all: Bump version to 1.26.0-preview. Signed-off-by: Damien George <[email protected]>
ROMFS, alif port, RISCV inline assembler, DTLS, mpremote recursive re… …move After more than three years in development, the "ROMFS" feature has been finalised, its filesystem format specified, and the VFS driver and supporting code are included in this release of MicroPython. This feature builds on bytecode version 6 (available for many years now), which supports executing bytecode in-place, that is, without the need to copy it to RAM. ROMFS defines a read-only, memory-mappable, extensible filesystem that can contain arbitrary resources, including precompiled mpy files, and allows executing bytecode directly from the filesystem. This makes importing significantly faster and use a lot less memory. Also, data resources such as fonts can be used in-place on a ROMFS without loading into RAM. ROMFS is currently enabled only on selected boards: PYBD-SFx, all alif-port boards, a new ESP8266_GENERIC variant called FLASH_2M_ROMFS, and all stm32 Arduino boards. Other boards will have ROMFS enabled in the future, or it can be manually enabled on user-defined boards. To build and deploy a ROMFS, mpremote has a new `mpremote romfs` command, with "query", "build", and "deploy" sub-commands, which can build and deploy a directory structure to a ROMFS partition on a target device. These initial ROMFS features will be extended in the future, but for now they provide a way to try out this long-anticipated feature. This release also introduces a brand new "alif" port supporting Alif Ensemble MCUs. These MCUs offer multiple ARM cores, including Ethos-U55 machine-learning processors, and a comprehensive set of peripherals. Current features of the MicroPython alif port include USB support via TinyUSB, dual-core support using OpenAMP, octal SPI flash with XIP, the machine classes Pin, UART, SPI and I2C, and cyw43 WiFi and BLE support. Two alif board definitions are currently available: ALIF_ENSEMBLE for the official Alif Ensemble E7 DevKit, and OPENMV_AE3 for OpenMV's upcoming AE3-based camera board. MicroPython's inline assembler now supports 32-bit RISC-V assembly code via the newly implemented `@micropython.asm_rv32` decorator. This allows writing small snippets of RISC-V machine code that can be called directly from Python code. It is enabled on the rp2 port when the RP2350 is running in RISC-V mode. Datagram TLS (DTLS) is now supported by the `tls` module and enabled on the alif, mimxrt, renesas-ra, rp2, stm32 and unix ports. An `SSLContext` can be created in DTLS mode using `tls.PROTOCOL_DTLS_CLIENT` or `tls.PROTOCOL_DTLS_SERVER` as the mode option, and this context can then be used to wrap a normal UDP socket to get a secure UDP connection. The mpremote command-line tool now supports recursive remove via the new `rm -r` option; for example, `mpremote rm -rv :` can be used to remove all files and directories in the current working directory of the target device. mpremote also now supports relative URLs in the `package.json` file, installing from the local filesystem, and has optimised readline support in `mpremote mount`. Improvements to the core interpreter include: full support for tuples and start/end arguments in the `str.startswith()` and `str.endswith()` methods; enabling of the two-argument version of the built-in `next()` function on most of the ports; a new `sys.implementation._build` entry which holds the build name of the target; and `vfs.mount()` with no arguments now returns a list of mounted filesystems. The `marshal` module has been added with `dumps()` and `loads()` functions, which currently support code objects and, in combination with `function.__code__`, allow converting functions to/from a bytes object. This module is not enabled by default but can be used in custom build configurations. The MicroPython native linker `mpy_ld.py` now includes support for linking in static libraries automatically. This allows the native-module build scripts to look for required symbols from libraries such as `libgcc` and `libm` that are provided by the compiler. This now makes it possible to use standard C functions like `exp()` in native modules. Also, native modules now support 32-bit RISC-V code. The esp32 port now supports IDF v5.3 and v5.4, and support for versions below v5.2.0 has been dropped. Dynamic USB device support is now enabled on ESP32-S2 and ESP32-S3 MCUs, allowing configuration of the USB device at runtime. I2S has been enabled on all ESP32-C3 boards, the `Pin.toggle()` method has been added, and the I2C bus identifier is now an optional argument (by default, bus 0 is used). Additionally, memory management