Add 2 targets for DISCO_H747I dualcore:
* DISCO_H747I -> for CM7 core
* DISCO_H747I_CM4 -> for CM4 core
Current restrictions:
* TICKLESS deactivated
* DeepSleep not supported (DeepSleep wrapped to sleep)
Warning: use of the same IP (example I2C1) by both core at the same time is not prevented,
but is strongly not recommended.
Some Hardware Semaphore are use for common IP, to manage concurrent access by both cores: Flash, GPIO, RCC.
Warning: Drag and drop of binary to DISCO_H747I will flash CM7.
In order to flash CM4, one can use STM32 CubeProgrammer tool.
The cyhal_spi_send api was changed to read and discard a byte on every
send operation (at the protocol level all SPI transfers are bidirectional).
This means that to achieve a truly bidirectional transfer, the
cyhal_spi_transfer API must be called (as opposed to a write followed
by a read).
Earlier changes introduced a change to default Arm C6, which does not compile the micro library which is based on Mbed 2. This change fixes the compiler version for NRF51_MICROBIT devices.
The QSPI spec allows alt to be any size that is a multiple of the
number of data lines. For example, Micron's N25Q128A uses only a
single alt cycle for all read modes (1, 2, or 4 bits depending on
how many data lines are in use).
- Fixed miscalculation in SPI frequency setup (divider value).
- Added possibility to set up SCK line as NC (usable when SPI peripheral
is used to handle non-SPI protocols.
- Fixed handlingh of 16-bit (and other >8 bit) transfers.

Reasons to remove TRNG support:
1. M252 just has 32KiB SRAM and cannot afford mbedtls application.
2. Implementing TRNG HAL with PRNG H/W has security concern.
Without free-up of peripheral pins, peripheral pins of the same peripheral may
share by multiple ports after port iteration, and this peripheral may fail with
pin interference.
In Nuvoton, only new-design chips support GPIO input pull-high/pull-low modes.
Targets not supporting this feature are listed below:
- NUMAKER_PFM_NANO130
- NUMAKER_PFM_NUC472
- NUMAKER_PFM_M453
Fix logic error on replying NACK at the end of transfer.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-i2c/
i2c - test single byte read i2c API.
Better IP initialization sequence:
1. Configure IP pins
2. Select IP clock source and then enable it
3. Reset the IP (SYS_ResetModule)
NOTE1: IP reset takes effect regardless of IP clock. So it doesn't matter if
IP clock enable is before IP reset.
NOTE2: Non-configured pins may disturb IP's state, so IP pinout first and then
IP reset.
NOTE3: IP reset at the end of IP initialization sequence can cover unexpected
situation.
On Nuvoton targets, lp_ticker_set_interrupt(...) needs around 3 lp-ticker
ticks to take effect. It may miss when current tick and match tick are very
close (see hal/LowPowerTickerWrapper.cpp). Enlarge LPTICKER_DELAY_TICKS to
4 from 3 to address this boundary case.
Without this override, mpu hal will require 5 mpu regions which exceed 4 mpu
regions supported by M252 (see hal/mpu/mbed_mpu_v8m.c). In this scenario,
we will hit assert error but we actually meet stack overrun first due to just
0x400 bytes for emitting error message. The issue doesn’t occur on other
targets such as M487 because it has 8 mpu regions.
static_memory_defines controls the macro MBED_RAM_START AND MBED_RAM_SIZE
when nrf52840 to use softdevice, it need MBED_RAM_START to set the true application ram start
default static_memory_defines is true, so just remove NRF52840 and NRF52832's set
Remove some (Cypress-proprietary) BSP interfaces and hardware initialization
from the BSPs which is better implemented by a library or application firmware.
Move some remaining functionality from common to the individual targets.
Don't malloc during wifi initialization, as that could cause double allocation in some cases.
The thread stack will be allocated by cy_rtos_thread_start if necessary.
- Add const and static qualifiers in places where they are
applicable but missing
- Remove headers for drivers that aren't implemented yet
- Misc minor bugfixes
Keep vector table and crash data ram in 0x20000000 for
tests-mbed_platform-crash_reporting test.
Move the rest in RAM (0x24000000). This is needed for ethernet and allows
user to use more RAM (512k).

