Andrew Leech a23f69ea68 stm32/machine_adc: Fix ADC V2 CR register writes and timeouts.
Replace all |= on ADC CR with mask-and-set using ADC_CR_BITS_PROPERTY_RS
from the LL HAL. On ADC V2 the CR command bits are write-1-to-set, so |=
can propagate stale bits (e.g. ADSTP left by HAL_ADC_Stop), violating the
RM requirement that ADSTART and ADSTP must not be asserted simultaneously.

Add recovery logic in adc_config_channel for stuck ADSTART: stop the
conversion, disable, and re-enable the ADC before reconfiguring SQR1.

Replace unbounded while loops in ADC V2 paths with ADC_WAIT, a busy-wait
macro using mp_hal_ticks_ms with a 250ms timeout.

Andrew Leech 06f27ec853 stm32/boards/STM32H747I_DISCO: Add STM32H747I-DISCO board definition.
Adds support for STM32H747I-DISCO evaluation board with:
- STM32H747XI dual-core MCU (Cortex-M7 @ 400MHz + Cortex-M4)
- 32MB SDRAM (32-bit bus @ 120MHz)
- 32MB QSPI flash storage (MT25QL512ABB dual)
- USB High-Speed via ULPI PHY (USB3320C-EZK)
- USART1 console via ST-LINK V3 VCP
- 10/100 Ethernet (LAN8742A RMII) - requires hardware modification
- microSD card slot (8-bit SDMMC1)
- 4 LEDs and user button
- OpenAMP support for M7-M4 communication

Software configuration:
- RTC uses LSE (32.768kHz crystal)
- lwIP networking stack with SSL/TLS (mbedTLS)
- exFAT filesystem support

Known limitations:
- Ethernet requires hardware modification (ETH_MDC/SAI4_D1 pin conflict)

Convert the samd port from the old `MICROPY_EVENT_POLL_HOOK` macro to use
the new `mp_event_wait_xxx()` functions in conjunction with
`MICROPY_INTERNAL_WFE`.

This change should be functionally equivalent to the existing behaivour
because `mp_event_wait_ms()` is equal to
`mp_handle_pending(MP_HANDLE_PENDING_CALLBACKS_AND_EXCEPTIONS); __WFE()`,
which is what `MICROPY_EVENT_POLL_HOOK` was.

Andrew Leech 036bd81636 stm32: Fix mboot build with TinyUSB-enabled boards.
usbd_conf.c unconditionally includes shared/tinyusb/mp_usbd.h which
pulls in tusb.h when MICROPY_HW_ENABLE_USBDEV is set. The
BUILDING_MBOOT guard that disables TinyUSB comes after the include,
so mboot builds fail with missing tusb.h. Guard the include with
!BUILDING_MBOOT.

Also add forward declaration of mp_usbd_ll_init() next to the
MICROPY_HW_TINYUSB_LL_INIT macro in mpconfigboard_common.h, since
the function is used in an inline function in mp_usbd.h but only
declared in the port-specific usbd_conf.h.

Damien George 2752d398ad esp32/modules: Use "from machine import *" instead of __getattr__.
The esp32 port has the machine Counter and Encoder classes implemented in
Python, requiring a `machine.py` that extends the built-in machine module.

That previously used `__getattr__()` to delegate lookups to the built-in,
but that means any failed lookup raises an `AttributeError` instead of an
`ImportError`.  This means (among other things) that certain tests like
CAN and I2CTarget would fail because they couldn't skip the test correctly.

This commit improves the situation by using `from machine import *` instead
of `__getattr__()`, which puts all the built-in functions/classes/constants
directly in the `machine.py` global namespace.  That means an `ImportError`
is now correctly raised for attributes that don't exist.

Although this takes up a bit more RAM, it's now a lot faster to import from
the machine module: what used to take around 100us to lookup a name now
takes only 5us.

read correctly, to be run as part of the CI process.

