This board was part of the 2.9.0 release of Arduino Core for STM32. I had thought it would automatically be part of the 18.0.0 STM32 platform release for PlatformIO, but apparently there is a manual process? Happy to create a PR if that is what is needed. Thanks!

The "Buy" link for the Cygnet doesn't even work on https://blues.com/feather-mcu/. Where's the board's documentation, schematic, etc.? Do you have the board on hand? How does uploading work? It says

Do Swan and Cygnet require a CORTEX SWD Programmer?
No, but we recommend getting one! Swan and Cygnet can be programmed over USB for both Arduino and CircuitPython use,

So is it using the "STM32CubeProgrammer (DFU)" upload method in the Arduino IDE or how does this work?

FYI, I have the a work in progress board definition, which compiles sketches just fine, but it won't be uploading via USB (expects ST-Link by default). Also, PlatformIO doesn't yet have a package for the STM32CubeProgrammer, so if that's needed for the DFU upload, there is more base work to be done.

The "Buy" link for the Cygnet doesn't even work...

It's a brand new board, and we were hoping to have it functional in PlatformIO before selling it, because PIO provides one of the best development experiences.

Where's the board's documentation, schematic, etc.?

It is ready but not published while we await support. The main MCU is the STM32L433CCT6.

Do you have the board on hand?

Yes, and we are happy to test anything you come up with.

So is it using the "STM32CubeProgrammer (DFU)" upload method in the Arduino IDE... ?

Yes, that is correct.

PlatformIO doesn't yet have a package for the STM32CubeProgrammer, so if that's needed for the DFU upload, there is more base work to be done.

It would be AMAZING if you guys could get it in there. However, this has been true for the "Swan R5" for over a year now. While it would be very nice to have, it doesn't appear to be mandatory.

Is the USB-DFU upload protocol compatible with the dfu-util or does it need STM32CubeProg? What VID/PID does the board show up under when in DFU mode? How does it enter DFU mode? Via a 1200bps touch, or a DTR toggle?

Is the USB-DFU upload protocol compatible with the dfu-util or does it need STM32CubeProg?

I think it is compatible with dfu-util, but I don't know for sure. It should work similar to the way you've implemented the Swan R5.

What VID/PID does the board show up under when in DFU mode?

Bus 001 Device 027: ID 0483:df11 STMicroelectronics STM Device in DFU Mode

How does it enter DFU mode?

Manually, via BOOT and RESET buttons.

When you download + open https://github.com/maxgerhardt/pio-cygnet-test in VSCode and use the "Verbose Upload" project task, does it upload?

It does upload, yes:

I've made the board definition activate the USB serial by default, otherwise Serial is the UART serial.. probably most users will expect Serial to be using the USB serial, right?

Can you git pull the project again, upload it, and make sure the LED is blinking and the serial monitor shows the blinky output?
