Elvis Pfutzenreuter	ecbbc512b2	esp32/network_lan: Add PHY_GENERIC device type. ... Support the new PHY_GENERIC device type, added in ESP-IDF v5.4.0 [1]. This PHY driver was added to ESP-IDF to support "generic"/oddball PHY LAN chips like the JL1101, which offer no features beyond the bare 802.3 PHY standard and don't actually need a chip-specific driver (see discussion at [2]).

Rick Sorensen	90aeac800a	esp32/machine_i2c: Fix default I2C pins for C3, S3. ... The default I2C init does not require setting SCL or SDA but the default I2C0 pins for C3, S3 conflict with the espressif GPIO usage. For the C3, pins 18/19 are for USB/JTAG. If used for I2C() they will cause the REPL to hang on initialization of the I2C. For the S3 pin 19 is allocated for USB/JTAG also but the defaults do not seem to affect the REPL. See related #16956.

Daniël van de Giessen	06d8c084b9	esp32/modesp32: Implement esp32.idf_task_info(). ... This adds a new function, `esp32.idf_task_info()`, that can be used to retrieve task statistics which is useful for diagnosing issues where some tasks are using up a lot of CPU time. It's best used in conjunction with the `utop` module from micropython-lib. Signed-off-by: Daniël van de Giessen <daniel@dvdgiessen.nl>	2025-05-16 16:49:59 +10:00

IhorNehrutsa	f48b981567	esp32: Update to use ESP-IDF v5.4.1. ... This version of the IDF uses about 1KB more IRAM and 1KB more DRAM on most boards, but 6.5KB more DRAM usage on the S3.

Damien George	e1ab04e820	esp32/mpthreadport: Fix double delete of tasks on soft reset. ... Python threads (created via the `_thread` module) are backed by a FreeRTOS task. Managing the deletion of the task can be tricky, and there are currently some bugs with this in the esp32 port. The actual crash seen was in FreeRTOS' `uxListRemove()`, and that's because of two calls to `vTaskDelete()` for the same task: one in `freertos_entry()` when the task ran to completion, and the other in `mp_thread_deinit()`. The latter tried to delete the task a second time because it was still in the linked list, because `vTaskPreDeletionHook()` had not yet been called. And the reason `vTaskPreDeletionHook()` was yet to be called is because the FreeRTOS idle task was starved. This commit fixes that. There are three things done by this commit: - remove the `vTaskPreDeletionHook`, it's not needed anymore because task stack memory is allocated by the IDF, not on the MicroPython heap - when a task finishes it now removes itself from the linked list, just before it deletes itself - on soft reset, all tasks are deleted and removed from the linked list in one swoop (while the mutex is held) Signed-off-by: Damien George <damien@micropython.org>	2025-05-16 13:31:34 +10:00

Daniël van de Giessen	3b1e22c669	esp32/network_ppp: Restructure to match extmod/network_ppp_lwip. ... The ESP32 PPP implementation predates the generic implementation in extmod. The new extmod implementation has a few advantages such as a better deinitialisation procedure (the ESP32 implemementation would not clean up properly and cause crashes if recreated) and using the UART IRQ functionality instead of running a task to read data from the UART. This change restructures the ESP implementation to be much closer to the new extmod version, while also bringing a few tiny improvements from the ESP32 version to the extmod version. The diff between extmod/network_ppp_lwip.c and ports/esp32/network_ppp.c is now a small set of easy to review ESP32 port-specific changes.

Alessandro Gatti	2406582479	esp32/network_common: Raise a memory error on ESP_ERR_NO_MEM. ... This commit changes the error handler for WiFi operations to recognise out of memory conditions reported by ESP-IDF functions, and report them as more descriptive exceptions rather than a generic "error 0x101". The error handler only provided a human-readable error description for WiFi-specific error codes (codes in the ESP_ERR_WIFI_BASE range), but WiFi functions are known to return other codes. Now ESP_ERR_NO_MEM is covered with a specific error message, making it easier to debug issues related to running out of ESP-IDF heap.

Daniël van de Giessen	155fa94fbf	esp32/machine_uart: Correctly manage UART queue and event task. ... If the driver was reinitialised while there was already an event task running the queue that task is trying to receive from would be deleted, causing it to try to take a lock that no longer existed and deadlocking the CPU. This change ensures the task is always shut down before recreating the queue and recreates the task afterwards. It also allows setting an IRQ handler before the UART is initialized (like other ports allow), removes the task when the UART is deinitialized (which was previously missing), adds a check that no event task can be started when no queue exists, and adds a check to prevent reinitialising the UART driver unnecessarily.

Alessandro Gatti	883dc41d46	esp32/main: Make the entry point function name configurable. ... This commit introduces a new port configuration entry allowing the entry point function name to be changed, from "app_main" to a custom name. This is needed when MicroPython is embedded as an ESP-IDF component, since the "app_main" symbol is already provided elsewhere, making compilation not possible. Marking MicroPython's symbol as weak would make it compile and make it possible to create and start the MicroPython task anyway with the right FreeRTOS task creation incantation, but it is probably easier to just rename the initialisation function into something else that can be accessed from outside. When MicroPython is embedded as an ESP-IDF component, the MICROPY_ESP_IDF_ENTRY definition can be set to indicate the new entry point function name. The new function name prototype should still be defined in external code to let linking succeed. Also, the NLR failure callback is marked as weak to give the chance of handling such error in a more controlled fashion rather than trigger an unconditional board restart.

Alessandro Gatti	116d0d4945	esp32/esp32_common.cmake: Allow adding defines and compiler flags. ... This commit introduces two extra CMake variables, MICROPY_DEF_COMPONENT and MICROPY_COMPILE_COMPONENT, that make it easier to integrate MicroPython as a custom ESP-IDF component. Whilst there is no official MicroPython component available for ESP-IDF, integration can be achieved with some minor CMake scripting outside the MicroPython tree - except for customisation of compilation defines and build flags, which is what this commit tries to provide. Compilation defines customisation is especially important for MicroPython configuration, as it is not possible to inject a value for MP_CONFIGFILE otherwise. This means that unless MicroPython itself is forked first to edit ports/esp32/mpconfigport.h, it is not possible to perform any meaningful configuration of the interpreter/runtime when included as a component.

Alessandro Gatti	f47e214cdc	all: Rename the "NORETURN" macro to "MP_NORETURN". ... This commit renames the NORETURN macro, indicating to the compiler that a function does not return, into MP_NORETURN to maintain the same naming convention of other similar macros. To maintain compaitiblity with existing code NORETURN is aliased to MP_NORETURN, but it is also deprecated for MicroPython v2.

The "riscv" component is already included by the ESP-IDF build framework, as certain low-level components would not build otherwise, so there is no need to add it to the required components list. The architecture flag for mpy-cross is now set for RISC-V targets, as it was previously set only for Xtensa targets (and it relied on a string comparison rather than using the appropriate configuration variable).

While support for DTLS is absent in CPython, it is worth supporting it in MicroPython because it is the basis of the ubiquitous CoAP protocol, used in many IoT projects. To select DTLS, a new set of "protocols" are added to SSLContext: - ssl.PROTOCOL_DTLS_CLIENT - ssl.PROTOCOL_DTLS_SERVER If one of these is set, the library assumes that the underlying socket is a datagram-like socket (i.e. UDP or similar). Our own timer callbacks are implemented because the out of the box implementation relies on `gettimeofday()`. This new DTLS feature is enabled on all ports that use mbedTLS.
