Hello,
I just found out about PlatformIO as a nice alternative to using the Arduino IDE and am trying out the VSCode extension at the moment. I want to upload a program using a USB-to-serial converter to a Black Pill (similar to Blue Pill STM32F103C8). This is my platformio.ini:
[env:genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = arduinoupload_protocol = serial
; upload_port = /dev/ttyUSB0
upload_speed = 115200
When I try to upload, I get the following log though:
Building .pioenvs/genericSTM32F103C8/firmware.bin
DATA: [= ] 12.3% (used 2520 bytes from 20480 bytes)
PROGRAM: [== ] 22.0% (used 14424 bytes from 65536 bytes)
Configuring upload protocol…
AVAILABLE: blackmagic, dfu, jlink, serial, stlink
CURRENT: upload_protocol = serial
Looking for upload port…
Auto-detected: /dev/ttyUSB0
Uploading .pioenvs/genericSTM32F103C8/firmware.bin
stm32flash Arduino_STM32_0.9Using Parser : Raw BINARY
Cannot handle device “/dev//dev/ttyUSB0”
Failed to open port: /dev//dev/ttyUSB0
*** [upload] Error 1
The same happens when I uncomment the upload_port
line. When I take away the “/dev/” from upload_port
, I get another error, which tells me to specify the upload port correctly.
Now it seems that the error comes from the “/dev/” prefix in front of the device name. Is there a simple way to fix this? It seems that PlatformIO and the arduino_stm32
interface handle the device port differently.
