In `ticker speed` test case execution time of ticker API functions is measured using Timer object. Test replaces original ticker handler for testing purposes, so test should not relay on higher level ticker based features(like Timer).
Use low level ticker API for time measuring.
DEVICE_EMAC is defined only for boards with default Ethernet emac.
It is not defined for example for Realtek RTL8195AM board that
does not have Ethernet. Removed the check for device emac from emac
greentea tests.
Made to prevent timeout if a single test case fails. The goal is that
each test case might wait only half of the remaining time reserved for
running TCP test cases.
In mbed-os-tests-mbed_hal-common_tickers/Microsecond ticker overflow test, some targets
would fail to catch specified ticker value near overflow in time and so fail. This commit
alleviates the issue by checking ticker value range rather than one exact ticker value near
overflow.
Serial buffer must be flushed before entering deep sleep mode. In the test this is done by the additional delay which is implemented on the busy loop which decrements given value down to 0 (`void wait_cycles(volatile unsigned int cycles)`). This solution is not appropriate since it is very target specific and the cycles value has been already increased few times. Additionally very big number of loop cycles which is suitable for fast targets may take much longer on slower boards and results in test timeout.
It has been verified that 20ms is sufficient delay for the green-tea transmission. In this test we cannot simply use `wait_ms(20)` since this potentially may put board to sleep and wake up using lp ticker. The test re-initialzies the lp ticker(disables ticker interrupt) and this operation may break the schedule and time tracing by the upper layer. But we can use us ticker which is not affected by this test. The solution is to add a delay routine based on busy loop and us ticker only. This way are able to wait exactly 20 ms.
The test sometimes fails on NRF51_DK (test case: "Test: LowPowerTimer - time measurement 1 ms.") in morph tests.
The test verifies if LowPowerTimer class correctly counts elapsed time. Sometimes we got measured ~1600 us for delay 1000 us (delta 550 us).
The delay is performed using `wait_us()` function which for delays greater than or equal to 1 ms (our case) calls `Thread::wait((uint32_t)ms);`. This causes rescheduling and potentially can put board into sleep (deep sleep mode is disabled by `wait_us()`). For our test purposes we don't need rescheduling/sleep since this actions takes extra time and have influence on the time measurement accuracy.
The solution is to implement function for delay which is based on busy loop and uses us ticker. It has been verified that this solves the problem. With this fix when measurement of 1 ms is repeated 1000 times we got usually measured time equal to ~1080 us, and sometimes ~1300us (checked that this is caused by systick interrupt handling). Since this is test for drivers layer and the results are acceptable I decided to not disabling systick in the test).
As we do not include rtx_lib header file anymore, these symbols are not available.
Use core util for if ISR is active. And for OS tick, pull in os_tick header file.
Mark mbed-os-tests-mbed_hal-common_tickers/time_cpu_cycles not in-lined.
Otherwise, time_cpu_cycles may be in-lined somewhere and takes different
CPU cycles on invocation.
Increase timeout for netsocket TCP and UDP tests. Old timeout
(240 seconds) was not enough for slower devices to complete the
tests.
Accept error codes NSAPI_ERROR_CONNECTION_TIMEOUT and
NSAPI_ERROR_NO_CONNECTION when running test wifi_connect_secure_fail
The new configuration make Error history tracking switched off by default and enabled by using the config flag MBED_CONF_PLATFORM_ERROR_HIST_ENABLED.
Config flag MBED_CONF_PLATFORM_ERROR_ALL_THREADS_INFO enables printing info of all threads. This will be turned off by default.
