Workaround a bug where the boot stack size configuration option is not
passed on to armlink, the Arm Compiler's linker. Prefer
MBED_CONF_TARGET_BOOT_STACK_SIZE if present, as this is what the
configuration system should provide. Fall back to MBED_BOOT_STACK_SIZE
if MBED_CONF_TARGET_BOOT_STACK_SIZE is not defined, as in the case of
buggy tools. If both MBED_CONF_TARGET_BOOT_STACK_SIZE and
MBED_BOOT_STACK_SIZE are not defined, then we fall back to a hard-coded
value provided by the linkerscript. See
https://github.com/ARMmbed/mbed-os/issues/13474 for more information.
To allow overriding of the boot stack size from the Mbed configuration
system, consistently use MBED_CONF_TARGET_BOOT_STACK_SIZE rather than
MBED_BOOT_STACK_SIZE.
Fixes#10319
Add a "used" attribute to __vector_handlers to fix ARMC6 build with
the "-flto" flag.
(Error: L6236E: No section matches selector - no section to be FIRST/LAST.)
This attribute, attached to a function/variable, means that code must be emitted
for the function even if it appears that the function is not referenced.
On IAR, configure heap to 1KiB at a minimum and expandable, dependent on available SRAM. This requires IAR 8.x.
Support targets:
- NUMAKER_PFM_NUC472 w/ and w/o XRAM
- NUMAKER_PFM_M453
- NUMAKER_PFM_M487/NUMAKER_IOT_M487
- NUMAKER_IOT_M263A
- NUMAKER_M252KG
Instead of user defined symbols in assembly files or C files,
use linker scripts to add heap and stack - this is inconsistent
with ARM std linker scripts
--legacyalign, --no_legacyalign are deprecated from ARMC6 compiler, in order to
remove deprecated flags all linker files (GCC and IAR as well to have uniformity)
should strictly align to 8-byte boundary
1. With mbed OS 5, mbed_sdk_init() is ensured to call before C++ global object constructor.
2. Refine startup file with GCC_ARM toolchain related to this modification.
1. Add targets into build_travis.py and tests.py.
2. Add target SPI pins into SPI SD test samples.
3. Rename target TOOLCHAIN_GCC_ARM/retarget.c to avoid name collision of compiled retarget.o with platform/retargets.cpp.
1. Move M451Series.h to device.
2. Move StdDriver to device.
3. Move TOOLCHAIN_* to device.
4. Move cmsis*, startup_M451Series.c, and system_M451Series.c/h to device.
