upload via platformio

[tcurdt]

This is what I tried:

$ st-info --probe
Found 1 stlink programmers
  version:    V2J17S4
  serial:     54FF67064882565217411887

...
2023-02-25T17:29:37 INFO common.c: Flash written and verified! jolly good!

Now when I connect to the usb serial I the following message in a loop:

Congratulations, you have installed the STM32duino bootloader
See https://github.com/rogerclarkmelbourne/STM32duino-bootloader

For more information about Arduino on STM32
See https://www.stm32duino.com

That looks like the bootloader and the welcome sketch works correctly.

I now change the platformio.ini to

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
upload_protocol = dfu

but when running pio run -t upload I am getting an error (which seems to be related to an outdated dfu-util)

Updating it brew install dfu-util and changing the reference in ~/.platformio/packages/tool-stm32duino/maple_upload, the upload succeeds:

...
Download done.
DFU state(8) = dfuMANIFEST-WAIT-RESET, status(0) = No error condition is present
Resetting USB to switch back to runtime mode

but after that upload the bootloader seems to be gone again. No usb serial shows up anymore.

I then also tried

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
upload_protocol = dfu
board_upload.offset_address = 0x2000

Since the bootloader was working, this is rather a platformio issue, right?

But is dfu the right upload method to use with the bootloader?

It just has to be written at the correct address? Which is 0x8002000?

While digging through some github issues I also found these settings:

board_build.core = maple
build_flags = -DSERIAL_USB -DGENERIC_BOOTLOADER

Just not sure whether they make sense or not.

I would be very thankful for some input.

This bootloader was written by LeafLabs to work with the Arduino IDE.

Try posting to www.stm32duino.com to see if someone can help you make it work with another IDE

I will - but could you just confirm how it should work in general?

What's the mechanism to upload and the address is for the sketch is 0x8002000?

I have it working and this is my platformio.ini configuration file

[env:genericSTM32F103C8] ; Usando bootloader generic_boot20_pc13.bin
platform = ststm32
board = bluepill_f103c8
board_build.mcu = stm32f103c8t6
framework = arduino
upload_protocol = dfu
upload_command = dfu-util -a 2 -D $SOURCE

Then when i do an Upload the firmware:
