Cortex-A in general will require more stack space than Cortex-M.
Therefore it is necessary to divide the definition by "#ifdef" as same as other test. By using its value CI test sequece is carried out.
For example:
TESTS\mbedmicro-rtos-mbed\basic\main.cpp

In Cortex-A, DEFAULT_STACK_SIZE is 2048 byte. Maybe in Cortex-M, it is 256Byte.

I just wondered if that macro should not be DEFAULT_STACK_SIZE for any cortex. Russ, what do you think?

#else
#define THREAD_STACK_SIZE 256
#endif

DigitalOut led1(LED1);
volatile bool should_exit = false;
