After a new target is attached to the MBED Studio it is recognized and both “PLAY” for execution
and “DEBUG” button for debugging are displayed. Now, if the application is started by “PLAY” and not by
“DEBUG”, the “DEBUG” button will be disabled and the IDE stucks in this mode even if it is restarted or target is reset, reconnected,…
If another, new target of different type is connected, the debugging button is shown again and the application can be debugged until the PLAY is pressed again.
Problem reproduced with FRDM-KL25Z, STM32L476G-DISCO, STM32F429I-DISC1 (all I have).
Application : blinky
MacOSX: 10.15.5 (recent).
