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. Signed-off-by: Dryw Wade <dryw.wade@sparkfun.com>	2026-04-08 22:44:03 +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

Damien George	e8a3ee0342	esp32/esp32_common.cmake: Add missing C flags to user C module sources. ... On the esp32 port when adding a user C module, the source code for the user C module was being compiled without certain C flags. Notably the optimisation flag was missing. This commit fixes that by explicitly adding the missing C flags to the compilation of user C modules. The missing flags were the following, which are now included when building user C modules (found by inspecting the generated CMake files when building with ulab): -ffunction-sections -fdata-sections -Wall -Werror=all -Wno-error=unused-function -Wno-error=unused-variable -Wno-error=unused-but-set-variable -Wno-error=deprecated-declarations -Wextra -Wno-error=extra -Wno-unused-parameter -Wno-sign-compare -Wno-enum-conversion -gdwarf-4 -ggdb -mdisable-hardware-atomics -O2 -fmacro-prefix-map=micropython/ports/esp32=. -fmacro-prefix-map=espressif/esp-idf=/IDF -fstrict-volatile-bitfields -fno-jump-tables -fno-tree-switch-conversion See related issue #18880.

Alessandro Gatti	b3d88cf210	extmod/nimble/modbluetooth_nimble: Handle port init failures. ... This commit fixes an issue related to the NimBLE initialisation procedure in low memory environments on ESP32 boards. MicroPython uses at least two different NimBLE stacks across the supported ports, mynewt (imported as an external library), and the one provided by Espressif in their own SDKs. The problem is that these two ports differ in the signature for `nimble_port_init(void)`, with mynewt returning `void`, and Espressif's returning a status code on failure. On ESP32 boards, allocating almost all the available heap and then turning on the Bluetooth stack would trigger a failure in the NimBLE initialisation function that is not handled by the NimBLE integration code, as there's no expectation of a recoverable condition. Since the stack initialisation would progress, then uninitialised memory accesses crash the board. Since we cannot really modify neither mynewt nor Espressif SDKs, the next best thing is to provide two conditional initialisation paths depending on a configuration setting. This would make Espressif ports recover from a failed initialisation whilst retaining the existing behaviour on other ports. This fixes #14293.

robert-hh	2e62b56bdd	ports: Refactor os.urandom(). ... Factor out mp_os_urandom() of each port into extmod/modos.c, which then calls the port-specific function mp_hal_get_random(). Move mp_hal_get_random() to mphalport where suitable. At the MIMXRT and SAMD it is left in modos.c, since there are different implementation depending on the MCU family. At the ALIF, ESP32, CC3200 and RP2 port the file modos.c was removed, since it was empty after moving mp_hal_get_random(). Tested for the cc3200, esp32, esp8266, mimxrt, nrf, rp2, samd, stm32 and unix ports. Compiled for the alif and the renesas port.

Daniël van de Giessen	f02dc6dd8f	esp32/esp32_rmt: Release GIL while waiting for TX done. ... When the timeout parameter of `esp32.RMT.wait_done()` is set to a non-zero value, the underlying `rmt_tx_wait_all_done` blocks (it passes the timeout to `xQueueReceive`).

Matthias Urlichs	a63cc639f2	esp32/mphalport: Actually read from dupterm in mp_hal_stdin_rx_chr(). ... The esp32 port (and esp8266) doesn't read from dupterm in `mp_hal_stdin_rx_chr()` is because it uses `os.dupterm_notify()` instead, which forces a read of the dupterm sources from Python. That function should be called when it's known that there is input to read. Nevertheless, this commit adds code to explicitly poll dupterm in `mp_hal_stdin_rx_chr()`, following other ports like rp2.

But the firmware still exists on the download server, and it makes sense to still keep those old versions available for download, just like all other older versions are still available. This commit introduce a new scheme for `board.json` whereby old variants that are no longer built can be moved to the "old_variants" section.

Testing on a P4 board with C6 WiFi shows there are no regressions for WiFi or BLE. Also rename the `CONFIG_ESP_ENABLE_BT` option to the new `CONFIG_ESP_HOSTED_ENABLE_BT_NIMBLE` option used by the component.

Angus Gratton	4f193132d2	esp32: Remove dependency on esp_tinyusb. ... Instead, depend directly on espressif/tinyusb component (which is otherwise transitively included via esp_tinyusb). Turns out esp_tinyusb builds a bunch of source files with symbols that conflict with our tinyusb symbols (i.e. descriptors_control.c). This only works because nothing in MicroPython causes the linker to include the esp_tinyusb.a library, however in order to override the dcd_int_handler (in following commit) this caused the linker to pull this library in and break the build. There's also a problematic header skew - TinyUSB component was building with the tusb_config.h file from esp_tinyusb component, but we have our own tusb_config.h file in shared/tinyusb. The changes in parent commit allow us to build the TinyUSB component with our tusb_config.h header. User-facing impacts are: - Can no longer override USB VID & PID via sdkconfig, have to set MICROPY_HW_USB_VID/PID instead (changes applied in this commit). - esp32 boards will have the same USB serial number as other ports (i.e. based on the hardware MAC address, not hard-coded).

Fixes problems with USB-CDC state after soft reset if USBDevice has been active with the default USB-CDC driver also enabled. This also brings ESP32 behaviour in line with RP2 and other ports, where boot.py is executed before the runtime USB device is initialised. This allows setting up a custom USB device in boot.py. There is still a bug here, because calling tud_disconnect() doesn't cause any UNPLUG or BUS_RESET events to arrive from TinyUSB - which means the USB device state stays out of sync until we call mp_usbd_init() again...
