The debugger in Arm Development Studio 2021.2 doesn't work with
"ec = debugger.getExecutionContext(0)" because it's subsequently unable
to access memory. Fix it by switching to
"ec = debugger.getCurrentExecutionContext()".

The documentation for waitForStop() says:

"It is not needed after a call to stop() because stop() is blocking."

So, remove the call to waitForStop.

Since the documentation was a bit difficult to find, I'll make a note here.

For Development Studio 2021.2 it was in 
/opt/arm/developmentstudio-2021.2/sw/ide/plugins/com.arm.debug.interpreter.jython.api_2021.2.0.20211118_074138/doc/arm_ds.html
