Helps prevent the filesystem from getting formatted by mistake, among other
things. For example, on a Pico board, entering Ctrl+D and Ctrl+C fast many
times will eventually wipe the filesystem (without warning or notice).
Further rationale: Ctrl+C is used a lot by automation scripts (eg mpremote)
and UI's (eg Mu, Thonny) to get the board into a known state. If the board
is not responding for a short time then it's not possible to know if it's
just a slow start up (eg in _boot.py), or an infinite loop in the main
application. The former should not be interrupted, but the latter should.
The only way to distinguish these two cases would be to wait "long enough",
and if there's nothing on the serial after "long enough" then assume it's
running the application and Ctrl+C should break out of it. But defining
"long enough" is impossible for all the different boards and their possible
behaviour. The solution in this commit is to make it so that frozen
start-up code cannot be interrupted by Ctrl+C. That code then effectively
acts like normal C start-up code, which also cannot be interrupted.
Note: on the stm32 port this was never seen as an issue because all
start-up code is in C. But now other ports start to put more things in
_boot.py and so this problem crops up.

This provides a standard interface to setting the global networking config
for all interfaces and interface types.
For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).
For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.
Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).

Before, both uwTick and mp_hal_ticks_ms() were used as clock source. That
assumes, that these two are synchronous and start with the same value,
which may be not the case for all ports. If the lag between uwTick and
mp_hal_ticks_ms() is larger than the timer interval, the timer would either
rush up until the times are synchronous, or not start until uwTick wraps
over.
As suggested by @dpgeorge, MICROPY_SOFT_TIMER_TICKS_MS is now used in
softtimer.c, which has to be defined in a port's mpconfigport.h with
the variable that holds the SysTick counter.
Note that it's not possible to switch everything in softtimer.c to use
mp_hal_ticks_ms() because the logic in SysTick_Handler that schedules
soft_timer_handler() uses (eg on mimxrt) the uwTick variable directly
(named systick_ms there), and mp_hal_ticks_ms() uses a different source
timer. Thus it is made fully configurable.
The default now includes all sub-components (security, l2cap, etc)
and using the kwarg options is no longer supported.

This drops the `.cpu` directive from the ARM gchelper_*.s files. Having

For STM32L4, hardware I2C can be implemented by using TIMINGR.
This commit enables:
- Use of hardware I2C in machine.I2C.
- Specifying a frequency greater than or equal to 400KHz with pyb.I2C.
For STM32L4 series, the internal sensors are connected to:
- ADC1_IN0: Internal voltage reference
- ADC1_IN17: Temperature sensor
- ADC1_IN18: VBAT battery voltage monitoring
but ADC_CHANNEL_VREFINT, ADC_CHANNEL_VBAT, ADC_CHANNEL_TEMPSENSOR are not
defined as 0, 17, 18.
This commit converts channel 0, 17, 18 to ADC_CHANNEL_x in
adc_get_internal_channel().
Prior to this commit, the actual I2C frequency can be faster than specified
one and it may exceed the I2C's specification for Fast Mode. The frequency
of SCL should be less than or equal to 400KHz in Fast Mode.
This commit fixes this issue for F4 MCUs by rounding up the division in the
frequency calculation.
Excuting the code:
i2c = I2C(1, I2C.CONTROLLER, dma=True)
tmp = i2c.recv(1, i2c_addr)
recv_data = bytearray(56)
i2c.recv(recv_data, i2c_addr)
The second i2c.recv() fails with OSError: [Errno 110] ETIMEDOUT. When
receiving greater than or equal to 2 bytes at first i2c.recv(), the second
i2c.recv() succeeds. This issue does not occur without DMA.
Details of change: when executing I2C with DMA:
- Bit 11 of I2Cx_CR2 (DMA Request Enable) should be 1 to indicate that DMA
transfer is enabled. This bit is set after I2C event interrupt is
enabled in HAL_I2C_Master_Transmit_DMA()/HAL_I2C_Master_Receive_DMA(), so
DMA Request Enable bit might be 0 in IRQHandler.
- In case of data receive:
- When only 1 byte receiption, clear I2Cx_CR1's bit 10 (ACK).
- When only 2 byte receiption, clear I2Cx_CR1's bit 10 (ACK) and set
bit 11 (POS).
- When greater than or equal to 2 byte receiption, bit 12 of I2Cx_CR2
(DMA Last Transfer) should set to generate NACK when DMA transfer
completed.
Otherwise, the I2C bus may be busy after received data from peripheral.
A board can now name the CDC ports, eg:
#define MICROPY_HW_USB_CDC_NUM (3)
#define MICROPY_HW_USB_INTERFACE_CDC0_STRING "REPL"

