Damien George	2a0e2b5782	esp32/main: Auto detect the size of flash and auto create vfs partition. ... Currently in the esp32 port the size of the SPI flash must be configured at build time, eg 4MiB, 8MiB, etc. Also, the esp32 partition table must be configured at build time, which depends on the size of the SPI flash. A bigger flash means more can be allocated to the user filesystem. This commit makes it so the SPI flash size is automatically determined at runtime, and the filesystem size is automatically set to take up as much room as possible (a "vfs" partition is created automatically if it doesn't exist). This works by: - Setting the SPI flash size to be 4MiB in the build (or some other value, as long as the firmware app fits). - Removing the vfs partition from the esp32 partition table (only nvs, phy_init and firmware, and maybe romfs, remain in the partition table). - At boot, query the physical size of the SPI flash and use that as the actual size in the code. - If it doesn't already exist, automatically create a "vfs" partition which takes up the flash from the end of all existing partitions to the end of flash. This allows simplifying a lot of board configurations, and removing some board variants that just change the flash size (to be done in a following commit). It's also fully backwards compatible, in the following sense: - Existing boards with MicroPython firmware will continue to work with the same filesystem, ie the filesystem won't be erased when the firmware is updated. - If a user has a custom esp32 partition table and installs MicroPython as a bare app into the app partition, the new MicroPython firmware will honour the esp32 partition table and use either "vfs" or "ffat" partitions as the filesystem.

purewack	5f058e9863	esp32: Update ADC driver update to the new esp_adc API. ... This commit updates the ADC to use the new driver `esp_adc/adc_oneshot.h`. There are several errata notes about not being able to change the bit-width of the ADCs certain chips. The only chip that can switch resolution to a lower one is the normal ESP32. ESP32 C2 and S3 are stuck at 12 bits, while S2 is at 13 bits. On the S2, you can change the resolution, but it has no effect on the resolution, rather, it prevents attenuation from working at all! The resolution is set to the maximum possible for each SoC, with the ESP32 being the only one not throwing errors when trying to set the bit-width to 9, 10, 11 or 12 bits using `ADC.width(bits)`.

Daniël van de Giessen	2c2f0b292a	esp32: Re-use allocated timer interrupts and simplify UART timer code. ... If the interrupt is not freed but merely disabled, instead of reallocating it every time the timer is enabled again we can instead just re-enable it. That means we're no longer setting the handler every time, and we need to ensure it does not change. Doing so by adding an additional wrapper function does not only solve that problem, it also allows us to remove some code duplication and simplify how machine_uart uses the timer.

Daniël van de Giessen	bf909303ff	esp32/machine_timer: Do not free interrupt from ISR. ... esp_intr_free is not safe to call from the timer ISR because it requires the current task (the one the ISR interrupted) to be pinned to the same core as the interrupt was allocated on. Merely disabling the ISR however is safe since that only requires that we're currently running on the same core (which the ISR always is), regardless of the current task. This was causing deadlocks in machine_uart when the ISR happened to interrupt a task that was not pinned to a specific core.

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.

Damien George	0255cb77cc	esp32: Implement vfs.rom_ioctl with support for external flash. ... Not enabled by default on any board. For a board to enable ROMFS it must: - Add `#define MICROPY_VFS_ROM (1)` to its `mpconfigboard.h` file. - Use `partitions-4MiB-romfs.csv` as its partitions file (or a similar partitions definition that has an entry labelled "romfs").
