I modified the _page_program() because when the request of the size exceeding the maximum size(256 byte) per one writing of Flash recieved, it was not able to loop the writing with sifting the address every 256 byte.
Also I modified the return value of flash_get_page_size() because I found that the minimum size per one writing of Flash is 1 byte by reviewing Flash spec.
"FLASH_PAGE_SIZE" macro's value is remain 256, it doesn't be used at flash_get_page_size(), used at _page_program() for refferencing of the maximum page size.
Although other venders implement this feature by using RTC, in my H/W(RZ_A1), I cannot use RTC because it does not satisfy the spec of LP Ticker (ms order and low frequency between 8 KHz and 64 KHz).
Therefore I implemented this feature by creating 1024 division by MTU2(Multi function Timer pulse Unit 2) in order to satisfy this spec.
As a result of investigating, the most unaffected channel among MTU2 placed on GR-PEACH and GR-LYCHEE was channel 3, so I use channel 3 for this feature.
- mbed_drv_cfg.h
I added a macro of MTU2 channel to this file for commonalizing code for GR-PEACH and GR-LYCHEE, and referenced it's macro at us_ticker.c.
- targets.json
I added a macro for enabling LP Ticker.
- mtu2.c mtu2.h
I defined fuction of MTU2's clock supply and stop.
Because MTU2 is utilized by pwm driver too, those function were referenced at lp_ticker driver and pwm driver.
- lp_ticker.c lp_ticker_init()
In order to satisfy the LP Ticker spec, I implemented by creating 1024 division by MTU2.
When an interrupt is required, it will be set with ticker_set_interrupt().
- lp_ticker.c lp_ticker_free()
This function stops the counting and powerdown the lp_ticker.
- lp_ticker.c lp_read()
This function returns the timer counter of MTU2.
- lp_ticker.c lp_ticker_set_interrupt()
In order to satisfy specifications, I implemented lp_ticker_set_interrupt() function.
- lp_ticker.c lp_ticker_fire_interrupt()
In order to satisfy spec, I implemented lp_ticker_fire_interrupt() function.
Also I added GIC_EnableIRQ for allowing the interrupt at end of function.
- lp_ticker.c lp_ticker_get_info()
To satisfy the spec, I implemented lp_ticker_get_info() function. The value of freq includes rounding off.
i2c_api implementation for NRF52 does a disable() followed by uninit().
The uniinit() implementation in NRF drivers layer makes another call to
disable. This throws off the state of the I2C instance leading to an
assert. Since the disable is only invoked from the I2C API layer for
Nordic, remove this redundant call.

The ITM must be initialized before the SoftDevice, but due to the
lazy initialization in C++ on (at least) GCC the ITM init call
might happen too late.
This commit moves the initialization code into the NRF52 system
startup file.
1. Rename m2351_stddriver_sup.h/c to stddriver_secure.h/.c for naming consistency
2. Add hal_secure.h to include hal-exported secure functions
3. Change return/argument type in secure functions:
(1) Change int to int32_t
(2) Change PinName to int32_t
(3) Change time_t to int64_t
4. Update secure lib/bin accordingly
1. Power down RTC access from CPU domain in rtc_free. After rtc_free, RTC gets
inaccessible from CPU domain but keeps counting.
2. Fix RTC cannot cross reset cycle.
To initialize/uninitialize H/W module, we need to control secure SYS/CLK regions through secure functions.
For a new thread to call these secure functions, we need to allocate secure context for it.
To change TRNG security state, we need to:
1. Change CRPT/CRYPTO bit in NVIC/SCU in partition_M2351.h
2. Add/remove TRNG in device_has list in targets.json to match partition_M2351.h
NSC location has the following requirements:
1. By IDAU, 0~0x4000 is secure. NSC can only locate in 0x4000~0x10000000.
2. Greentea flash IAP uses last 4 sectors for its test. Avoid this range.
3. Greentea NVSTORE uses last 2 sectors or 4KB x 2 for its test. Avoid this range.
In Mbed OS, page size is program unit, which is different than FMC definition.
After fixing page size, we can pass NVSTORE test (mbed-os-features-nvstore-tests-nvstore-functionality).
1. Replace SYS_ResetModule/CLK_SetModuleClock/CLK_EnableModuleClock/CLK_DisableModuleClock with TrustZone-aware versions.
