Sébastien NEDJAR b04240cb77 stm32/Makefile: Make the generation of `firmware.bin` explicit.
The file `$(BUILD)/firmware.bin` was used by the target `deploy-stlink` and
`deploy-openocd` but it was generated indirectly by the target
`firmware.dfu`.

As this file could be used to program boards directly by a Mass Storage
copy, it's better to make it explicitly generated.

Additionally, some target are refactored to remove redundancy and be more
explicit on dependencies.

stijn 25c4563f26 examples: Add example code for user C modules, both C and C++.
Add working example code to provide a starting point for users with files
that they can just copy, and include the modules in the coverage test to
verify the complete user C module build functionality.  The cexample module
uses the code originally found in cmodules.rst, which has been updated to
reflect this and partially rewritten with more complete information.

stijn fad4079778 esp32,unix: Support building C++ code.
Support building .cpp files and linking them into the micropython
executable in a way similar to how it is done for .c files.  The main
incentive here is to enable user C modules to use C++ files (which are put
in SRC_MOD_CXX by py.mk) since the core itself does not utilize C++.

However, to verify build functionality a unix overage test is added.  The
esp32 port already has CXXFLAGS so just add the user modules' flags to it.
For the unix port use a copy of the CFLAGS but strip the ones which are not
usable for C++.

Damien George 0118c07916 stm32/machine_adc: Fix ADC auto-calibration to run when ADC not enabled.
Prior to this commit, the ADC calibration code was never executing because
ADVREGEN bit was set making the CR register always non-zero.

This commit changes the logic so that ADC calibration is always run when
the ADC is disabled and an ADC channel is initialised.  It also uses the LL
API functions to do the calibration, to make sure it is done correctly on
each MCU variant.

Damien George 581d43b774 stm32/usbd_cdc_interface: Check and handle CDC TX wrap-overflow.
If the device is not connected over USB CDC to a host then all output to
the CDC (eg initial boot messages) is written to the CDC TX buffer with
wrapping, so that the most recent data is retained when the USB CDC is
eventually connected (eg so the REPL banner is displayed upon connection).

This commit fixes a bug in this behaviour, which was likely introduced in
e4fcd216e0, where the initial data in the CDC
TX buffer is repeated multiple times on first connection of the device to
the host.

Damien George 39d50d129c ports: Add SoftI2C and SoftSPI to machine module where appropriate.
Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances.  Such
construction is now split to explicit soft and non-soft types.

This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.

This is a breaking change for use of software-based I2C and SPI.  Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:

    machine.I2C(-1, ...)            ->  machine.SoftI2C(...)
    machine.I2C(scl=scl, sda=sda)   ->  machine.SoftI2C(scl=scl, sda=sda)

    machine.SPI(-1, ...)            ->  machine.SoftSPI(...)
    machine.SPI(sck=sck, mosi=mosi, miso=miso)
                        ->  machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)

Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

Damien George 8f20cdc353 all: Rename absolute time-based functions to include "epoch".
For time-based functions that work with absolute time there is the need for
an Epoch, to set the zero-point at which the absolute time starts counting.
Such functions include time.time() and filesystem stat return values.  And
different ports may use a different Epoch.

To make it clearer what functions use the Epoch (whatever it may be), and
make the ports more consistent with their use of the Epoch, this commit
renames all Epoch related functions to include the word "epoch" in their
name (and remove references to "2000").

Along with this rename, the following things have changed:

- mp_hal_time_ns() is now specified to return the number of nanoseconds
  since the Epoch, rather than since 1970 (but since this is an internal
  function it doesn't change anything for the user).

- littlefs timestamps on the esp8266 have been fixed (they were previously
  off by 30 years in nanoseconds).

Otherwise, there is no functional change made by this commit.

Damien George b28758054b esp8266: Remove release-specific manifest, disable osdebug by default.
This commit removes release-specific builds for the esp8266 and makes the
normal build of the GENERIC board more like the release build.  This makes
esp8266 like all the other ports, for which there is no difference between
a daily build and a release build, making things less confusing.

Release builds were previously defined by UART_OS=-1 (disable OS messages)
and using manifest_release.py to include more frozen modules.

The changes in this commit are:
- Remove manifest_release.py.
- Add existing modules from manifest_release.py (except example code)
  to the GENERIC board's manifest.py file.
- Change UART_OS default to -1 to disable OS messages by default.

Jim Mussared 52d6eeb409 esp32/boards/sdkconfig.base: Set default IDF log level to ERROR.
This commit changes the default logging level on all esp32 boards to ERROR.
The esp32 port is now stable enough that it makes sense to remove the info
logs to make the output cleaner, and to match other ports.  More verbose
logging can always be reenabled via esp.osdebug().

