  
}

I get the following error log:

any ideas how to fix that?

Correct, issue Support for the latest Arduino v2.0 · Issue #619 · platformio/platform-espressif32 · GitHub is holding you back.

alexander.beck.konst:

platform = espressif32
platform_packages =
  toolchain-xtensa32s2
  framework-arduinoespressif32@https://github.com/espressif/arduino-esp32.git#master
  platformio/tool-esptoolpy@~1.30100

Mhm no, better use the tasmato platform, it has cleaner ESP32 2.0.2 support.

[env:esp32-s2-saola-1]
platform = https://github.com/tasmota/platform-espressif32/releases/download/v2.0.2idf/platform-espressif32-2.0.2.zip
framework = arduino
board = esp32-s2-saola-1
monitor_speed = 115200
upload_port = COM11

should be all you need. (from Esp32-s2-saola-1 --> Error: This board doesn't support arduino framework! - #9 by fabiobertolini)
