Started with a STM32F072 Nucleo with Keil MDK using ST-Link of Evaluation board.
Managed to do printf()/putchar() output to µVision Serial Debug (printf) Viewer via EventRecorder (DAP).
But: How to get input (do not see an option for EventRecorder)?
How to configure UART (which?) to get STDIO (STDOUT and STDIN) through ST-Link-USB.
How to communicate from/to Nucleo board application via STLink Virtual COM Port with terminal program on PC?
Checked SB61, SB62, SB63 of Nucleo board, all three are open, so PA2/PA3 should go as Tx/Rx to ST-Link (CN3 also open).
