fire_interrupt function should be used for events in the past. As we have now
64bit timestamp, we can figure out what is in the past, and ask a target to invoke
an interrupt immediately. The previous attemps in the target HAL tickers were not ideal, as it can wrap around easily (16 or 32 bit counters). This new
functionality should solve this problem.
set_interrupt for tickers in HAL code should not handle anything but the next match interrupt. If it was in the past is handled by the upper layer.
It is possible that we are setting next event to the close future, so once it is set it is already in the past. Therefore we add a check after set interrupt to verify it is in future.
If it is not, we fire interrupt immediately. This results in
two events - first one immediate, correct one. The second one might be scheduled in far future (almost entire ticker range),
that should be discarded.
The specification for the fire_interrupts are:
- should set pending bit for the ticker interrupt (as soon as possible),
the event we are scheduling is already in the past, and we do not want to skip
any events
- no arguments are provided, neither return value, not needed
- ticker should be initialized prior calling this function (no need to check if it is already initialized)
All our targets provide this new functionality, removing old misleading if (timestamp is in the past) checks.

Restore cmsis_nvic (cmsis_nvic.c and cmsis_nvic.h) files for the
implementations which use a mechanism other than the VTOR to set
interrupts. These are vendor specific and were done for M0 devices
which do not have a VTOR.
Note - There were two cmsis_nvic files which did not use the VTOR that
which not restored in this patch. This is because these targets were
not M0 devices and could use the new unified implementation instead.
These files are:
targets\TARGET_ARM_SSG\TARGET_MPS2\TARGET_MPS2_M0P\device\cmsis_nvic.c
targets\TARGET_ONSEMI\TARGET_NCS36510\device\cmsis_nvic.c
Note - cmsis_nvic.c and cmsis_nvic.h were initial removed in
(and restored from) the commit:
b97ffe8fdc -
"CMSIS5: Replace target defined NVIC_Set/GetVector with CMSIS implementation"
There is an easy default implementation of spi_master_block_write that
just calls spi_master_write in a loop, so the default implementation
of spi_master_block_write has been added to all targets.
Affected boards: NRF51_DK, NRF52_DK, Beetle. This change is temporary and
will be overwritten by RTX update. It's necessary for the boards to pass
updated tests.
s140 headers renamed form ble_* to nrf_ble_*,
Removed s130 and s132 headers named form ble_*
(Them had been added by #2ff572682798562e812015dc775b5896e0fda5a4)
Headers inclusinons were changed in order to meet above changes.
Revrted bad change in us_ticker.c:
use __disable_irq lock instead of core_util_critical_section_enter lock
for setting rtc1 tick for systick emulation as was good before.
HAL driver: Add changes from needad for nrf52840 support
us_ticker, spi, sleep, serial, pwmout, pinmap, object, i2c, gpio, analogin
Add compatibility patches for:
- SoftDevice headers renamed (redirec by a few h files)
- sdk configuration (redirect by sdk_config.h files)
- renaming of func in softdevice handler module
This removes the duplicate header files from the build. We were getting
lucky on most invocations of `mbed compile` in that these headers were
searched for after some others, but not when exporting to uvision.
