Unable to upload Seeed Studio XIAO code

PlatformIO IDE
1

I am trying to switch to Visual Code Studio from Arduino because I want to use freeRTOS on my Seeed ESP32C3 Studio.
I carefully followed all the instructions I could find, did all the prerequisites and the simply program I wrote that does nothing but print “hello world” compiles, but platformIO refuses to upload it.
I tried through VCS and directly with this line.

./.platformio/penv/bin/platformio run -d ./Documents/PlatformIO/Projects/RTOSagain -t upload

But it keeps telling me “No device found on cu.usbmodem2101” despite the fact that the OS sees, as does my Arduino IDE, that does upload code.

My configuration file looks like this…

[env:seeed_xiao]
platform = atmelsam
board = seeed_xiao
framework = arduino
monitor_speed = 9600
upload_protocol = sam-ba

Any help much appreciated

This might help someone point me in the right direction.

Nope. You’ve selected the Seeeduino XIAO with an Atmel SAMD21 chip. You have a totally different XIAO. The one with the ESP32C3. You need this one

https://docs.platformio.org/en/latest/boards/espressif32/seeed_xiao_esp32c3.html

with a platformio.ini of just

[env:seeed_xiao_esp32c3]
platform = espressif32
board = seeed_xiao_esp32c3
framework = arduino
monitor_speed = 9600

Thanks Max,

I changed it, but I fear the only progress I made is I now get an error 2.

No, wait… It is an ESP32S3 not a C3; I changed it and it is now works!!! Thanks for your help!!