2. Configure all UART to secure
3. Support asynchronous transfer
4. Remove sleep management code, which has been replaced with Sleep Manager.
The rework includes the following:
1. Remove ticker overflow handling because upper layer (mbed_ticker_api.c) has done with it.
This makes us_ticker/lp_ticker implementation more succinct and avoids potential error.
2. Refine timer register access with low-power clock source
1. Revise NU_PORT_BASE to be TrustZone-aware
2. Add TrustZone-aware NU_GET_GPIO_PIN_DATA/NU_SET_GPIO_PIN_DATA to replace GPIO_PIN_DATA
3. Revise pin_function to be TrustZone-aware
All modules are configured to non-secure except:
1. TIMER0/1 hard-wired to secure and TIMER2/3 reserved for non-secure.
2. PDMA0 hard-wired to secure and PDMA1 reserved for non-secure.
3. RTC configured to secure and shared to non-secure through NSC.
4. CRYPTO configured to secure and shared to non-secure through NSC.
1. NUMAKER_PFM_M2351 defaults to non-secure
2. Add NUMAKER_PFM_M2351_S/NUMAKER_PFM_M2351_NS which are for secure/non-secure build respectively.
3. Change output format to Intel HEX
4. Fix device name to M2351KIAAEES from M2351K1AAEES
5. Add detect_code
As per SAU documents, SAU is always present if the security extension is
available. The functionality differs if the SAU contains SAU regions.
If SAU regions are available it is configured with the macro __SAUREGION_PRESENT
- Move back the 16/32bit timer initialization in HAL_InitTick() and not in us_ticker_init()
- Use ticker_read_us() and us_ticker_read() in HAL_GetTick() to fix potential overflow issue with the 16bit timer
==> These corrections allow timer, rtc, sleep, tick tests to PASS
- RTC_SSR for the subseconds
- RTC_TR for the time
- RTC_DR for the date
These registers were accessed through shadow registers which are synchronized with PCLK1 (APB1 clock).
They are now accessed directly in order to avoid waiting for the synchronization duration.
This change is to reduce delay of wake-up from power-down to pass Greentea test.
Because HIRC's accuracy is worse than HXT's, we must switch back to HXT for e.g. USBD application.
This can be done through setting NU_CLOCK_PLL to NU_HXT_PLL.
* Elevate RTC2 interrupt priority to same level as UARTE to prevent
race condition on shared variables.
* Remove unused TXDRDY event code.
* Fix typo in macro.
In serial_tx_active and serial_rx_active functions,
we check the internal state value with
HAL_UART_STATE_BUSY_TX = 0x21U,
HAL_UART_STATE_BUSY_RX = 0x22U,
It seems that value can also be :
HAL_UART_STATE_BUSY_TX_RX = 0x23U,
It has been noticed that there is a problem with us ticker on NRF_52840 board after 32 bit counter has been used for us ticker on NRF52 family boards.
Currently NRF52 symbol is defined only for MCU_NRF52832 (not for MCU_NRF52840) and based on this symbol 16 or 32 bit counter is selected (16 bit for NRF51 family and 32 for NRF52 family).
Since MCU_NRF52840 defines NRF52840_XXAA and provides 32 bit counters, 32 bit counter should be selected also when NRF52840_XXAA symbol is defined.
These wiced targets are not supported at mbed-os 2 release, so removing
"2" from release_versions.
LWIP feature flag removed, since it isn't needed anymore.
EMAC removed from device_has_add, since it isn't needed with these targets.
"network-default-interface-type": "WIFI" has been added.
1. Introduce S/W interrupt enable/disable to reduce calls to TIMER_EnableInt/TIMER_DisableInt.
2. Allow dummy interrupt because clear interrupt flag is not synchronized.
3. Enable LPTICKER_DELAY_TICKS to make lp_ticker_set_interrupt non-blocking.
Decreased stack size from 24kB to 1kB (stack is used on boot-up/interrupt
handler). Increased heap size from 65kB to 89kB.

New changes to Mbed error reporting in 5.9 exposed bug in SPI
driver where an instance was uninitialized twice which triggered
an ASSERT.
This fix keeps track of which instance has been initialized and
only calls uninit when it is safe.