The rp2 port already has ECDH enabled, so this just adds ECDSA there. The

- stm32 (PYBD_SF6): +20480 bytes flash, +32 bytes data, +48 bytes BSS

- unix (standard x86-64): +39344 executable, +1744 bytes data, +96 BSS
This is obviously a large increase in code size. But there doesn't seem to
be any other option because without elliptic curve cryptography devices are
partially cut off from the internet. For use cases that require small

Instead of being an explicit field, it's now a slot like all the other

The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.
This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
to a mp_getiter_iternext_custom_t instance, which then defines both
getiter and iternext.
And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.
Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

Since L4 HAL version 1.17.0, HAL_TIM_IC_Start_IT() checks whether specified
channel of timer is busy or not, which is the case if this function is
called more than once without first calling HAL_TIM_IC_Stop_IT(). The fix
in this commit is to call the stop function before calling start. The PWM
and OC modes have the same issue with the same fix.
Fixes issue #8732.
Prior to this commit, excuting this code:
i2c = I2C(1, I2C.CONTROLLER, dma=True)
i2c.send(data, addr=i2c_addr)
the call to i2c.send() does not return and the board needs a reset. This
code works when dma=False.
According to the specification, I2Cx_EV_IRQHandler should:
- Write DR to address when Start condition generated.
- Clear ADDR by reading SR2 after reading SR2 when address sent.
These processes are included in HAL_I2C_EV_IRQHandler(), however the
firmware size increses about 2KB if HAL_I2C_EV_IRQHandler is called. This
commit adds above processes to i2c_ev_irq_handler, and increases firmware
by less than 100 bytes.
Fixes issue #2643.
pyb.ADC(channel) checks whether specified channel is valid or have ADC
capability but pyb.ADCAll().read_channel() does not.
This change adds checking whether specified channel is valid and throw

If mboot is built with support for packing (signing/encryption) it needs up
to 32KiB. So for simplicity increase the mboot region to 32KiB
unconditionally for WB55 boards (custom WB55 board configurations can still
provide their own linker scripts to override this).
Since commit e65d1e69e8 there is no longer an
io.FileIO class, so this option is no longer needed.
This option also controlled whether or not files supported being opened in
binary mode (eg 'rb'), and could, if disabled, lead to confusion as to why
opening a file in binary mode silently did the wrong thing (it would just
open in text mode if MICROPY_PY_IO_FILEIO was disabled).
The various VFS implementations (POSIX, FAT, LFS) were the only places
where enabling this option made a difference, and in almost all cases where
one of these filesystems were enabled, MICROPY_PY_IO_FILEIO was also
enabled. So it makes sense to just unconditionally enable this feature
(ability to open a file in binary mode) in all cases, and so just remove
this config option altogether. That makes configuration simpler and means
binary file support always exists (and opening a file in binary mode is
arguably more fundamental than opening in text mode, so if anything should
be configurable then it should be the ability to open in text mode).

In-the-field use of these FUS/WS firmware update scripts has exposed some
weak points, causing corrupted FUS/WS firmware to be flashed to the unit.
The problems are mostly caused with the ST GUI application, but sometimes
from un-recognised failures during bin file transfer to the WB55 prior to
running the rfcore_firmware.py script. Other failures were caused by
incorrect load addresses being used, again both from user error copying the
address from the HTML release notes to the GUI tool, but also from
similarly not updating the address correctly in rfcore_firmware.py
To guard against these errors and make it easier to prepare different
versions, this commit adds a few features to the rfcore firmware update
tools:
- When creating the bin file, automatically parse the release note in the
folder to get the correct address.
- Add a footer to the bin file containing the name, version, CRC, address
etc.
- Before flashing rfcore, check if the same version is already installed.
- Verify the CRC and obfuscation key before flashing bin.
- Log the name and version of file being flashed.

