Some Cortex-M0 devices, such as the nrf51, don't have the SysTick.
Instead, these targets use a software interrupt to simulate SysTick.
Add the hooks in the tickless code to support these devices. Targets
which do not have SysTick should now define NO_SYSTICK in targets.json
and implement mbed_get_m0_tick_irqn to add os suport.
This patch also removes os tick handling from the existing devices
(nrf51) since this is now handled in common code.
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.
Adding flash API support to STM32F7 family. The code is derived from
F4 family one. The memory topology is described in flash_data.h files
and the flash_api.c implementation manages the 2 possible memory types (1
or 2 banks).
Users of FlashIAP usually get the minimum programable size
by calling flash.get_page_size(), so let's return the minimum
to allows a most efficient usage of flash.
For F4 devices, this is 1 byte.
For L0 and L1 devices, this is a word (4 bytes).
For L4 devices, this is a double word (8 bytes).
First add the flash_data.h that describe the flash memory topology,
and also activate FLASH support for the corresponding targets.
This is a 1,5MB flash memory device which contains 15 sectors, where
sectors 12 to 15 are 128KB sectors. So flash_api.c needed has been
updated to differentiate between this flash memory and the 2MB ones
by checking existence of sector 16 instead of sector 12.
UBLOX_ODIN_EVK_W2 is missing the abstract button definitions originally
introduced with PR https://github.com/ARMmbed/mbed-os/pull/4249.
Fix two tab to spaces issues on the go as well.
It is required to enable AFIO clock before using __HAL_AFIO_REMAP_xy
macros, which was missing here. Without clocks enable, the remap
actually doesn't occur. This would possibly cause some PIOs (part of
PB_3, PB_4, PA_13, PA_14, PA_15) to not behave as expected.
In most cases AFIO clock was enabled in stm_pin_SetAFPin function, so
that this bug was not visible. But there were few cases left were
stm_pin_DisconnectDebug would be called first. A typical case was
with GCC_ARM in case a DigitalInOut variable is declared as global.