There are cases where a call hal_deepsleep would overflow the idle task
stack, especially in developper or debug profile.
In order to avoid this case, we split ForceClockOutofDeepSleep
into two separate functions the two structure RCC_ClkInitStruct and
RCC_OscInitStruct are not allocated at the same time.
Set the second highest user level, leaving the highest for UART (we are having constant overflows) and two levels below for everything else.
This should increase the timer accuracy.
1. Problems were seen on the LPC54628 as the ADC clock source was too

RTC counter is 24-bit. Upper layer handles counter size and wraps ticks count when interrupt is to be fired before passing it to common_rtc_set_interrupt(), but for consistency and safety reasons we can wrap it again in the NRF driver.
The nrf section features has different implementations for each compilers supported by mbed-os. The header guard was ruling out compiler other than GCC by checking if __GNUC__ is defined. This check is not applicable on mbed os as the ARM compiler compile sources with gnu compatibility.
This patch makes sure that the right implementation is selected for the right compiler . The previous patch has been reverted as it is not reliable.
mbed RTC specifications now dictate that the RTC needs to retain and keep on counting through reset. On Silicon Labs parts, this means the RTC API can not be backed by the Silicon Labs RTC peripheral, since that doesn't provide retention functionality.
Therefore:
* On EFM32GG, EFM32WG, EFM32LG: mbed RTC API is now backed by BURTC.
* On EFM32PG, EFR32MG, EFM32PG12, EFR32MG12: mbed RTC API is now backed by RTCC.
* On EFM32ZG, EFM32HG: mbed RTC API is sadly no longer supported, since these chips don't have retained memory.
I implemented the RTC feature.
The mainly changing is here.
- rtc_init()
Previously, I have initialized the time information register in the function, so the time count was cleaned by every calling rtc_init().
Currently, rtc_init() doesn't stop RTC from counting, and rtc_init() is safe to call repeatedly.
Therefore in order to satisfy specifications,I removed the initialization process of the time information register in the function.
- rtc_free()
Previously, I have initialized the RTC related register same as rtc_init(), so the time count was cleaned by calling rtc_free().
Currently, rtc_free() doesn't stop RTC from counting.
Therefore in order to satisfy specifications,I removed the process and decided not to do anything in the function.
If powerdown the RTC, Supply of the clock to the RTC is stopped, cannot keeping the count.
Make rtc_isenabled() to return 1 if the RTC is initialized and the time has been set; 0 otherwise.
Disable clock gate on exit from this function if RTC was initialized.
Keep the RTC code if either DEVICE_RTC or DEVICE_LOWPOWERTIMER is
defined on the devices which use the RTC for both the rtc api and the
low power timer api. This allows DEVICE_LOWPOWERTIMER to be enabled while
DEVICE_RTC is turned off.
- Disable microsecond ticker interrupt on reinitialization
- Skip us_ticker_set_interrupt() if timestamp is already past
- Eliminate tmr2Config since tmrConfig is adequate for all timer config
1. Enable LPTICKER for K22, K24, K64, K66, K82, KL82F, KW24D

I decided to move these files to the targets/TARGET_NORDIC/TARGET_NRF5x/TARGET_NRF51 since us_ticker.h is for sure specific for NRF51_DK and common_rtc.c might be valid also for NRF52, but this needs to be checked while porting NRF52_DK board.
Provide the following modifications for lp ticker driver:
- According to NRF51_DK reference manual rtc interrupt cannot be controlled by rtc event. In the previous implementation interrupts were enabled permanently and specific interrupt was enabled/disabled by enabling/disabling the specific event. If event is enabled, then event signal is provided to Programmable Peripheral Interconnect (PPI). If interrupt is enabled, then interrupt signal is provided to Nested Vector Interrupt Controller (NVIC). Disable all events permanently. Enable lp ticker overflow interrupt permanently(needed for RTC), disable lp ticker capture/compare interrupt on init (lp_ticker_init) , enable lp ticker interrupt when lp ticker interrupt is set (lp_ticker_set_interrupt), disable lp ticker interrupt on disable request(lp_ticker_disable_interrupt).
- Provide lp ticker data for higher level (freq: 32kHz / len: 24 bits),
- Add the following features to init routine: disable lp ticker interrupt.
- Make ticker driver to operate on ticks instead of us.
