Arm Mbed OS support forum

Can't see and can't change to existing program

I have a workspace with 3 mbed programs in it. Yesterday I edited one of them and then at the end of the day exited from Mbed Studio and shut the computer down.
Today when I launched Mbed Studio an other program is selected as active program and I can’t change it. WHY???!!

Hello,

Your Mbed OS has folder icon what is wrong, it must be a gear. So it seems the Mbed OS library cannot be initialized. In the basic, the Mbed Studio thinks the MbedOS is not in the project.

Just try to delete the MbedOS folder and right click on project folder and Add library from - https://github.com/ARMmbed/mbed-os
