Arduino for STM32

You can try and

In my case the app was always compiled for upload with STLink (vector at 0x08000000), the same BIN worked when uploaded with Cube programmer, and it failed when uploaded with STLink. In the later case the FLASH was corrupted (empty), and the utility sw had a freeze.

Well, some of those registers (e.g. GPIO) are also defined in the libmaple core, and he still redefines them...

Anyway, I think we have to ask again the OP which core he actually used.

It will not compile for libmaple, because it uses digitalToggle() function, which does not exist in libmaple core...
I am sure PIO uses the official ST core

I don't think that it is for libmaple.
Under "Instalation" is stated:

The library was developed using Platformio and STM32duino

.

I also observed strange STLink upload behavior during the CDC bootloader development. At a certain point I could not upload the BIN file with STlink but I could upload it using Eclipse and starting the debug session, or with STMCUbe programmer. And the fail uploads varied somehow dependent on the co...

error resetting after download: usb_reset: could not reset device, win error: Ein nicht vorhandenes Gerät wurde angegeben. state(8) = dfuMANIFEST-WAIT-RESET, status(0) = No error condition is present This is does not really mean an error, do not pay attention to this, the upload should be successful.

Can you post the complete Arduino generated message?

It looks to me like a positive feedback regulation instead of a negative one, or it is too slow. Maybe inverting the steering direction?
