First of all, thanks for the great platform! I’m new to PlatformIO but already got an example up and running — it’s been a great experience with the framework and the VS Code integration!
In my example, I’m using the Arduino Nano ESP32 but I’d like to also migrate another project from Arduino IDE over to PlatformIO: that one is using an Arduino Nano Matter board. My understanding looking at
Seems like at least the platform modification part (to platform-siliconlabsefm32) was started a year ago, but the builder script was never started or finished. I’ll step in there and finish it up.
Do you have a Sparkfun ThingPlus Matter? I have it to the point where I can at least build for that single board in a single configuration (Matter stack activated) and have the uploaders (JLink, Simplicity Commander, OpenOCD) in place.
If you have the hardware, please download + build + try to upload to the board. Check if the LED blinks and if the “Monitor” tasks outputs the expected serial text.
I’ve updated support for the actual Arduino Nano Matter. The project above now has a arduino_nano_matter environment. You can use the project environment switcher to select it. Does it upload and work?
@maxgerhardt, first of all, thank you so much for your help, I appreciate it so much!
I cloned your repo, selected the environment (VS Code shows env:arduino-nano-matter (pio-sparkfun-thingplusmatter-test) in the lower blue bar), did a clean build via PlatformIO: Clean, and then a PlatformIO: Upload. Here’s the output:
* Executing task: platformio run --target upload --environment arduino_nano_matter

The halted due to debug-request made me think I had a breakpoint set somewhere but I think I don’t (warning: I’m not a VS Code expert): I did a cmd-shift-P and selected Disable All Breakpoints, assuming this applies to PlatformIO and retried, with the same result.
The output looks good, the “halted due to debug-request” from OpenOCD is perfectly normal during the flashing procedure.
But the firmware is indeed not looking like it’s working, clearing lockup after double fault means it just immediately crashed. I’ll have a closer look with a binary analysis of the produced firmware and the reference firmware.
folders and re-upload the project to the Arduino Nano Matter? There now should also no more flood of warnings during the last step of the build (“x is not implemented and will always fail”).
Looks like now. When I click in the PlatformIO sidebar the Debug → Start Debugging action and afterwards Debug → Toggle Debug Console, I see:

and the same output as above in the Debug Console.
Interesting, on my Arduino Nano Matter, it uploads and ruins normally, continuously. But when debugging encounters the same MSC erase error. I’ll have to further look into this.
Adding Serial.println("Setup..."); to the above program’s setup() still works. However, adding Serial.begin(9600); Serial.println("Setup..."); instead again results in no blinking.
I also tried:
Serial.begin(9600); while (!Serial) {};
Serial.begin(9600); delay(5000);
but neither caused the LED to blink.
(I don’t think this matters but I also tried 3 different Apple USB-C cables and all 3 ports of my MacBook M1 — without success.)
The on-board SAMD11 chip which has a CMSIS-DAP debugger firmware flashed onto it should 100% suffice, no external J-Link needed. But for me, debugging also doesn’t work in the Arduino 2.0. Need to check that further.
works well, up to where the Arduino loop() exits back to main() and calls handle_serial_events().
There, it goes into lockup:
