Platformio-core: STM32F0 upload failing

[zgoda]

Solution

Please add to platformio.ini

[env:myenv]
board = ...
upload_protocol = stlink

---

$ pio run --target upload

Port is /dev/stlinkv2_6 so let's follow advice in another approach:

$ pio run --target upload --upload-port /dev/stlinkv2_6 
.clang_complete  .gitignore       .pioenvs/        src/             
.gcc-flags.json  lib/             platformio.ini   .travis.yml

------------------------------------------------------------------------------------------------------------------------
MethodWrapper(["upload"], [".pioenvs/disco_f051r8/firmware.bin"])
scons: *** [upload] /dev/stlinkv2_6/firmware.bin: Not a directory

Port is accessible, of course:

$ ls -la /dev/stlinkv2_6 
lrwxrwxrwx 1 root root 15 maj 20 11:53 /dev/stlinkv2_6 -> bus/usb/003/003

Code builds without problems:

Could you copy manually without root permissions?

cp .pioenvs/disco_f051r8/firmware.elf /dev/stlinkv2_6

[zgoda]

$ LANG=C cp .pioenvs/disco_f051r8/firmware.elf /dev/stlinkv2_6
cp: error writing '/dev/stlinkv2_6': Invalid argument

[ivankravets]

Do you need any help?

[zgoda]

I'd like to know where is the problem - my board, my environment or PlatformIO components. I can replace board if it's not supported or I can try to fix my environment.

This is this exact kit

Texane stlink tool works fine:

Hi @zgoda
Looks like your kit only supports uploading over STlink.
Could you try upload_protocol = stlink option in your platformio.ini?

[zgoda]

Thank you @valeros, this works fine.

[ivankravets]

@zgoda Please give PlatformIO repository a star ⭐ https://github.com/platformio/platformio/stargazers

Thanks a lot!

[ivankravets]

@valeros please specify stlink upload protocol for the boards without ARM mbed bootloader.

[bfarayev]

Thanks @valeros Adding upload_protocol = stlink to platform.ini solved the issue for me. I was using STM32F411 board with stlink.

[ivankravets]

@bfarayev it should work automatically since 2.9.2 release. What is your PlatformIO CLI version? Could you share here your platformio.ini?

[bfarayev]

@ivankravets well, I'm using 2.10.3. My platform.ini file was like this:

[env:nucleo_f411re]
platform = ststm32
framework = mbed
board = nucleo_f411re

I was suspecting if it's because I created this project long before. However, I initialized a new one and again, platform.ini file looks similar:

[env:disco_f407vg]
platform = ststm32
framework = mbed
board = disco_f407vg

[ivankravets]

@bfarayev Thanks, I got you now. The stlink protocol is set by default only for the disco_* boards where the mbed disk is used for nucleo_*.

In this case, you need manually force the upload_protocol as you do it.

[TravisJoe]

This should probably be done on the Nucleo boards as well. Just ran into the same issue.

can you say that whats exactly in you ini file ?
I hace to save firmware.bin somewhere and flash it using st-flash in another terminal
