Increase delta to 500 us. This value is still short enough to detect
incorrect behavior of the sleep_manager_can_deep_sleep_test_check() fun,
but allows the targets with low LP timer accuracy to pass, i.e.
NUCLEO_F429ZI.
There is no problem with this test during the morph, but some issue has been noticed while testing new Jenkins CI in Oulu on NRF52_DK.
I was able to reproduce the issue locally. The difference between morph and local run is that CPU statistics are enabled on morph. This makes the difference and test passes.
The sleep test case perform sleep for 100 us, 200 us, ... ,1000 us in loop (us ticker wakes the board) and verifies if sleep time matches the assumption.
I got the following results:
sleep wake-up after
100 us ~100 us ok
200 us ~200 us ok
300 us ~300 us ok
400 us ~400 us ok
500 us ~14 us (??)
When requested sleep time is equal to 500 us some unexpected interrupt occurs which wakeup the board and force the test to fail.
Register state just after exit from sleep:
Control and State Register: 0x00400000 (ISRPENDING - Interrupt pending flag is set).
NVIC Interrupt Set-pending Register[0]: 0x00000004 (UARTE0_UART0_IRQn) or 0x00000200 (TIMER1_IRQn - timer used by us ticker).
UART interrupt is generated because of green-tea transmission. We know that it is performed while test is executed since we need to wait before going into deep-sleep since otherwise the transmission will be broken. So to take care of UART interrupt we need to wait before sleep test in the same way like it is done in deep-sleep test.
- code refactoring and preparation for enabling DPI/QPI tests
- reduced multiple test count to 4
- use common flash config header for all MX25RXX35F chips
- fix sector erase max time on N25Q128A
Main idea of introduced changes is to ease adding support for new flash chips
Major changes:
- move implementation of all memory chip specific functions to memory config file (no weak functions)
- add support for 1-2-2 write
To handle timer rollovers the test tests-mbed_hal-common_tickers_freq
calls intf->set_interrupt(0). For this to work correctly the ticker
implementation must fire an interrupt on every rollover event though
intf->set_interrupt(0) was called only once. Whether an interrupt will
fire only once or multiple times is undefined behavior which
cannot be relied upon.
To avoid this undefined behavior this patch continually schedules an
interrupt and performs overflow detection on every read. This also
removes the possibility of race conditions due to overflowCounter
incrementing at the wrong time.
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