This also fixes issue #6354, error messages from NimBLE: the problem is
that ble.active(True) will cause the IDF's NimBLE port to reset the
"NimBLE" tag back to the default level (which was INFO prior to this
commit).  Even if the user had previously called esp.osdebug(None), because
the IDF is setting the "NimBLE" tag back to the default (INFO), the
messages will continue to be shown.

The one quirk is that if the user does want to see the additional logging,
then they must call esp.osdebug(0, 3) after ble.active(True) to undo the
IDF setting the level back to the default (now ERROR).  This means that
it's impossible (via Python/esp.osdebug) to see stack-startup logging,
you'd have to recompile with the default level changed back to INFO.

Jim Mussared 126f972c34 extmod/nimble: Add timeout for HCI sync on startup.
This allows `ble.active(1)` to fail correctly if the HCI controller is

It also avoids an infine loop in the NimBLE event handler where NimBLE
doesn't correctly detect that the HCI controller is unavailable and keeps
trying to reset.

Furthermore, it fixes an issue where GATT service registrations were left
allocated, which led to a bad realloc if the stack was activated multiple
times.

Jim Mussared 311b8519af esp32: Pin MicroPython and NimBLE tasks to core 0.
MicroPython and NimBLE must be on the same core, for synchronisation of the

versions (3.3 and 4.0) there are issues (see e.g. #5489) with running
NimBLE on core 1.

This change - pinning both tasks to core 0 - makes it possible to reliably
run the BLE multitests on esp32 boards.

Prior to this commit, if you configure a pin as an output type (I2C in this

the type incorrectly.  Example:

    >>> import machine
    >>> b6 = machine.Pin('B6')
    >>> b6
    Pin(Pin.cpu.B6, mode=Pin.IN)
    >>> machine.I2C(1)
    I2C(1, scl=B6, sda=B7, freq=420000)
    >>> b6
    Pin(Pin.cpu.B6, mode=Pin.ALT_OPEN_DRAIN, pull=Pin.PULL_UP, af=Pin.AF4_I2C1)
    >>> b6.init(machine.Pin.IN)
    >>> b6
    Pin(Pin.cpu.B6, mode=Pin.ALT_OPEN_DRAIN, af=Pin.AF4_I2C1)

With this commit the last print now works:

Damien George fd2ff867a0 stm32/usbdev: Fix calculation of SCSI LUN size with multiple LUNs.
The SCSI driver calls GetCapacity to get the block size and number of
blocks of the underlying block-device/LUN.  It caches these values and uses
them later on to verify that reads/writes are within the bounds of the LUN.
But, prior to this commit, there was only one set of cached values for all
LUNs, so the bounds checking for a LUN could use incorrect values, values
from one of the other LUNs that most recently updated the cached values.
This would lead to failed SCSI requests.

This commit fixes this issue by having separate cached values for each LUN.

Martin Fischer 15574cd665 nrf: Add support for time.ticks_xxx functions using RTC1.
This commit adds time.ticks_ms/us support using RTC1 as the timebase.  It
also adds the time.ticks_add/diff helper functions.  This feature can be
enabled using MICROPY_PY_TIME_TICKS.  If disabled the system uses the
legacy sleep methods and does not have any ticks functions.

In addition support for MICROPY_EVENT_POLL_HOOK was added to the
time.sleep_ms(x) function, making this function more power efficient and
allows support for select.poll/asyncio.  To support this, the RTC's CCR0
was used to schedule a ~1msec event to wakeup the CPU.

Some important notes about the RTC timebase:

- Since the granularity of RTC1's ticks are approx 30usec, time.ticks_us is
not perfect, does not have 1us resolution, but is otherwise quite usable.
For tighter measurments the ticker's 1MHz counter should be used.

- time.ticks_ms(x) should *not* be called in an IRQ with higher prio than
the RTC overflow irq (3).  If so it introduces a race condition and
possibly leads to wrong tick calculations.

Andrew Leech 494bcad8ab stm32/mboot: Disable polling mode by default and use IRQ mode instead.
Polling mode will cause failures with the mass-erase command due to USB
timeouts, because the USB IRQs are not being serviced.  Swiching from
polling to IRQ mode fixes this because the USB IRQs can be serviced between
page erases.

Note that when the flash is being programmed or erased the MCU is halted
and cannot respond to USB IRQs, because mboot runs from flash, as opposed
to the built-in bootloader which is in system ROM.  But the maximum delay
in responding to an IRQ is the time taken to erase a single page, about
100ms for large pages, and that is short enough that the USB does not
timeout on the host side.

