"sh: stm32flash: command not found" after fresh install of PIO

[steffentrumpf]

While trying to upload to a "Generic STM32F103C8" via serial I get the following error: "sh: stm32flash: command not found".

It has been working flawlessly before. After messing around with an F4 core, it doesn't work anymore. I tried removing VS code and PIO including, what I think, all background files. After a fresh install I get the same error.

When not having a device plugged in I get the following message:
"Error: Please specify upload_port for environment or use global --upload-port option.
For some development platforms it can be a USB flash drive (i.e. /media//)
*** [upload] Explicit exit, status 1"

I tried a complete reinstall of macOS and it is still not working.

Any Idea why stm32flash is not installed/working?

OS: macOS 10.14.6
PIO Core: 4.0.0
VS code: 1.36.1

Same here

And after install stm32flash via Homebrew, it still not work.

Having the same issue on Linux, using the STM32F103C8/B and bluepill_f103c8/_128k board variants. A quick which stm32flash from the VSCode terminal doesn't find executable either, although that may be unrelated. The file is present in /home/pfeerick/.platformio/packages/tool-stm32duino/stm32flash/stm32flash and will execute if run run manually.

Edit: After copying, /home/pfeerick/.platformio/packages/tool-stm32duino/stm32flash/stm32flash to /home/pfeerick/.platformio/penv (as that directory is in the path), stm32flash was found.

I then ran into #138 as mentioned above... resulting in needing to add /dev/to line 241 of platforms/ststm32/builder/main.py. I'm guessing an update to stm32flash is responsible for that issue.

Thanks a lot!
I did the things you mentioned and they worked.

BTW: On macOS 10.14 here.

Confirm having the same issue, and following these steps (including the addition to line 241) could solve it and be able to upload to the board normally. Thanks a lot!

I would add that on linux the error is:

Uploading .pio/build/bluepill_f103c8/firmware.bin
sh: 1: stm32flash: Permission denied
*** [upload] Error 127

somewhat misleading. But replacing UPLOADER to full path and removing the basename trimming of the UPLOAD_PORT works:

elif upload_protocol == "serial":
    env.Replace(
        UPLOADER="/home/atti/.platformio/packages/tool-stm32duino/stm32flash/stm32flash",
        UPLOADERFLAGS=[
            "-g", board.get("upload.offset_address", "0x08000000"),
            "-b", "115200", "-w"
        ],
        UPLOADCMD='$UPLOADER $UPLOADERFLAGS "$SOURCE" "$UPLOAD_PORT"'
    )
....

Thanks for reporting! Should be fixed in the upstream version:

[env:upstream_develop]
platform = https://github.com/platformio/platform-ststm32.git
board = ...