- Simplify lp ticker read and set interrupt routines (upper layers handle conversion to us and interrupt scheduling).
According to new ticker standards the following requirements for us ticker are not met on RRF5 boards:
- has a frequency between 250KHz and 8MHz (currently is driven by 32kHz clock)
- ticker increments by 1 each tick (currently is scaled to 1 MHz by incrementing counter by ~31)
Since BLE softdevice uses TIMER0 the proposition is to use high speed TIMER1 for us ticker configured as follows:
- TIMER counter width: 16 bits (max)
- TIMER frequency: 1MHz
This solution also uses Timer's capture/compare register 0 to specify interrupt time and Timer's capture/compare register 1 to read current timer value.
I implemented USTICKER feature.
The mainly changing is here.
- I added a macro to mbed_drv_cfg.h for commonalizing code for GR-PEACH and GR-LYCHEE with different clock frequencies, and referenced it's macro at us_ticker.c.
- ticker_init()
Currently, ticker_init() keep counting, disables the ticker interrupt, and is safe to call repeatedly.
Therefore, in order to satisfy specifications, I removed GIC_EnableIRQ at end of function and added GIC_DisableIRQ at begin of function.
When an interrupt is required, it will be set with ticker_set_interrupt().
If executing the following, the counter has been initialized. So it will not call after executing the first time.
OSTM1TT = 0x01; /* Stop the counter and clears the OSTM1TE bit. */
OSTM1TS = 0x1; /* Start the counter and sets the OSTM0TE bit. */
- ticker_free()
this function stops the counting and powerdown the us_ticker.
To satisfy the mbed specificationm, I implemented free() function.
- ticker_read()
Currently, Mbed spec's frequeny is between 250KHz and 8MHz, but the frequency that is used at my ticker is 33MHz.
Therefore, in order to satisfy specifications, I changed the process to return the timer counter value divided by 32(33MHz / 32).
Since the calcurate function by using 64 bit is no longer necessay, I removed it.
- ticker_set_interrupt()
Same as the above read(),
In order to satisfy specifications, I changed the process to set the value multiplied by 32.
- ticker_fire_interrupt()
In order to satisfy specifications, I implemented fire_interrupt() function.
Also I added GIC_EnableIRQ for allowing the interrupt at end of function.
- ticker_get_info()
To satisfy the mbed specificationm, I implemented ticker_get_info() function. The value of freq includes rounding off.
The new HAL allows to share the timer bit width and frequency,
the actual handling of mapping 16 bits counter up to 32 bits or
64 bits is now managed by mbed common layer.
This makes this ticker layer very similar to 32bits one and much
easier than before.
Re-implemented both us_ticker and lp_ticker to match the new API and specifications.
Details:
* On EFM32GG, EFM32WG, EFM32LG, EFM32HG, EFM32ZG: Use the RTC peripheral to back lp_ticker, and a TIMER to back us_ticker.
* On EFM32PG, EFR32MG, EFM32PG12, EFR32MG12: Use the RTCC peripheral to back lp_ticker (dual-purpose, also used to back RTC), and a TIMER to back us_ticker.
mbed RTC specifications now dictate that the RTC needs to retain and keep on counting through reset. On Silicon Labs parts, this means the RTC API can not be backed by the Silicon Labs RTC peripheral, since that doesn't provide retention functionality.
Therefore:
* On EFM32GG, EFM32WG, EFM32LG: mbed RTC API is now backed by BURTC.
* On EFM32PG, EFR32MG, EFM32PG12, EFR32MG12: mbed RTC API is now backed by RTCC.
* On EFM32ZG, EFM32HG: mbed RTC API is sadly no longer supported, since these chips don't have retained memory.

Low power ticker time counter is created based on RTC which is driven by 32KHz clock. Additional low power timer is used to generate interrupts.
We need to adapt driver to operate on ticks instead of us.
Perform the following updates:
- provide lp ticker configuration: 32KHz/32 bit counter.
- lp_ticker_init() routine disables lp ticker interrupts .
- adapt the driver functions to operate on ticks instead us.
- adapt comments.
- add us_ticker_free() routine.
I implemented the SLEEP feature for Rnesas mbed boards.
The mainly changing is here.
