CAUSE
The Arm Compiler does not guarantee to preserve the state of the exclusive monitor. This is why the __ldrex, __ldrexd, __strex and __strexd intrinsics are deprecated.
RESOLUTION
Either ignore the warnings or update the Arm CMSIS Pack to a version later than 4.3.0 to get these warning messages suppressed.
