The thread stack size was restricted due to some boards have really limited RAM sizes,
and out of heap memory on multiple threads tests.
The side effect was on the debug profile build, the tests will get stack overflow.
We need the build the test with debug profile in order to do the code coverage analysis.
So increased the thread stack size on FastModel targets.
FastModels targets are simulator running on the x86 hosts.
As the nature of non-RealTime x86 OS and FastModels, timing accuracy is not guaranteed
So skipping the time drifting tests on FastModel targets
Since target specific ticker drivers are not ready also features which uses ticker in upper layers may not work correctly and tests for these features.
We need to disable also failing higher level ticker related tests (by adding check if DEVICE_USTICKER symbol is available and raise #error [NOT_SUPPORTED] if not).
Update the SysTimer test to match the updated API. Changes are:
- increment_tick() renamed to _increment_tick() and explicitly
synchronized
-update_tick() replaced with resume() and a call to suspend() was added
before this
In pararell threads of "thread" test is a simple thread, but it seems that there is a difference in the stack used between Cortex-A and Cortex-M.
As a result of check, in Cortex-A, program aborts because of the lack of stack when PARALLEL_THREAD_STACK_SIZE is 384, workes properly when PARALLEL_THREAD_STACK_SIZE is 512 at least.
"malloc" test is used a simple thread that executes only malloc and free, but it seems that there is a difference in the stack used between Cortex-A and Cortex-M.
As a result of check, in Cortex-A, program aborts because of the lack of stack when THREAD_STACK_SIZE is 256, workes properly when THREAD_STACK_SIZE is 512 at least. Since it seems that the definition processing of "DEFAULT_STACK_SIZE" was gone from Mbed OS by updating CMSIS5/RTX5, I setted 512 directly for Cortex-A.
LowPoterTimer test gives sometimes failed result while testing measured time accumulation. The check which verifies if total number of elapsed milliseconds is valid fails. Test assumes that delta value equal to 1 ms is sufficient for all test cases, which is not true since in case where time measurement is performed few times in sequence the measurement error also accumulates and 1 ms might be not enough. To solve this problem delta value for milliseconds tests must be updated.
