As the timer code became more generic, coping with initialization on
demand, and variable width and speed us_ticker_api implementations,
wait_us has gradually gotten slower and slower.
Some platforms have reportedly seen overhead of wait_us() increase from
10µs to 30µs. These changes should fully reverse that drop, and even
make it better than ever.
Add fast paths for platforms that provide compile-time information about
us_ticker. Speed and code size is improved further if:
* Timer has >= 2^32 microsecond range, or better still is 32-bit 1MHz.
* Platform implements us_ticker_read() as a macro
* Timer is initialised at boot, rather than first use
The latter initialisation option is the default for STM, as this has
always been the case.
Running PowerShell script on some windows machines is blocked.
To avoid this problem script was replace by the code run directly in PowerShell console.
With the DEEP_SLEEP_TEST_CHECK_WAIT_DELTA_US increased,
we now have TEST_ASSERT_UINT64_WITHIN(delta=1000, expected=1000, actual=1000)
so this assertion needed to be updated.
What we need is the deep sleep to be enabled after the programed interrupt
has fired and before a 2ms timeout expiration, which means >= 1000 and < 2000.
Changes:
- restore the original form of setup/teardown handlers,
- test_lock_unlock_test_check(): do not use common ticker layer (Timer, Timeout). Use only ticker HAL layer.
- Increase DEEP_SLEEP_TEST_CHECK_WAIT_DELTA_US delta.
In particular and as kindly suggested by Przemec S. :
1. Add setup/teardown handler’s for all cases. This disables sys-tick,
so there should be no unexpected lp ticker interrupt scheduling.
2. Modify setup/teardown handler’s: remove suspension of lp/us tickers,
so they can count as this is required by test_lock_unlock_test_check test
case.
3. Use TEST_ASSERT_TRUE(sleep_manager_can_deep_sleep_test_check()) after
setting interrupt to cope with STM specific handling (CMPOK interrupt with
deep-sleep locked). This performs wait only if needed and will not affect
other targets which do not need extra wait.
4. Move sleep_manager_lock_deep_sleep() after TEST_ASSERT_TRUE(sleep_manager_can_deep_sleep_test_check())
5. Use TEST_ASSERT_TRUE(sleep_manager_can_deep_sleep_test_check()) in
test_lock_unlock_test_check to let lower layers manage deep sleep.
As the build tool in mbed-os 5.13 cannot appropriately deal with a segmented
bootloader when combining it with an application, this commit adjusts the
size reserved for interrupts (via the linker file) to avoid a bootloader
segmentation due to an unpopulated ROM area.
The microcontroller has a total of 60 vector interrupts + 16 exception
handlers. The allocated ROM flash for interrupts should be (60 + 16) x word
size in bytes = 76 x 4 = 304 = 0x130.
This commit changes the interrupt reserved space from 0x140 to 0x130.
Building binaries with MicroLib and Arm compiler 6 has been failing
because of a bug in Arm compiler 6. The compiler introduces a
symbol, `__scanf_mbtowc`, which is not present in MicroLib C library.
The present commit adds a weak reference to the symbol to allow a
successful linkage. This is a temporary fix until the bug in the
compiler is fixed. It should be removed after the compiler bug is fixed.
M23 doesn't implement Main Extension. So like M0/M0+, these registers HFSR/
MMFSR/BFSR/UFSR/DFSR are not present on M23. Remove access to them in mbed
fault handler for M23 targets.
Replace the hardcoded value calculation of the memory pool block size
with the RTX preprocessor macro (via a shim layer).
This is in preparation for the replacement of the direct access of RTX
functionalities in Mbed OS with an access via CMSIS.