- hal_sleep()
To satisfy the mbed specificationm, I implemented this function newly by using "sleep" that is one of low power mode that is incorporated in our hardware(RZ_A1).
In the "sleep", peripheral and memory state are maintained, and the peripherals continue to work and can generate interrupts.
- hal_deepsleep()
To satisfy the mbed specificationm, I implemented this function newly by combined using "sleep" and "module standby" that is the low power mode that is incorporated in our hardware(RZ_A1).
The "module standby" is peripheral module's powerdown.
Also in case of our "module standby", it need to read register as dummy when access to each register.
These boards will be re-enabled when sleep driver for them is ready.
Note:
This operation is done by removing "SLEEP" feature from target's "device_has" list (in targets.json config file).
For NRF52_DK removing of "SLEEP" feature causes some timing issues which have influence on tests. In order to successfully disable this board we need to disable also related features like "USTICKER", "LOWPOERTIMER" and slightly modify ticker tests, so they will not be executed if usticker support is not available (by default all targets support us ticker).
Sleep - within 10us
Deepsleep - within 10ms
Note about mbed boards with interface, moved to lpc176x, as they are target related,
should be documented in the target documentation.
The tests will come as separate PR, to conform to this updates to sleep API.
Patch to LPC546XX SDK code - write the low Ethernet MAC address
register last, as that synchronises the update.
Without this change, the ENET_SetMacAddr call only seems to work prior
to MAC initialisation, causing problems for the new mbed OS EMAC system,
which expects it to be changable later.
Updated emac greentea tests #6851.
Implementation of unified EMAC driver for Renesas mbed boards
Based on the driver so far, Renesas implemented the emac driver for GR-PEACH and VK-RZ/A1H.
The mainly changes is below.
- Add the connection part with LWIP according to the unified emac specification.
- Add three new multicast functions(add, remove, set_all).
The Greentea test netsocket and emac test passed.
Just checking "does the chip have an EMAC" doesn't work - there are
targets using those chips which do not have an Ethernet connector and
don't provide the necessary surrounding infrastructure (eg DISCO_F429ZI,
not providing the board emac config call, and HEXIWEAR not providing PHY
info).
Make the targets that actually do want EMAC define their own local
Freescale_EMAC and STM_EMAC labels, and move the drivers into
the corresponding TARGET_ directories, removing the #ifdefs.
* Since mbed does not overwrite itself, make the flashing routines run out of flash by default
* Report a writeable size of 4 bytes (previously erroneously reported a full eraseable page as the minimum write size)
* IRQ handling got updated previously to a non-functional state when both callbacks were registered (it'd fire a fall callback for both rise and fall events). With this update, that faulty behaviour is corrected. Due to delays between the detection of the edge and the handling of the interrupt (and the fact that information about which edge you received on the pin is not stored anywhere), there is no way to be absolutely sure which edge got triggered on the pin. Therefore, we make a best-guess effort by looking at the pin state at the time of IRQ handling, and fire a callback as if that was the end state of the event. This will usually work out fine, except in cases were the signal is toggling faster than the IRQ handler's response time. In that case, a user won't get both callbacks (as expected for a pulse), but only the last event.
* Stripped some dead code.
Initial work by Bartek Szatkowski in https://github.com/ARMmbed/mbed-os/pull/4079,
reworked following review of https://github.com/ARMmbed/mbed-os/pull/5202 to
transform the entire system into C++, retaining the basic functionality.
Bartek's summary:
* Porting ethernet to EMAC
* Updating EMAC to enable multiple interfaces
* Untangling networking classes, making the abstractions a bit clearer to follow, etc
* General refactoring
* Removal of DEVICE_EMAC flag and introducing DEVICE_ETH and DEVICE_WIFI
Revisions since initial branch:
* Remove lwip depencies
* Correct doxygen warnings
* Remove emac_api.h, replace with C++ EMAC abstract class.
* Create OnboardNetworkInterface, and LWIP implementation.
* Mappings since #4079
lwip-interface/nsapi_stack_lwip.c -> LWIPStack.cpp
lwip-interface/ipstack_lwip.c -> LWIPInterface.cpp
netsocket/mbed_ipstack.h -> OnboardNetworkStack.h
hal/emac_api.h -> EMAC.h
* Reinstate use of EthInterface abstraction
* Correct and clarify HW address EMAC ops
* Restore MBED_MAC_ADDR implementation
* Integrate PPP support with LWIP::Interface.
