Hi everyone,
I have followed the tutor at STM32 Bootloader | Programming STM32 using usb cable | Flashing bootloader in STM32 | Arduino IDE - YouTube and successfully installed the SMT32 card as shown.
I have put the link to : http://dan.drown.org/stm32duino/package_STM32duino_index.json in the preferences.
BUT
It does not work. The card does not appear in the card list.
Regards,
