- Move back the 16/32bit timer initialization in HAL_InitTick() and not in us_ticker_init()
- Use ticker_read_us() and us_ticker_read() in HAL_GetTick() to fix potential overflow issue with the 16bit timer
==> These corrections allow timer, rtc, sleep, tick tests to PASS
The TEST_SKIP and TEST_SKIP_UNLESS macros (w/ and w/o messages) allow the test
to skip the test case execution from the point the macro was called (without
failing the test).
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).
- RTC_SSR for the subseconds
- RTC_TR for the time
- RTC_DR for the date
These registers were accessed through shadow registers which are synchronized with PCLK1 (APB1 clock).
They are now accessed directly in order to avoid waiting for the synchronization duration.
For ABP: First call to connect() or connect(params) will return LORAWAN_STATUS_OK
and a CONNECTED event will be sent. Any subsequent call will return
LORAWAN_STATUS_ALREADY_CONNECTED (posix EISCONN) and no event is generated.
FOR OTAA: First call to connect() or connect(params) will return LORAWAN_STATUS_CONNECT_IN_PROGRESS
and a CONNECTED event will be sent whenever the JoinAccept is received. If the application
calls connect again before receiving the CONNECTED event, LORAWAN_STATUS_BUSY will be returned.
After the CONNECTED event is dispatched, any subsequent call to connect() or connect(params) API
will be returned with LORWAN_STATUS_ALREADY_CONNECTED.
No new parameters are accepted after the first call. The application must disconnect before making
a connect() call with new parameters.
This is a remedy for the issue #7230.
While the device is joining, LORAWAN_STATUS_CONNECT_IN_PROGRESS is returned.
However, if the device is already joined, we will return LORAWAN_STATUS_ALREADY_CONNECTED.

This change allows existing source code with this naming
convention (e.g. my company's) to be used in mbed.os projects.
