Hi @Atoussa_Tehrani,
Running a program on LPC1768 should work correctly in Mbed Studio. It does not work only in Keil Studio Cloud (we are working on a new firmware for LPC1768 to enable it).
We will do more checks. In the meantime can you please check also an mbed-os-example-blinky? I wonder if the problem is connected with baremetal.
Thanks,
Arek - Studio team