has been improved for the allocation of TLS sockets to attempt to automatically free any existing unused TLS memory when needed. The mimxrt port now enables exFAT filesystem support and the PPP driver for boards with lwIP networking, and has support for a UF2 bootloader, making it easier to deploy firmware. The `machine.RTC.now()` method has been dropped (use `datetime()` instead), `ADC.read_uv()` has been added, and `machine.I2C` has support for the `timeout` keyword argument. The I2C, SPI and UART classes now support default buses, so the first argument to these constructors is no longer needed if the default bus is used. Some inconsistencies with PWM output have been fixed, along with an allocation bug for the UART RX and TX buffers. The rp2 port sees the introduction of many new RP2350 boards, including the Pico 2 W, as well as support for PSRAM with size autodetection. The PIO interface now supports `side_pindir` selection, and SPI allows the MISO pin to be unspecified. Both the I2C and SPI classes now have the bus identifier as an optional argument with a default based on the board configuration. WPA3 is now supported on the Pico W and Pico 2 W in both AP and STA modes. Lost WiFi events due to code executing on the second core have now been fixed, mDNS has been fixed, and `rp2.bootsel_button()` and USB sleep now work on RP2350. ROMFS support has been added but is not enabled on any board by default; see commit 50a7362 for information on how to enable it manually. The samd port has added full support for 9-bit data in the UART peripheral and supports default buses and pins for I2C, SPI and UART. DAC for two channels has been fixed on SAMD51, and UART buffering has had a few bug fixes. The stm32 port now deinitialises I2C and SPI buses on soft-reset, which may be a breaking change for certain applications; be sure to always initialise I2C and SPI instances when creating them. The CAN code has been refactored, and a few minor bugs have been fixed there. Corrupt littlefs filesystems are now handled properly at startup: instead of a failed mount leading to a hard fault, the code attempts to mount again with default block device parameters, and if that also fails, it prints a message and continues the boot process. ROMFS is enabled on PYBD-SFx boards and all Arduino boards and can be enabled on other boards by manual configuration; see commit bea7645 for details. The PYBD-SF6 firmware now supports both original boards and new boards with larger SPI flash. WPA3 is now supported on boards using the cyw43-driver. mboot now includes a version string which is placed at the very end of the flash section allocated for this bootloader (usually 32k); this version can be retrieved using the `fwupdate.get_mboot_version()` function. The zephyr port has had `machine.Timer` and `machine.WDT` implemented. New boards added in this release are: ALIF_ENSEMBLE and OPENMV_AE3 (alif port), MAKERDIARY_RT1011_NANO_KIT (mimxrt port), MACHDYNE_WERKZEUG, RPI_PICO2_W, SEEED_XIAO_RP2350, SPARKFUN_IOTNODE_LORAWAN_RP2350, SPARKFUN_IOTREDBOARD_RP2350, SPARKFUN_PROMICRO_RP2350, SPARKFUN_THINGPLUS_RP2350, SPARKFUN_XRP_CONTROLLER, SPARKFUN_XRP_CONTROLLER_BETA and WEACTSTUDIO_RP2350B_CORE (rp2 port), ADAFRUIT_NEOKEY_TRINKEY, ADAFRUIT_QTPY_SAMD21, SAMD_GENERIC_D21X18, SAMD_GENERIC_D51X19 and SAMD_GENERIC_D51X2 (samd port), WEACT_F411_BLACKPILL (stm32 port). The change in code size since the previous release for select builds of various ports is (absolute and percentage change in the text section): bare-arm: +4 +0.007% minimal x86: -90 -0.049% unix x64: +16941 +2.046% stm32: -96 -0.025% cc3200: +280 +0.152% esp8266: +964 +0.138% esp32: +10956 +0.654% mimxrt: +7508 +2.065% renesas-ra: -160 -0.026% nrf: +168 +0.090% rp2: +7944 +0.872% samd: +1112 +0.418% The leading causes of these changes in code size are: - minimal, stm32, renesas-ra: various small code-size optimisations - unix: enable VfsRom, update mbedTLS to v3.6.2, enable DTLS - cc3200: implement `Pin.toggle()` method - esp8266: enable function attributes, implement `Pin.toggle()`, allow enumerating connected stations in AP mode, update requests package - esp32: lots of small fixes and improvements - mimxrt: enable exFAT, add `function.__code__` and function constructor - nrf: various small features such as `sys.implementation._build`, two-argument built-in `next()`, no-argument `vfs.mount()` - rp2: update mbedTLS to v3.6.2, enable DTLS, update cyw43-driver to 1.1.0 - samd: support UART 9-bit data, add `function.__code__` and function constructor, provide default IDs for UART, I2C and SPI Performance of the VM and runtime is effectively unchanged since the previous release.

