1. Problems were seen on the LPC54628 as the ADC clock source was too
high
2. Moved the pin configuration to set Analog mode to the end of the
function

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.
We cannot rely on the default value as a pin could
be use for Analog purposes in which this bit is cleared

The ci-shield tests that manually generate the START, STOP
by calling the HAL functions were failing. The byte operation
HAL functions cannot use the MCUXpresso SDK driver API's.

Since revision 5499db1 (mbed-os-5.6.0) a hardfault occurs after a power-cycle.
It doesn't occur after a reset when the application has been downloaded using
drag-and-drop or via debugger. This is probably the reason why this problem
isn't detected when testing new mbed releases.
The hardfault occured in hal_sleep(). Adding a __NOP after __WFI solves the
problem although I don't fully understand why.
- Revision ca661f9 is the last revision where the problem doesn't occur.
- The problem doesn't occur when compiling with GCC instead of ARM compiler
- This issue describes a similar, but not identical problem and led me to test adding a __NOP: https://github.com/ARMmbed/mbed-os/issues/5065
* Add source address word alignment check
* malloc and memcpy are called only if data is unaligned
* malloc size is now copySize (program page size), rather than whole buffer to be written
This patch fix flash write issue when program size is more than page size (= 1024 bytes). See detail - https://github.com/ARMmbed/mbed-os/issues/6165
Source data always use aligned data in heap memory.
Target of LPC1769 links to mbed LPC1768.
The PinNames.h has conditional compile for the pin names.
LWIP lpc17xx emac driver modified to allow LPC1769 target

32.3.2.6 Interrupts during IAP
The on-chip flash memory is not accessible during erase/write operations. When the user
application code starts executing the interrupt vectors from the user flash area are active.
The user should either disable interrupts, or ensure that user interrupt vectors are active in
RAM and that the interrupt handlers reside in RAM, before making a flash erase/write IAP
call. The IAP code does not use or disable interrupts.
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.
fire_interrupt function should be used for events in the past. As we have now
64bit timestamp, we can figure out what is in the past, and ask a target to invoke
an interrupt immediately. The previous attemps in the target HAL tickers were not ideal, as it can wrap around easily (16 or 32 bit counters). This new
functionality should solve this problem.
set_interrupt for tickers in HAL code should not handle anything but the next match interrupt. If it was in the past is handled by the upper layer.
It is possible that we are setting next event to the close future, so once it is set it is already in the past. Therefore we add a check after set interrupt to verify it is in future.
If it is not, we fire interrupt immediately. This results in
two events - first one immediate, correct one. The second one might be scheduled in far future (almost entire ticker range),
that should be discarded.
The specification for the fire_interrupts are:
- should set pending bit for the ticker interrupt (as soon as possible),
the event we are scheduling is already in the past, and we do not want to skip
any events
- no arguments are provided, neither return value, not needed
- ticker should be initialized prior calling this function (no need to check if it is already initialized)
All our targets provide this new functionality, removing old misleading if (timestamp is in the past) checks.
Restore cmsis_nvic (cmsis_nvic.c and cmsis_nvic.h) files for the
implementations which use a mechanism other than the VTOR to set
interrupts. These are vendor specific and were done for M0 devices
which do not have a VTOR.
Note - There were two cmsis_nvic files which did not use the VTOR that
which not restored in this patch. This is because these targets were
not M0 devices and could use the new unified implementation instead.
These files are:
targets\TARGET_ARM_SSG\TARGET_MPS2\TARGET_MPS2_M0P\device\cmsis_nvic.c
targets\TARGET_ONSEMI\TARGET_NCS36510\device\cmsis_nvic.c
Note - cmsis_nvic.c and cmsis_nvic.h were initial removed in
(and restored from) the commit:
b97ffe8fdc -
"CMSIS5: Replace target defined NVIC_Set/GetVector with CMSIS implementation"
The use of mktime was causing a fault when called in interrupt handler because on GCC it lock the mutex protecting the environment, To overcome this issue, this patch add dedicated routine to convert a time_t into a tm and vice versa.
In the process mktime has been optimized and is now an order of magnitude faster than the routines present in the C library.
For keep supporting external APIs with the same name (supposedly there are a larger
number of users of those APIs), BufferedSerial and ATParser are being renamed.
BufferedSerial becomes UARTSerial, will complement a future USBSerial etc.
ATParser becomes ATCmdParser.
* UARTSerial moves to /drivers
* APN_db.h is moved from platform to cellular/util/.
* Original CellularInterface is restored for backward compatability (again, supposedly there
are users of that).
* A new file, CellularBase is added which will now servce as the base class for all
upcoming drivers.
* Special restructuring for the driver has been undertaken. This makes a clear cut distinction
between an on-board or an off-board implementation.
- PPPCellularInterface is a generic network interface that works with a generic FileHandle
and PPP. A derived class is needed to pass that FileHandle.
- PPPCellularInterface provides some base functionality like network registration, AT setup,
PPP connection etc. Lower level job is delegated to the derived classes and various modem
specific APIs are provided which are supposed to be overridden.
- UARTCellularInterface is derived from PPPCellularInterface. It constructs a FileHandle and
passes it back to PPPCellularInterface as well as provides modem hangupf functionality.
In future we could proive a USBInterface that would derive from PPPCellularInterface and could
pass the FileHandle back.
- OnboardCellularInterface is derived from UARTCellularInterfae and provides hooks to
the target provided implementation of onbard_modem_api.h. An off-board modem, i.e, a modem on
a shield has to override the modem_init(), modem_power_up() etc as it cannot use
onboard_modem_api.h.