NOTE1: USB UART is partitioned for non-secure world. Secure world still can share
it with limit that its interrupt cannot use in secure world.
NOTE2: In secure world, USB UART is only for Greentea and STDIO. Developers shouldn't
use it for other purposes.
Support secure/non-secure combined build for non-PSA target:
1. In secure post-build, deliver built secure image to TARGET_NU_PREBUILD_SECURE
directory which is to combine later.
2. In non-secure post-build, merge non-secure image with secure image saved in
TARGET_NU_PREBUILD_SECURE directory.
3. In non-secure post-build, user can also drop pre-built secure image saved in
TARGET_NU_PREBUILD_SECURE directory and provide its own by adding the line below
in mbed_app.json:
"target.extra_labels_remove": ["NU_PREBUILD_SECURE"]
1. Create a private target name NU_PFM_M2351_CM which stands for the
NuMaker-PFM-M2351 board and is to be extended.
2. NU_PFM_M2351_NPSA_S/NS target names for non-PSA secure/non-secure targets
respectively.
3. The original target name NUMAKER_PFM_M2351 is recycled and cannot be used.
Use NU_PFM_M2351_S/NS for non-PSA secure/non-secure targets instead.
NOTE: Target name doesn't follow the rule below because online database has
limit of max 20 chars:
NUMAKER_PFM_M2351_PSA/NOPSA_S/NS
Instead, it has the rule:
NU_PFM_M2351_[NPSA_]S/NS
NU_PFM_M2351_S/NS for PSA targets. This is to be consistent with current
PSA target naming. So the resolved target names are:
NU_PFM_M2351_S : PSA secure target
NU_PFM_M2351_NS : PSA non-secure target
NU_PFM_M2351_NPSA_S : Non-PSA secure target
NU_PFM_M2351_NPSA_NS : Non-PSA non-secure target
We should not block in case the UART is busy transmitting. The
API has been updated to check the status of all UART's and return
1 in case any of them is busy transmitting.

The code checks if any of the UART's is still transmitting.
If so then prevent from entering deepsleep

Fixed HAL API implementation for InterruptIn:
- Interrupt was not enabled by default after configuration as it should be.
- Interrupt-to-object linking was not handled properly.
Removed private TODO file.
Fixed cmsis.h so that renaming of CS and DIR_H is not necessary any more.
Leave pinmap.h unchanged although it should include stdint.h
Moved stdint.h to PinNames.h instead, where it is also used.
Reworked system startup (clock configuration) to be more flexible
(different clock sources for MCLK and SMCLK, configurable clock dividers).
Fixed Copyright headers
Changed default clock settings for MSP432 Launchpad to
MCLK 48 MHz (HFXT) and SMCLK 24 MHz (HFXT)
Remove mbed_rtx.h
Added common mbed_rtx.h file (merge with lastest master)
Added support for IAR toolchain
Fixed some astyle problems.
Added support for ARM C5/C6 toolchains
Small changes to us_ticker implementation after port testing.
Changed default clock configuration to DCO (MCLK 48MHz, SMCLK 24MHz).
De-configured the LFXT crysal, because this made the system_reset() test to time out.
Removed MPU from device_has list. Changed clock source to HFXT.
Reworked startup_msp432p401r.c -> now only one startup file for all compilers.
Changed all linker scripts to delete VECTORS stuff (not needed).
Moved position of MSP432 in targets.json so TI stuff is in one block.

This test requires total latency (tot = h/w + s/w) (wakeup from deepsleep) be
under 1ms. To check the issue, measure total latency on Nuvoton targets:
TARGET EXP(us) EXP+TOL(us) ACT(us)
NANO130 42000 43000 42939
NUC472 42000 43000 42236
M453 42000 43000 43274
M487 42000 43000 42877
M2351 42000 43000 43213
Checking h/w spec, h/w latency (wakeup time from normal power-down mode) on
M487/M2351 is just 1us (n/a on other targets). S/W latency plays the major
part here.
S/W latency relies on system performance. On Nuvoton targets, 'LPTICKER_DELAY_TICKS'
possibly complicates the test. Anyway, to pass the test, add extra 1ms latency
(deep-sleep-latency) in targets.json for Nuvoton targets.
On Nuvoton targets, lp_ticker_set_interrupt(...) needs around 3 lp-ticker
ticks to take effect. It may miss when current tick and match tick are very
close (see hal/LowPowerTickerWrapper.cpp). Enlarge LPTICKER_DELAY_TICKS to
4 from 3 to address this boundary case.