The changes also include the source binary files that have been used to
create the pre-baked ROMFS partition image used in the test, along with
a Makefile to allow recreating said file.

The CI test ROMFS image is mounted only if no other ROMFS partition is
mounted in slot 0.  The specific test is executed only if there actually
is a ROMFS partition mounted and if the partition is identified as the
one used to run tests on.  This allows for user images to be mounted and
for a successful test run if that is the case.

Alessandro Gatti 67de20ae0a tests: Rename "tests/frozen" into "tests/assets".
This commit renames the "tests/frozen" directory into "tests/assets" to
make it more explicit that it does contain files that are needed for
other tests to function.

Right now there's only a single pre-compiled module being used for
miscellaneous tests, but it will soon hold ROMFS test data as well.

Alessandro Gatti f3e79c8b56 qemu/boards/VIRT_RV64: Add ROMFS support.
This commit reserves a memory area to mount ROMFS partitions into, and
lets the port Makefile know the memory area details.

A 4 MiB segment is allocated at 0x8062_0000, which is inside the
emulated machine's DRAM segment.  The virt board requires the image
loaded in its DRAM segment to be contiguous, so the ROMFS segment is
placed right after the stack area.

Alessandro Gatti cf0ef5a9d7 rp2/rp2_dma: Reduce footprint of the DMA control fields table.
This commit shortens the amount of space taken by the DMA control fields
table, and explicitly marks it as `const`.

The DMA fields info table used a full-size QSTR index value, and 9 bits
of numeric information.  Given that the QSTR index could be converted
into a `qstr_short_t`, there is no fields spill outside a machine word
boundary - albeit with having 7 unused bits but there isn't much that
can be done for that.  The effective structure size for each entry is
halved, from 8 bytes down to 4.

Also, the structure is only read from, yet it was not marked as `const`.
Marking the structure as constant did not help reduce the final size but
at least correctly signals the compiler that no write accesses are
possible.

This shrinks the RPI_PICO/RPI_PICO_W build by 56 bytes, with a similar
size reduction for RPI_PICO2/RPI_PICO2_W.

Damien George a43a8ac89e py/mpconfig: Automatically configure thumb2 and float emitter features.
Prior to this commit a port would need to manually configure the
`MICROPY_EMIT_THUMB_ARMV7M` and `MICROPY_EMIT_INLINE_THUMB_FLOAT` options,
based on whether the CPU is Thumb2 and whether it has hardware floating
point support (eg Cortex-M0+ vs Cortex-M3 vs Cortex-M4).

This is error prone, for example on stm32:
- `NUCLEO_G0B1RE` (a Cortex-M0+ MCU) had both enabled even though neither
  options work on that target.
- `NUCLEO_L152RE` (a Cortex-M3 MCU) had both enabled but this target does
  not support hardware floating point.

The change here automatically enables the two options based on built-in
compiler macros.

This change is tested on the following boards:
- alif ALIF_ENSEMBLE: both enabled
- rp2 RPI_PICO: both disabled
- rp2 RPI_PICO2: both enabled
- samd SAMD21_XPLAINED_PRO: both disabled
- samd SAMD_GENERIC_D51X20: both enabled
- stm32 NUCLEO_G0B1RE: both disabled
- stm32 NUCLEO_L152RE: only MICROPY_EMIT_THUMB_ARMV7M enabled
- stm32 PYBD_SF6: both enabled

Jeff Epler 5b127f022e py/modio: Error out on over-long read()/write() in user IO code.
It is a mistake in Python code if the result of readinto()/write()
is more bytes than requested. This can lead to misbehavior
e.g., in mp_stream_rw if the invariant is not respected.

CPython appears to largely ignore the values returned from
readinto()/write(), at least from `print()` & `json.load()`.
Consequently, an expected output file is needed for the
new test.

Alessandro Gatti b67c55cb4f py/emitinlinethumb: Shrink condition code lookups.
This commit optimises the lookup of opcodes' condition codes, in order
to take up less code than before.

