In M2351 SPDMC (SMCC) test, it boots from secure code to non-secure bootloader, and finally
to non-secure test code itself. The boot sequence will takes longer than usual. In test
initiation, host will send sync signal 1s after reset device. But due to the longer boot
sequence, test code in device can miss the signal. We enlarge the reset idle time to fix
the issue.
On ARMC6 with optimization level "-Os", the two functions NVIC_SetVector/NVIC_GetVector
will be translated to illegal instruction for trapping due to NVIC_FLASH_VECTOR_ADDRESS
defined as direct 0. Fixed by defining NVIC_FLASH_VECTOR_ADDRESS as a symbol instead to
avoid such optimization error.
By default, FLASH_SIZE should be read from HW.
In case this is not the case, we define it here, as the size of FLASH
that is available to the application running on M4.
the flash is shared and split between cortex-M4 that
runs (mbed-os) application and the cortex-M0+ that
runs the BLE firmware.
The 512K allocated to the application was a
conservative that can now be updated.
With recent up-to-date BLE firmware flashed @ 0x080CB000,
there should be 812K available to application.
But there are boards out there that don't have an up-to-date
firmware, so we're keeping an intermediate, safer,
application size of 768K.
Change the heuristic for selection of CMSE in the tools python, so that
a non-TrustZone ARMv8 build can happen.
Ideally we would have more direct flagging in the targets, but this
refines the heuristic so the necessary behaviour can be easily
achieved.
* DOMAIN_NS=1 is based purely on the `-NS` suffix on the core name.
* Enabling CMSE in the compiler and outputting a secure import library
is now enabled when the core doesn't have an `-NS` suffix by either
the target label `TFM` being present or the flag `trustzone` being set.
This covers the existing ARMv8-M behaviour - TF-M builds have the TFM
label, as per its documentation; M2351 secure builds have no explicit
flagging, so we ensure that the M2351_NS target has the trustzone flag
set, and the out-of-tree secure target inherits that.
Some Nuvoton targets support DEVICE_FLASH but their corresponding COMPONENT_FLASHIAP
supports are not enabled. Enable them:
NUMAKER_PFM_M453
NUMAKER_PFM_M2351
Reimplement atomic code in inline assembly. This can improve
optimisation, and avoids potential architectural problems with using
LDREX/STREX intrinsics.
API further extended:
* Bitwise operations (fetch_and/fetch_or/fetch_xor)
* fetch_add and fetch_sub (like incr/decr, but returning old value -
aligning with C++11)
* compare_exchange_weak
* Explicit memory order specification
* Basic freestanding template overloads for C++
This gives our existing C implementation essentially all the functionality
needed by C++11.
An actual Atomic<T> template based upon these C functions could follow.
Purposes:
* Remove MbedOS-specific code from system_psoc6_{cm4,cm0plus}.c
to simplify updates to new PDL version (startup code is part of PDL).
* Unify mbed_sdk_init initialization sequence for both CPU cores.
This change is non-functional, sequence itself is not changed for any
of the PSoC 6 M4/M0 PSA/non-PSA targets.
According to their cmsis.h, FPU is present, so change targets.json to
use it.
* ARM_MPS2_M4: already was Cortex-M4F
* ARM_MPS2_M7: Cortex-M7 -> M7FD
* FVP_MPS2_M4: Cortex-M4 -> M4F
* FVP_MPS2_M7: Cortex-M7 -> M7FD
If they do not in fact have FPU, then cmsis.h should be modified to set
`__FPU_PRESENT` to 0. This will currently cause compilation problems
with ARMC6, but I'll be submitting a fix for that.
On NUC472, on wake-up from power-down mode, we may meet hard fault or some other
unknown error. Before its cause is found, we enter idle mode instead for a workaround.
To simulate power-down mode with idle mode, we also disable us_ticker during
power-down period.
PDL Flash API requires that the data buffer is 32-bit aligned, otherwise
programming can hung. Buffer declared as uint8_t array is not always
properly aligned, e.g. with gcc 6 when -Os option is used.
Flash driver 3.30:
Moved ipcWaitMessageStc structure to the RAM section called ".cy_sharedmem"
Added support Secure Boot devices
Moved CY_FLASH_EFFECTIVE_PAGE_SIZE to flash_api.c (the macro is Mbed specific).
GeneratedSource folders are BSP specific. No parts of the kit BSP can be reused
as generic chip support package. Remove TARGET_CY8C62XX directory,
and use flat BSP inheritance model:
MCU_PSOC6 -> MCU_PSOC6_M4 -> CY8CKIT_062_WIFI_BT
MCU_PSOC6 -> MCU_PSOC6_M0 -> CY8CKIT_062_WIFI_BT_M0

These file changes provide small fixes for various targets
on MPS2 platform in order to work properly and pass all
Greentea test cases. The __initial_sp has been explicitly set
in the targets' startup files, and also INITIAL_SP has been
given a different value. The values have been extracted from
the specific targets' Application Note documentation.
Affected targets are: ARM_MPS2_M0, ARM_MPS2_M0P, ARM_MPS2_M3,
ARM_MPS2_M4 and ARM_MPS2_M7.

Spotted in compiler warnings - code was trying to access a non-existent
second security control block, rather than access the settings for the
second APB bridge in the first and only security control block.
The hal code for this target uses "const volatile" types inside of
structs, which are non-trivially copyable in clang (used by ARMC6). This
causes the build to fail.
Here's the commit that changed this in clang:
a3d727ba77
It seems this was reverteed some time ago in clang, but ARMC6 may not
be up to date.
To have the flexibilty in application; to use any of the section
(data/bss/heap) without updating linker script in every use case,
following decisions are made:
1. Fixed size and small sections moved to SRAM2 (32K)
Vectors
Crash data
Remaining section - RW / ZI
2. Large memory space should be used for variable sections
RW/ZI
Heap - (Minimum - 0x12000)
Stack - At bottom
Please note the heap address of the both the banks must not be contigious else
GCC considers it to be single memory bank and does allocation across the banks,
which might result into hard-fault

Heap is moved to the end of both sections as GCC allocates till 4K boundary,
if end of heap is not aligned to 4K, that chunk of memory will go unutilized