Recent tests have shown that in the current mboot code IRQ mode is pretty
much the same speed as polling mode (within timing error), code size is
slightly reduced in IRQ mode, and IRQ mode idles at about half of the power
consumption as polling mode.

downloading firmware is much slower with non-zero timeouts because the host
must pause by the timeout between sending each DFU_GETSTATUS to poll for
download/erase complete.

Andrew Leech 8bbaa20227 stm32/mboot: Implement DFU mass erase.

The erase command can take some time (eg an STM32F765 with 2MB of flash
takes 8 to 10 seconds).  This time is normally enough to make pydfu.py fail
with a timeout.  The DFU standard includes a mechanism for the DFU device
to request a longer timeout as part of the get-status response just before
starting an operation.  This timeout functionality has been implemented
here.

Andrew Leech e4fcd216e0 stm32/usbd_cdc_interface: Remove full==size-1 limitation on tx ringbuf.
Before this commit the USB VCP TX ring-buffer used the basic implementation
where it can only be filled to a maximum of buffer size-1.  For a 1024 size
buffer this means the largest packet that can be sent is 1023.  Once a
packet of this size is sent the next byte copied in goes to the final byte
in the buffer, so must be sent as a 1 byte packet before the read pointer
can be wrapped around to the beginning.  So in large streaming transfers,
watching the USB sniffer you basically get alternating 1023 byte packets
then 1 byte packets.

This commit changes the ring-buffer implementation to a scheme that doesn't
have the full-size limitation, and the USB VCP driver can now achieve a
constant stream of full-sized packets.  This scheme introduces a
restriction on the size of the buffer: it must be a power of 2, and the
maximum size is half of the size of the index (in this case the index is
16-bit, so the maximum size would be 32767 bytes rounded to 16384 for a
power-of-2).  But this is not a big limitation because the size of the
ring-buffer prior to this commit was restricted to powers of 2 because it
was using a mask-based method to wrap the indices.

For an explanation of the new scheme see
https://www.snellman.net/blog/archive/2016-12-13-ring-buffers/

The RX buffer could likely do with a similar change, though as it's not
read from in chunks like the TX buffer it doesn't present the same issue,
all that's lost is one byte capacity of the buffer.

USB VCP TX throughput is improved by this change, potentially doubling the
speed in certain cases.

Damien George 137df81757 stm32/i2cslave: Pass I2C instance to callbacks to support multi I2Cs.
By passing through the I2C instance to the application callbacks, the
application can implement multiple I2C slave devices on different
peripherals (eg I2C1 and I2C2).

This commit also adds a proper rw argument to i2c_slave_process_addr_match
for F7/H7/WB MCUs, and enables the i2c_slave_process_tx_end callback.
Mboot is also updated for these changes.

Damien George 67fd58bbd2 stm32/mboot: Add support for littlefs.
Mboot now supports FAT, LFS1 and LFS2 filesystems, to load firmware from.
The filesystem needed by the board must be explicitly enabled by the
configuration variables MBOOT_VFS_FAT, MBOOT_VFS_LFS1 and MBOOT_VFS_LFS2.
Boards that previously used FAT implicitly (with MBOOT_FSLOAD enabled) must
now add the following config to mpconfigboard.h:

    #define MBOOT_VFS_FAT (1)

Damien George 390f32922d stm32/mboot: Decouple stream, filesystem and top-level loading code.
This commit factors the code for files and streaming to separate source

gzstream interface to make it easier to plug in different filesystems.

Damien George 763bd448a4 stm32/mboot: Don't search for firmware on FS, just attempt to open it.
There's no need to do a directory listing to search for the given firmware
filename, it just takes extra time and code size.  Instead this commit
changes it so that the requested firmware file is opened immediately and
will abort if the file couldn't be opened.  This also allows to specify
files in a directory.

Damien George 81a7293ed6 stm32/mboot: Set VTOR on start up to ensure it has the correct value.
Commit 8675858465 switched to using the CMSIS
provided SystemInit function which sets VTOR to 0x00000000 (previously it
was 0x08000000).  A VTOR of 0x00000000 will be correct on some MCUs but not
on others where the built-in bootloader is remapped to this address, via
__HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH().

To make sure mboot has the correct vector table, this commit explicitly
sets VTOR to the correct value of 0x08000000.

This commit makes the low-level flash C functions usable by code other than
flashbdev.c (eg by mboot).  Changes in this commit are:
- flash_erase() and flash_write() now return an errno error code, a
  negative value on error.
- flash_erase() now automatically locks the flash, as well as unlocking it.
- flash_write() now automatically unlocks the flash, as well as locking it.
- flashbdev.c is modified for the above changes.