* Convert K64F lwIP driver to K64F_EMAC.
To do:
* Convert emac_stack_mem.h to follow this pattern.
* Figure out DEVICE_ETH/EMAC
* Update all drivers to use EMAC
New directory structure:
* TARGET_SOFTDEVICE_COMMON
* TARGET_SOFTDEVICE_S112
* TARGET_SOFTDEVICE_S132_FULL (MBR + SoftDevice, default)
* TARGET_SOFTDEVICE_S132_OTA (SoftDevice only, for firmware updates)
* TARGET_SOFTDEVICE_S132_MBR (MBR only, for bootloader builds)
* TARGET_SOFTDEVICE_S140_FULL (MBR + SoftDevice, default)
* TARGET_SOFTDEVICE_S140_OTA (SoftDevice only, for firmware updates)
* TARGET_SOFTDEVICE_S140_MBR (MBR only, for bootloader builds)
* TARGET_SOFTDEVICE_NONE
The X_OTA and X_MBR binaries are obtained from the original x_FULL SoftDevice
by splitting it in an MBR part and a SoftDevice part. The MBR is needed for
the bootloader and the SoftDevice for firmware updates.
Build application without SoftDevice:
"target_overrides": {
"*": {
"target.extra_labels_remove": ["SOFTDEVICE_COMMON", "SOFTDEVICE_X_FULL"],
"target.extra_labels_add": ["SOFTDEVICE_NONE"]
}
}
Build application for firmware update using SoftDevice X:
"target_overrides": {
"*": {
"target.extra_labels_remove": ["SOFTDEVICE_X_FULL"],
"target.extra_labels_add": ["SOFTDEVICE_X_OTA"]
}
}
Build bootloader without SoftDevice X:
"target_overrides": {
"*": {
"target.extra_labels_remove": ["SOFTDEVICE_COMMON", "SOFTDEVICE_X_FULL"],
"target.extra_labels_add": ["SOFTDEVICE_X_MBR"]
}
}
After rebase, the build target NRF52840_DK is using TARGET_NRF5x,
instead of TARGET_NRF5. Moved Cryptocell TRNG related code from
`targets/TARGET_NORDIC/TARGET_NRF5/` to `targets/TARGET_NORDIC/TARGET_NRF5x/`
In current implementation `rtc_read` function returns number of elapsed us and `rtc_write` function sets RTC time to specified value in us.
Mbed HAL API expects that these functions operate on seconds.
Since lp ticker is also based on RTC provide mechanism to trace elapsed seconds without modifying RTC registers.
The unified NRF51 target and feature BLE directories have been
reorganized to follow the naming and directory structure of the
NRF52 implementation.
This reorganization does not include TARGET_MCU_NRF51822 and
derived targets.
The MBR VTOR state depends on how the application is booted.
This makes it difficult to initialize the MBR correctly since a
bug prevents the MBR from being initialized more than once.
This commit resets the MBR and SoftDevice to a known state before
initializing the MBR and setting the VTOR through the SoftDevice.
Delayed initialization can cause problems when both UARTE instances
are in use. This change causes each UART object to initialize the
underlying UARTE instance immediately.
Certain instances of the TPM are missing some registers, updated
TPM driver handles this variation. This issue was discovered when
running the PWMOUT tests using the ci-test-shield

IAR 7.8 does not support dynamic heap, and some test/addition of new
feature fail on this device because of less static RAM memory.
Reducing the heap memory size for the same reason.
The vector table relocation sequence depends on:
1. Whether the SoftDevice is present.
2. The Application is a bootloader or not.
If the SoftDevice is present and the application is a bootloader
the MBR must be initialized to trap SoftDevice service calls
before setting the new vector table address.
The SCB->VTOR must be set to point at the MBR as well.
If the SoftDevice is not present the SCB->VTOR can point at the
new vector table directly.
We cannot rely on the default value as a pin could

SPI pins are not initialized correctly according to the current
SPI mode.
This commit changes how the SPI instance is configured and ensures
that:
1. SPI pins are initialized on each object initialization.
2. SPI pins are reinitialized on each mode or object change.
3. SPI instance is only initialized when a change has occured.
