Although my code builds and runs, when using GCC I am seeing errors in the editor window (red underlines). With ARMC6, there are no red underlines (but I can rarely get debug to work, so I prefer GCC) With GCC 9-2020-q2, the error appears I should stress the code builds with no warnings or errors…

Did you get a solution to this as I’m seeing exactly the same issue using GCC and MBed studio 1.4.4.

Maybe you need to see this topic. There are problems in a specific version of Mbed Studio.
