You matched the platformio.ini perfectly with the Arduino IDE settings, so there shouldn’t be a fault in there. A remaning thing would be the Arduino-ESP32 core version (as seen in Tools → Boards → Board Manager → esp32). If you use 2.0.4 core in the Arduino IDE, use
platform = https://github.com/platformio/platform-espressif32.git
in the platformio.ini to also use that in PlatformIO.
It says the flash is only 2MByte instead of 4Mbyte? Please use
board_build.partitions = bare_minimum_2MB.csv
in the platformio.ini instead.
The same result.

Creating esp32c3 image…
Merged 2 ELF sections
Successfully created esp32c3 image.
It really shouldn’t have 4MB as a flash size anymore if platform-espressif32/main.py at develop · platformio/platform-espressif32 · GitHub respects the platformio.ini.
Can you please do the following: In your project, create a folder called boards. In it, create the file esp-c3-32s-kit-2m.json with the content
{
"build": {
"arduino":{
"ldscript": "esp32c3_out.ld",
"partitions": "bare_minimum_2MB.csv"
},
"core": "esp32",
"f_cpu": "160000000L",
"f_flash": "80000000L",
"flash_mode": "dio",
"extra_flags": "-DARDUINO_ESP32C3_DEV",
"mcu": "esp32c3",
"variant": "esp32c3"
},
"connectivity": [
"wifi"
],
"debug": {
"openocd_target": "esp32c3.cfg"
},
"frameworks": [
"arduino",
"espidf"
],
"name": "ESP-C3-32S-KIT-2M",
"upload": {
"flash_size": "2MB",
"maximum_ram_size": 327680,
"maximum_size": 2097152,
"require_upload_port": true,

},

"vendor": "Espressif"
}
then, use just the platformio.ini:
[env:esp-c3-32s-kit-2m]
platform = https://github.com/platformio/platform-espressif32.git
board = esp-c3-32s-kit-2m
framework = arduino
upload_port = COM5
don’t forget to select this new environment in the project environment switcher after the platformio.ini was saved.
Then somehow it didn’t accept the platformio.ini modifications for the flash_size. Good that it’s working now. I’ll see if I can reproduce this an file an issue at Issues · platformio/platform-espressif32 · GitHub, this should be solved.
