Wrong baud rate, when trying to upload a sketch

[GiorgosXou]

Describe the bug Trying to upload any sketch, happens to use the wrong baud rate and fails to do so.

• vim-arduino runs with -b19200:

  "/home/xou/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/bin/avrdude" "-C/home/xou/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/etc/avrdude.conf" -v -V -patmega328p -carduino -P/dev/ttyUSB0 -b19200 "-Uflash:w:/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/build/test0.ino.hex:i"

• While the arduino IDE runs with -b115200:

  /home/xou/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/bin/avrdude -C/home/xou/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/etc/avrdude.conf -v -patmega328p -carduino -P/dev/ttyUSB0 -b115200 -D -Uflash:w:/tmp/arduino_build_782589/test0.ino.hex:i

System information

• OS: Arch Linux
• Vim: Neovim v0.8.1
• Arduino: 1.8.19
• CLI version: 0.29.0-arch
• ArduinoInfo:

  Board         : arduino:avr:uno
  Programmer    : arduinoasispatmega32u4
  Port          : /dev/ttyUSB0
  Baud rate     : 115200

  Verify command: arduino-cli compile -b arduino:avr:uno -p /dev/ttyUSB0 -P arduinoasispatmega32u4 --build-path "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/build" -v "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/test0.ino"

  (Brand new installation of Arduino and vim-arduino)

---

To Reproduce Steps to reproduce the behavior:

1. Open a sketch like Blink.ino
2. Upload it with Arduino IDE
3. Upload it with vim-arduino

---

Expected behavior It should had used the correct baud rate and get uploaded (?)

---

Working command Running the command just with the correct baud rate just works and gets uploaded.

Additional context Here's the output of vim-arduino when uploading:

Error during Upload: Failed programming: uploading error: exit status 1

Have you tried setting let g:arduino_serial_baud = 115200?

[GiorgosXou]

(Sorry for the late response) Yes, it doesn't work, it only changes the serial baud-rate that it is supposed to listen to, and not the one for uploading a sketch

[stevearc]

Ah, sorry I misread that. According to the debug information, the "verify" command it's running is

arduino-cli compile -b arduino:avr:uno -p /dev/ttyUSB0 -P arduinoasispatmega32u4 --build-path "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/build" -v "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/test0.ino"

That means that the upload command is going to just add a -u to it

arduino-cli compile -b arduino:avr:uno -p /dev/ttyUSB0 -P arduinoasispatmega32u4 --build-path "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/build" -u -v "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/test0.ino"

If you run that manually from the command line, do you see the same error? If so, is there any invocation of arduino-cli that you can get to work? I don't see any arguments to specify the upload baud rate.

[GiorgosXou]

Not specifing a programmer also works:

arduino-cli compile -b arduino:avr:uno -p /dev/ttyUSB0 --build-path "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/build" -u -v "/home/xou/Desktop/xou/programming/hardware/arduino/uno/test0/test0.ino"

Used platform Version Path

Those work too:

arduino-cli compile --fqbn arduino:avr:uno
arduino-cli upload --fqbn arduino:avr:uno -p /dev/ttyUSB0 --verbose

[stevearc]

Well, if it's the programmer that's causing the issue, can you let g:arduino_programmer = '' and try again? That should remove the programmer from the compile/upload command.

I'm away from my computer that has arduino things installed atm, but if I remember correctly I think it's awkward/not possible to clear the programmer using :ArduinoChooseProgrammer, which is why you have to set the variable directly. If this works I'll tweak the command to make it easier to clear the programmer.

[GiorgosXou]

Ah... there's a -None- option in :ArduinoChooseProgrammer that I've managed to somehow miss, I'm sorry, it uploads just fine if I do select the -None- option

I was used to the Arduino IDE where the option Arduino as ISP worked as the default programmer when the uno was connected by the usb
