Andrew Leech	9ca3b7412e	stm32/usbd_conf: Fix USB VBUS sensing for newer STM32F4/F7 HAL versions. ... Newer STM32F4/F7 variants (and their HAL headers) use a single USB_OTG_GCCFG_VBDEN register bit for VBUS detection instead of the older NOVBUSSENS/VBUSASEN/VBUSBSEN bits. The existing TinyUSB VBUS sensing code only handles the older register layout, so boards with the newer HAL silently skip VBUS configuration. This adds a #if defined(USB_OTG_GCCFG_VBDEN) branch that enables or disables VBUS detection via the new register bit, falling through to the existing code for older variants.

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.

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.

Alessandro Gatti	c895770d4a	tests/ports/qemu: Add ROMFS tests to CI. ... This commit adds a new test to make sure ROMFS files are mounted and 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. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2026-04-15 16:04:26 +10:00

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. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2026-04-15 16:03:38 +10:00
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 - stm32 PYBV10: both enabled Signed-off-by: Damien George <damien@micropython.org>	2026-04-15 15:49:44 +10:00

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. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2026-04-08 22:04:55 +10:00

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.
