Evaluation boards (Discovery or Nucelo) with virtual com port for debugging
Greetings,I'm new to STM32 MCUs and bought an evaluation board (STM32F072B-DISCO).I get along surprisingly well, but there is one thing that bothers me:This combination of MCU (Cortex M0) and ST-Link/V2 seems to lack a virtual COM port for debugging....
Resolved! STM32U575 programming flash from ST-Link/V2
Hello,I have not been able to program the MCU from ST-Link/V2 (Serial 2-wire) - I suppose this is possible??Bonus info: Debugging with J-link and same (serial 2-wire) works fine.Thanks in advance - Michael
