Make the option positively named, and as it is a platform config
option make sure it only affects platform code.
HAL functions still remain available even if platform is told not
to use them.
MPU lock under- or overflow is not a likely random runtime failure - it
will be a mismatched lock/unlock programming error, so should be
detected during development. Make the checks asserts so they can be
left out from release builds. MBED_ASSERT is also a bit smaller than
MBED_ERROR in develop builds.
Make the following changes:
-Allow a vector specific ARM MPU driver by defining MBED_MPU_CUSTOM
-Allow ROM address to be configured for ARMv7-M devices by
setting the define MBED_MPU_ROM_END
-Add ROM write protection
-Add new functions and lock
-enable at boot
-disable during flash programming
Rename MpuXnLock to ScopedMpuXnLock so it has the same naming
convention as ScopedMutexLock. Also make this class inherit from
NonCopyable to prevent misuse.
Enable the MPU as part of the boot sequence and disable it before
starting a new application. Also add reference counted MPU lock and
unlock functions to allow code to execute from ram when necessary.
Adding new modules inside the namespace could be breaking change for existing code base
hence add `using namespace::class` for classes newly added to mbed namespace to maintian
backwards compatibility.
MBED_NO_GLOBAL_USING_DIRECTIVE is added to remove auto-addition of namespace
Macro guard `MBED_NO_GLOBAL_USING_DIRECTIVE` is added around namespace, to avoid
polluting users namespace.
SocketStats Class is added to collect and provide the statistics information.
In this phase only socket information is collected and max sockets that can
be recorded at any time are configurable through 'MBED_CONF_NSAPI_SOCKET_STATS_MAX_COUNT'
Network statistics can be enabled through a macro MBED_NW_STATS_ENABLED
More information on design is captured in #8743
Implement the following:
KVStore base class
TDBStore class
FileSystemStore class
SecureStore class
Global APIs
Configuration framework
Design documentation
Moved "bootloader_not_supported" check to where it was and handle that exception at only one place.
Removed ram/rom size info for realtek from targets.json. THe info we have is not correct.
was Not handling config exceptions from regions and ram_regions property
adding rom-ram info for REALTEK_RTL8195AM
Modify the implementation of CThunk so it does not execute from ram.
Instead is uses an array of functions in flash which can be allocated
as a thunk. The number of CThunks that can be used by an application
can be configured with MBED_CONF_PLATFORM_CTHUNK_COUNT_MAX.
The issue is that the process_oob check would only return immediately
if no data at all on entry, or when receiving a known OOB. Any other
line noise or unknown OOBs could lead to a timeout delay - read the
noise or unknown OOB then timeout waiting for another line of input.
This revised version modifies the parser to recheck readable after each
line end when only looking for OOBs, so it can immediate exit.
Save some ROM space by putting MBED_NORETURN attributes on error
functions and failed asserts.
mbed_error was documented as returning an error code. It never
actually could return, so documentation updated, but return type
kept.
Various fixes in preparation for making sure error calls do not return.
* Clear out handle_error's use of error_in_progress as a sort of spin
lock; this is most likely to deadlock if ever activated, and conflicts
with error's use of error_in_progress. Use a normal critical section lock.
* Make error use same mbed_halt_system helper as mbed_error.
* Make error's recursion check avoid print and proceed to halt, rather
than returning.
* Make mbed_error use error_in_progress to avoid recursion in same way
as error() does.
* Give mbed_halt_system its own recursion check in case of error in
mbed_die - give it a simple fallback.
* Make the in_progress things properly atomic, just in case.
An atomic flag primitive is sometimes wanted, and it is cumbersome to
create it from the compare-and-swap operation - cumbersome enough that
people often don't bother.
Put in a core_util_atomic_flag that follows the C11/C++11 atomic_flag
API, such that it could be mapped to it with #define later.
API's updated as:
1. wait(float) calls wait_ms for >=0.01s and not in interrupt, else wait_us.
2. wait_ms() is just the thread sleep and doesn't lock hardware sleep.
In order to have backward compatibility, if used in ISR `wait_us` is
called if MBED_TRAP_ERRORS_ENABLED is false
3. wait_us() is a ticker-based wait, always spinning.
