Hello,
I’m currently facing an issue while trying to upload code to my BluePill board using PlatformIO. I have installed a bootloader on the board to enable USB programming, but I am encountering errors when attempting to upload firmware via the serial connection.
Setup Details:
- Board: BluePill (STM32F103C8)
- Bootloader: Installed (specify if it’s the Arduino bootloader or another one)
- IDE: PlatformIO
- Operating System: [e.g., Windows 10 / Linux / macOS]
PlatformIO Configuration:
Here’s what my platformio.ini file looks like:
ini
[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
upload_protocol = serial
upload_port = COM3 ; [or the appropriate port for your OS]
Error Message:
When I try to upload code, I receive the following error:
text
Error probing interface "serial_w32"
Cannot handle device "COM3"
Failed to open port: COM3
*** [upload] Error 1
Troubleshooting Attempts:
- I have verified that COM3 is the correct port and that it appears in Device Manager.
- I have checked that my USB-to-Serial drivers are installed correctly.
- I’ve tried different USB cables and ports and closed any applications that might be using COM3.
- I reset the BluePill board before the upload.
Questions:
- Is there a specific configuration I missed for USB bootloading on the BluePill?
- Could there be any conflicting issues I am not aware of?
- Is there a way to ensure that PlatformIO recognizes the USB programming setup correctly?
Any guidance or suggestions would be greatly appreciated.
Thank you!