RP2350 and ESP32-C6 support, RISC-V native emitter, common TinyUSB code This release of MicroPython adds support for the new RP2350 MCU, improved RISC-V support with native code generation, support for ESP32-C6 MCUs, update Zephyr version with threading support, unified TinyUSB bindings across ports, a portable UART IRQ API, and enhanced mpremote recursive copy. There are also numerous bug fixes, enhancements to the test suite and more attention to testing of the machine module and its API. Read on for more details. Support for the RISC-V architecture has been significantly extended, to include an RV32IMC native code emitter, native NLR and GC register scanning implementations for 32- and 64-bit RISC-V, support for placing RV32IMC native code in .mpy files and also freezing it, and RISC-V semihosting support. Testing for RISC-V is done with the qemu and unix ports, and the support is utilised in the esp32 and rp2 ports. There is now support concatenation of adjacent f-strings, as well as raw f-strings. There is also a new `micropython.RingIO` class which provides a stream interface to an efficient, thread-safe, byte-oriented ring-buffer implementation. All the ports that use TinyUSB have now been unified to use the same shared helper code for CDC serial. This includes: esp32 (S2 and S3), mimxrt, renesas-ra, rp2 and samd ports. With this has come the useful feature that the startup CDC serial data is buffered and then sent to the host upon connection. This means that (among other things) the REPL banner and initial prompt is now seen on first connection to a board. Most ports now support registering Python callbacks for UART IRQs, and the semantics for the callback are made as consistent as possible across the ports. The possible IRQs are IRQ_RX, IRQ_RXIDLE, IRQ_TXIDLE and IRQ_BREAK, and the ports that have added support for these are esp32, mimxrt, nrf, renesas-ra, rp2 and samd (stm32 already had this feature). In the networking sub-system, a new API for configuring IP addresses and related settings has been added: the global `network.ipconfig()` function, and a `nic.ipconfig()` method on individual network interfaces. This new API supports both IPv4 and IPv6, with much more control compared to the original `nic.ifconfig()` method; the latter is still available for backwards compatibility, but `ipconfig()` is now preferred moving forward. A portable `network.PPP` implementation has been added, based on lwIP. This is not enabled by default but can be added to custom boards that use bare-metal lwIP. The `machine.SoftSPI` class now supports least-significant-bit (LSB) mode, as well as the existing MSB mode. The behaviour of `sys.exit()` and `raise SystemExit` (which are equivalent) has been changed: previously this would terminate the running script and drop to the REPL, but now it terminates the running script and triggers a soft reset of the device. This is more consistent with the unix port, which exits completely on a `SystemExit` exception. This change in behaviour is a breaking change and may impact certain applications; see commit 69c25ea for details. The mpremote tool has a new hashing ability, eg `mpremote sha256sum <file>` and also has enhanced recursive copy which first checks the hash and only updates the destination file if the hash is different. This makes copying a large directory to a device significantly faster, and enables a "sync" workflow, where small changes can be made to a large application and then quickly deployed to the device via the recursive copy. The esp32 port now supports ESP-IDF v5.2.2, and with this comes support for ESP32-C6 MCUs. The RISC-V native emitter has been enabled on C3 and C6 MCUs. There have also been some important bug fixes, for handling of native code loaded from .mpy files, fixes for stack corruption, and a fix to I2S, among other things. Also, applications that use many TCP sockets in quick succession should see an improvement because there is now a hard limit on the number of active TCP sockets. The qemu port has been renamed from qemu-arm to simply qemu, and now supports both ARM and RISC-V architectures. It has also been reworked to provide a REPL and to run tests via a pty serial port, emulating how tests are run on bare-metal targets. The rp2 port has updated pico-sdk to v2.0.0, which brings support to MicroPython for the new RP2350 MCU, in both ARM and RISC-V mode, and in both the 30- and 48-pin variants. IPv6 has been enabled by default on this port, and optional `network.PPP` made available. The USB now remains active during `machine.lightsleep()`, and there have been many bug fixes. The stm32 port also sees optional `network.PPP` support through lwIP, and support for octospi on STM32H7 MCUs. A build option has been added to put IRQ, flash and UART code in RAM, and this