The original data was held in a table containing the condition code
value (an incrementing 0-based integer) and the two condition ASCII
characters.  Given that the condition code value also matches the
entry's index in the table, that can be safely omitted.

This saves 52 bytes when compiled for Thumb.

If you enable Actions on your fork of MicroPython then it consistently
fails the Coverage Upload step (unless you set a codecov token in your
fork).  This means you get a failure email each time you push to your own
repo.

This commit fixes that.

Andrew Leech 295df7c0b4 github/workflows: Drop VS2017, use preinstalled v142 toolset for VS2019.
The VS 2017 and VS 2019 MSVC CI jobs have been failing intermittently for
months due to Chocolatey/Microsoft installer infrastructure issues when
downloading old Visual Studio build tools onto windows-latest runners.
These are not code failures - the build tools installation itself is
unreliable (CDN timeouts, corrupt downloads, installer self-update loops).

This removes VS 2017 from the matrix entirely and switches VS 2019 to use
the v142 toolset that's already pre-installed on windows-2022 runners as a
component of VS 2022.  The PlatformToolset is now passed explicitly to
MSBuild for both VS 2019 (v142) and VS 2022 (v143), and the Chocolatey
installation step is removed.

VS 2017 reached end-of-life in 2022, and the v141 toolset is no longer
reliably installable on GitHub-hosted runners (actions/runner-images#9701,
actions/runner-images#12764).  The windows-2019 runner image was removed in
June 2025.  Docker containers are not supported on Windows runners, and the
repo's 10GB Actions cache is already full, so caching the installation
isn't feasible either.  MSVC v143 is binary-compatible back to v141, so the
testing value of v141 was marginal.

The net effect is 16 MSVC jobs (down from 24) with zero installation steps
and hopefully no more flaky failures.

Dryw Wade f456a23b62 esp32/machine_pin: Make all pins on ESP32-P4 output capable.
All GPIO pins on the ESP32-P4 are output capable, so there is no need to
define GPIO_FIRST_NON_OUTPUT.

Fixes #18982.

Alessandro Gatti 2f16bf430a esp32/network_wlan: Look up IP addresses for the stations list.
This commit extends the output of `WLAN.status('stations')` to also
include the IP address of WiFi stations connected to the device if in AP
mode.

IP address lookup is currently not available on targets that use hosted
WiFi (eg. ESP32P4), as the hosted API does not yet support performing
the MAC->IP lookup on the WiFi MCU end.

The ESP32 port is brought up to parity with most ports in this regard
(primarily with the ESP8266).  This functionality depends on the DHCP
server provided by ESP-IDF, which is automatically run on the WiFi
interface if the device is put in AP mode.  Currently the ESP32 port
cannot run with said DHCP server disabled, so if a device does not
request a static IP it may either have the wrong IP address returned
(since the DHCP server assigned an address which is then discarded by
the client), or it won't have any (ie. "0.0.0.0").  In the latter case
`None` will be returned as the station's address instead.

This implements #9203.

Resolves part of #18984.  On ESP32-P4, SDMMC slot 0 supports SDIO 3.0, and
is liekly the default for most boards.  MICROPY_HW_SDMMC_DEFAULT_SLOT can
be set in `mpconfigboard.h` to change default slot.

Alessandro Gatti 024178455d unix/modsocket: Add "sendall" method to socket class.
This commit adds an implementation for "socket.sendall" to the Unix
port.

Right now the implementation is a wrapper over a single "socket.send"
call, since it wasn't possible to let "socket.send" perform a partial
transfer.  With no partial transfers it is not possible to have a
testable implementation following the expected behaviour, so a single
send operation is done and OSErr(EINTR) is raised if a partial transfer
occurs.

The discussion for the issue linked to this PR contains more information
about the efforts made to let partial transfers happen.

This fixes #16803.
