I am unable to upload code to my STM32 blue pill. I am using a Mac and it was running very well, all of a sudden, after doing something in terminal, I am unable to use it since then. I tried uploading code from my Mac to an UNO and its also not working.
When I try uploading code to my STM32 blue pill this is the error that I am getting-
Arduino: 1.8.9 (Mac OS X), Board: "Generic STM32F103C series, STM32F103C8 (20k RAM. 64k Flash), Serial, 72Mhz (Normal), Smallest (default)"

the selected serial port does not exist or your board is not connected
This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.
Please help me with this. How do I successfully upload code to my STM32 blue pill?