feature is enabled on boards with a UART REPL, to allow filesystem access to work on these boards without losing UART characters (eg when using mpremote to copy files to a board). Preemptive keyboard interrupt via PendSV has been removed: this was buggy and no longer necessary; see ece950d for details. The ARDUINO_PORTENTA_H7 and ARDUINO_NICLA_VISION boards have added support for the NXP SE05x secure element, with integration in mbedTLS. The webassembly port has better asyncio support, including the ability to do a top-level await of `Task` and `Event` objects. There has also been enhancements to the proxying of objects between JavaScript and Python. The zephyr port has updated to use Zephyr v3.7.0, threading has been implemented through the `_thread` module, the REPL now operates in non-blocking mode so it can process events/callbacks, some more Python features including big-integers have been enabled, and machine objects (eg Pin, I2C) can now be constructed using device-tree node labels. New boards added in this release are: ESP32_GENERIC_C6, M5STACK_ATOMS3_LITE, M5STACK_NANOC6, OLIMEX_ESP32_EVB, UM_FEATHERS3NEO, UM_OMGS3, UM_RGBTOUCH_MINI and UM_TINYC6 (esp32 port), RPI_PICO2 (rp2 port), ARDUINO_OPTA (stm32 port). The change in code size since the previous release for various ports is (absolute and percentage change in the text section): bare-arm: +116 +0.203% minimal x86: +185 +0.100% unix x64: +8994 +1.098% stm32: +1028 +0.263% cc3200: +1152 +0.625% esp8266: +2968 +0.426% esp32: -53617 -3.101% mimxrt: +1864 +0.513% renesas-ra: +1536 +0.245% nrf: +1460 +0.781% rp2: +3592 +1.068% samd: +2244 +0.845% The leading causes of these changes in code size are: - bare-arm, minimal: fix `int.to_bytes()` buffer size checks - unix: enable GCM and ECDHE-RSA in mbedTLS config - stm32: add new `RingIO` class - cc3200: add `network.ipconfig` and `WLAN.ipconfig` - esp8266: add `network.ipconfig`, `WLAN.ipconfig` and `RingIO` class - esp32: update ESP-IDF from v5.0.5 to v5.2.2 - mimxrt, renesas-ra, nrf, rp2, samd: `RingIO` class and `UART.irq` support Performance is effectively unchanged since the previous release on all ports, except the unix port which sees some reduction in GC times due to no more root-pointer scanning of executable memory.

Dynamic USB devices, revamped webassembly port, openamp, tls, vfs mod… …ules This release of MicroPython adds support for dynamic USB devices defined in Python, adds new `openamp`, `tls` and `vfs` modules, completely revamps the webassembly port to add proxying between JavaScript and Python, and implements significant code size optimisations for frozen modules. There are also many other enhancements and bug fixes. Keep reading for a more detailed summary of the main changes. After a lot of design, development and testing, MicroPython now has full support for user-defined USB devices. The interface is via a new `machine.USBDevice` class, and this allows the user to specify the USB descriptors and implement Python callbacks for USB endpoint transfers. With this, any USB device can be implemented in pure Python. While the `machine.USBDevice` interface is low-level and complete, there is a higher-level USB library in `micropython-lib` that allows easier implementation of devices, with examples for keyboard, mouse, MIDI and serial CDC. This feature is currently available on rp2 and samd ports, and other ports will follow in the future. Support for the OpenAMP (asymmetric multiprocessing) protocol has been added through the new `openamp` module. This allows MicroPython to control other CPU cores in the system, to load and start processes and communicate with them through endpoints. This feature is currently available on the mimxrt and stm32 ports. Two other new modules have been added: `vfs` and `tls`. The `vfs` module contains all VFS (virtual filesystem) related functions and classes, such as `mount`, `umount` and `VfsFat`. These were originally in the `os` module but having them there is not compatible with CPython, so they have been moved to their own dedicated module. They still exist in the `os` module for now but will eventually be removed from there, so it's recommended to start using the `vfs` module from now on. Similarly the new `tls` module is an evolution of the `ssl` module, whereby all the existing functionality in `ssl` has been moved to the `tls` module. This is done because MicroPython's SSL interface is becoming increasingly different to CPython's and moving this SSL/TLS functionality to a new `tls` module gives it room to grow and obtain new features that are useful for embedded applications. And compatibility with normal Python is still retained via a pure Python implementation of the `ssl` module. One new feature in the new `tls` module is the ability to register a certificate verification