The _bl_state address is the same as _estack, but _estack is referred to as
a uint32_t elsewhere in the code. LTO doesn't like it when the same symbol
has two different types.

This separates extmod source files from `py.mk`. Previously, `py.mk`
assumed that every consumer of the py/ directory also wanted to include
extmod/. However, this is not the case. For example, building mpy-cross
uses py/ but doesn't need extmod/.
This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and
explicitly includes `extmod.mk` in ports that use it.

Both led_init and led_state are configurable via MBOOT_BOARD_LED_INIT and
MBOOT_BOARD_LED_STATE respectively, so don't need to be MP_WEAK.
Furthermore, led_state and led0_state are private to ui.c so can be made
static.

System config block contains hardware unrelated to USB. So calling
`__SYSCFG_CLK_DISABLE()` during `HAL_PCD_MspDeInit()` has an adverse effect
on other system functionality.
Removing call to `__SYSCFG_CLK_DISABLE()` to rectify this issue.
This call was there since the beginning of the USB CDC code, added in
b30c02afa0.
According to ST Errata ES0206 Rev 18, Section 2.2.1, on STM32F427x,
STM32F437x, STM32F429x and STM32F439x.
If the system tick interrupt is enabled during stop mode while certain
bits are set in the DBGMCU_CR, then the system will immediately wake
from stop mode.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.
According to ST Errate ES0394 Rev 11, Section 2.2.17, on STM32WB55Cx and
STM32WB35Cx.
If the system tick interrupt is enabled during stop 0, stop 1 or stop 2
while certain bits are set in DBGMCU_CR, then system will immediately
wake from stop mode but the system remains in low power state. The CPU
therefore fetches incorrect data from inactive Flash, which can cause a
hard fault.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.
This was added by mistake in 8f68e26f79 when
adding support for G4 MCUs, which does not using this get_bank() function.
FLASH_OPTR_DBANK is only defined on G4 and L4 MCUs, so on H7 this
FLASH_BANK_2 code was being wrongly excluded.

It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

The following changes are made:
- Use software SPI for external SPI flash access when building mboot.
- Enable the mboot filesystem-loading feature, with FAT FS support.
- Increase the frequency of the CPU when in mboot to 96MHz, to increase the
speed of SPI flash accesses and programming.

For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.
This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

This replaces occurences of

foo->base.type = &foo_type;
with

Excludes any places where base is a sub-field or when new0/memset is used.

To avoid any I/O glitches in mp_hal_pin_config, make sure a valid alternate
function is set in AFR first before switching the pin mode. When switching
from AF to INPUT or OUTPUT, the AF in AFR will remain valid up until the
pin mode is switched.
- Add board-level configuration option to set the SMPS supply mode.
- Wait for valid voltage levels after configuring the SMPS mode.
- Wait for external supply ready flag if SMPS supplies external circuitry.
All user interface (LED, button) code has been moved to ui.c, and the
interface to this code with the rest of the system now goes through calls
to mboot_state_change(). This state-change function can be overridden by a
board to fully customise the user interface behaviour.

The CAN.initfilterbanks() class method is removed, and its functionality is
replaced with the "num_filter_banks" keyword argument to the CAN
constructor and CAN.init(). This configures the filter bank split.
This new approach provides more flexibility configuring the resources used
by a given CAN instance, allowing other MCUs like H7 to fit the API. It
also brings CAN closer to how other machine peripherals are configured,
where everything is done in the constructor/init method.
This is a breaking change to the CAN API.
CAN.recv() now returns a 5-tuple, with the new element in the second
position being a boolean, True if the ID is extended.
This is a breaking change of the API for CAN.recv().
A CAN bus can have mixed classic/FD nodes. Prior to this patch the CAN API
could be configured for either standard or extended ID, but not both/mixed
operation.
This patch allows extended IDs to be filtered and enabled on a per-message
basis, in send(), setfilter() and clearfilter().
This is a breaking change to the API: init() no longer accepts the extframe
keyword argument.
- Enable CAN FD frame support and BRS.
- Optimize the message RAM usage per FDCAN instance.
- Document the usage and different sections of the Message RAM.
In particular, it is called by the constructor if the instance already
exists. So if the previous instance was deinit'd then it will be deinit'd
a second time.
