In case of prescaler_rank was 0, a -1 index was being used,
which resulted in initialization of the Init.BaudRatePrescaler with
random values.
Now let's better check index and avoid -1 operation, so that prescaler_rank
can be only from 0 to "last_index".
In sendto(), memory allocation failures were mistakenly being treated as
would blocks (assumption was that the device might be able to recover).
However, that put the blocking socket into deep sleep and there was no mechanism to wake it up
ever again. Somehow that got slipped through testing. Fixed in this amenment
MBED_CONF_PLATFORM_STDIO_CONVERT_NEWLINES was not used in mbed_error_vfprintf causing wrong behavior when the option was selected (no new line is some terminals like putty).
As a result of major overhaul in Nanostack generally for socket API and especially
for TCP, the adaptation layer for mbed-OS is being upgraded.
Previously, as nanostack was not able to provide receive queue, adaptation layer had been
faking it. Now with Stream Socket by default Nanostack provides 2K receive queue and 2K send queue.
Receive queue size can be changed using setsockopt(). Batre metal nanostack would not provide with any
receive queues with Datagram Socket, however in this adaptation layer we introduce a 2K receive queue size
for the Datagram Socket as well.
Layer state machine handling is polished to ensure robustness.
::socket_connect() will can return 2 new error codes now. NSAPI_ERROR_ALREADY (like posix EALREADY) in case
if the connection is in progress or NSAPI_ERROR_IS_CONNECTED (like posix EISCONN) if already connected.
NSAPI_ERROR_WOULDBLOCK is now mapped directly to nanostack NS_WOULDBLOCK.
NanostackLockGaurd class is introduced which enables us to claim and release mutex using RAII style.
Add MBED_APP_START and MBED_APP_SIZE to the Odin's linker script
so the start and size of an image can be specified. This allows the
ROM to be split into a bootloader region and an application region.
Add MBED_APP_START and MBED_APP_SIZE to the stm32f429's linker script
so the start and size of an image can be specified. This allows the
ROM to be split into a bootloader region and an application region.
Add MBED_APP_START and MBED_APP_SIZE to the K64F's linker script
so the start and size of an image can be specified. This allows the
ROM to be split into a bootloader region and an application region.
Before, `make_gcc_arm` would export a makefile with both linker flags in
the `$(LD)` make variable and the `$(LD_FLAGS)` make variable. This only
affected GCC based makefiles, as the `$(LD)` make variable would only
contain the linker for both ARMC5 and IAR. This patch enforces the
`$(LD)` behavior of ARMC5 and IAR on all of the compilers by truncating
`$(LD)` to just the command
For toolchains that do not implicitly run the C pre-processor on their
linker scripts the toolchain is expected to define a `preproc`
attribute. The Makefiles then pick up on this attribute and add another
rule for pre-processing the linker script automatically.
This allows us to define parts of the linker script outside of the
linker script itself. In particular, we are interested in restricting
ROM to a subsection.
The field device_name is intended to match that of a target in a
device family pack. Remove this field for devices which do not have
a pack. Fix the name for devices that have the name incorrect. Update
IAR definitions for device which no longer have a device_name but
still need to have support for the IAR exporter.
The worker_result variable was not guaranteed to have a `'result'` or
`'reason'` key and accessing them before testing for them could result
in an error when they are not provided. This patch changes the checks to
prevent check for their existence before accessing them.
* Adding Cortex-A support for gnuarmeclipse
* Preventing '-mthumb' from being added to Cortex-A builds.
Previously, both '-mthumb' and '-marm' were being supplied to the
compiler (in that order). Because '-marm' came last, the compiler
respected this option. This change makes it so '-mthumb' is added for
all 'Cortex-M' targets only.
* Renaming to capital .S for Eclipse compatibility
With the RTOS, the STACK_SIZE specified here is unrelated to the stack
size available for the main thread (that runs pre_main). Save memory by
reducing the stack size to a more reasonable amount.
On uVisor, HEAP_SIZE is both a minimum available and maximum available
heap size. The heap can't grow beyond the end of the heap into the
neighboring stack. On all uVisor-supported platforms, guarantee at least
0x6000 bytes of heap space. This increases the portability of uVisor
applications as the memory available for legacy heap allocations is
guaranteed. This helps to avoid out of memory errors on platforms that
were previously guaranteeing less memory.
