Fixed by zeroing the memory. A more "c++ correct" approach
may be to add an additional op for equality, and use the "=="
operator on the F type in the generate function. But this adds
the requirement that F supports equality.
Rather than Unlocking flash during flash object creation, and leaving
the flash possibly continuously unlocked a(s object might bever be freed),
we decide to Unlock then Lock again at each erase or program call.
Fixing regression introduced in commit
"Ticker: add fire interrupt now function".
In above mentioned commit, the management of timestamp being in the past
has been moved to higher layer (hal/mbed_ticker_api.c), but the reset of
oc_int was missing when implementing the new us_ticker_fire_interrupt
function - which is fixed now.
After reset the MCR register content needs to be restored so we're
introducing the can_registers_init function to be called at the first
init stage, but also after reset. We also store the can frequency to
go through the initialisation phase again.
In order to apply the same mode in case of reset, we store the current
requested mode in the HAL structure.
To make storage in a single place, we also change can_monitor to call
can_mode function as they actually acting on same registers.
Instead of a static object, this will make driver
instantiation more robust and allow to re-use init
configuration on a need basis.
The CANName struct member is actually the CAN registers base address,
which is now available in the CanHandle.Instance field, so we don't need
CANName anymore.
Make calls to cmsis-os to get thread state, stack size, and max stack
usage rather than accessing internal RTX data directly. Wrap RTX5
specific code in OS_BACKEND_RTX5.
Also refactor the code to use mbed types rather than RTX types:
os_timer_t -> mbed_rtos_storage_timer_t
os_event_flags_t -> mbed_rtos_storage_event_flags_t
osRtxMutex_t -> mbed_rtos_storage_thread_t
Since mbed-os 5.4.3, something increased foot print of mbed-os and the applications that were barely fitting in started to spill.
IAR toolchain for LPC176x target family is set to use 2 RAM regions (32K each). RAM region
2 is being used for ETH/USB and 1 is being used for vector table, stack/heap/static data.
In this commit we have decreased heap size allocation from 8K to 7K so that the is more room for stack and static data.
If NVIC_NUM_VECTORS is larger than the space allocated by the vector
table in ram (__ram_vector_table_size__) then the call to mbed_cpy_nvic
during boot will corrupt valid data, which can lead to a crash. This
patch fixes the declared number of vectors on the KL27Z, KL43Z and
KL82Z to fix this crash.
To allow components with a simple need to schedule a few events to not
have to create their own threads, with all the associated memory
overhead, add 2 central calls to get shared normal and an
interrupt-deferral event queues, each dispatched on their own shared
threads.
For non-RTOS systems, just the normal event queue is provided, and the
application would have to dispatch this itself. This
application-dispatch is also available via a config option, to
potentially save memory by reusing the main thread.
Possible future improvement: the ability for separate components to
request a minimum stack size, and have the JSON combine these requests.
(Analogous tooling has already been mooted for mbed TLS config options
like key size).
Update directory structure to include RTX for only cortex targets, and
for all cortex targets. This patch accomplishes this by moving mbed-os
specific RTX files and RTX itself into rtos/TARGET_CORTEX along with
removing TARGET_CORTEX_M from the RTX5 directory.
The old directory structure:
rtos/rtx5/<mbed-os specific RTX files>
rtos/rtx5/TARGET_CORTEX_M/*
rtos/rtx4/*
rtos/<mbed-os specific RTX files>
Is re-arranged to:
rtos/TARGET_CORTEX/rtx5/*
rtos/TARGET_CORTEX/rtx4/*
rtos/TARGET_CORTEX/<mbed-os specific rtx files>
This both encapsulates RTX code more cleanly and makes it easier to
experiment with non-cortex cmsis-os2 backends, such as a posix
based cmsis-os2 backend.
Note - A potentially better name for the CORTEX_M directory would be
something like FEATURE_RTX5 since this directory only contains RTX5
related files. This cannot be done because there is not an easy way
to turn this feature on, since it cannot be done from mbed_lib.json.