callback. Other additions include more methods on the `deque` object so it is doubly-ended and supports iteration, and support for half-float 'e' format in `struct.pack`/`struct.unpack`. Dynamic native modules have had some additional runtime methods exposed, and the .mpy sub-version has been increased from v6.2 to v6.3 (native code in .mpy files will need to be recompiled, but bytecode does not and is still compatible). There has also been significant code size optimisations for frozen modules. A new internal `mp_proto_fun_t` type has been defined which allows the common case of bytecode functions (as opposed to native code) to be stored in frozen code without any additional overhead of the `mp_raw_code_t` descriptor structure. All firmware builds using frozen modules will see a significant decrease in size. Code size has also improved further for very small targets by adding an option to remove the qstr hash bytes. Internally in the source code the "STATIC" macro definition has been removed. Code should now just use "static" instead. If you have C/C++ code that uses "STATIC" then either replace it with "static", or provide your own #define to define "STATIC" as "static". See commit decf8e6 for details. Mbedtls has been updated to version 3.5.1. And network interface constants, such as `IF_STA` and `SEC_WPA2`, have now been consolidated across ports so they all live at the `WLAN` class level, for example `network.WLAN.SEC_WPA2` (existing constants at the `network` module level have been retained for backwards compatibility, but the new ones should be preferred from now on). The esp32 port has seen some important bug fixes in the BLE component, to deinitialise without crashing, and increase the BLE task stack size. This port also uses the new I2S IDF driver, and supports IDF 5.0.5 and 5.2. There is support to enter the bootloader via `machine.bootloader()` and a new `esp32.mcu_temperature()`, for ESP32-C3/S2/S3 devices. The rp2 port has added the new `machine.USBDevice` dynamic USB driver, and has had firmware performance optimisations applied to critical parts of the runtime and VM, giving about a 10% performance boost. There is now direct memory access to PIO and SPI FIFOs via proxy arrays, and bugs have been fixed with threads, lightsleep and UART IRQ latency. The stm32 port has integrated support for the new `openamp` module, which is enabled on all Arduino boards. And firmware for Arduino boards now freeze in additional Arduino-specific library code. There have been fixes for internal flash writes on STM32H5 and STM32H7 MCUs (bank selection and flashing of the last word in a buffer), an important fix to a SPI DMA caching bug, an I2C clock enable fix for I2C4 on STM32F7 MCUs, and a fix for the FDCAN source clock frequency on STM32G4 MCUs. Mboot has added support for a new raw filesystem, to allow simpler and more robust firmware updates. The webassembly port has seen a significant overhaul in its structure, and is now built as a JavaScript .mjs module that exports a user-friendly JavaScript-level API which is inspired by the API provided by Pyodide (which is a version of CPython that runs in the browser). This change is motivated by the need to use MicroPython as an engine within Pyscript, which is a platform for Python in the browser. New features in the webassembly port include proxying of objects between Python and JavaScript, a `js` module to interface with the JavaScript namespace, a `jsffi` module for miscellaneous proxy helpers, top-level async code, JavaScript driven asyncio support, automatic growing of the Python heap, integration of JavaScript and Python finalisation for global memory management, more `time` module functions, and support for build variants (following the unix port). The change in code size since the previous release for various ports is (absolute and percentage change in the text section): bare-arm: -220 -0.383% minimal x86: -341 -0.184% unix x64: +20168 +2.527% stm32: -1692 -0.430% cc3200: +256 +0.139% esp8266: -8880 -1.260% esp32: -3328 -0.194% mimxrt: -408 -0.112% renesas-ra: -464 -0.074% nrf: -640 -0.341% rp2: +5380 +1.626% samd: +3224 +1.229% The leading causes of these changes in code size are: - bare-arm, minimal: disabling qstr hashing - unix: updating mbedtls to version 3.5.1 - stm32: optimising size of frozen modules - cc3200: addition of new `vfs` module, and bug fixes in the VM and array type - esp8266: disabling unused `MICROPY_DEBUG_PRINTERS` and optimising frozen modules - esp32, mimxrt, renesas-ra, nrf: optimising frozen modules - rp2: addition of `machine.USBDevice`, enabling -O2 optimisations - samd: addition of `machine.USBDevice` Performance is effectively unchanged since the previous release on all ports, except the rp2 port which sees a performance improvement of roughly 10%.
