Damien George	7702f7f59d	esp32/main: Update esp_hosted component to latest version 2.7.0. ... This updates the esp_hosted component for ESP32-P4 boards to use the latest version 2.7.0. 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. This change is made partly to work around a current issue with the IDF component manager, that esp_hosted versions after 2.0.17 and prior to 2.7.0 have all disappeared.

Damien George	365cdb6f56	esp32/boards: Enable ESP32P4_REV_MIN_0 option for P4 boards. ... The ESP32-P4 currently comes in three revisions (0.0, 0.1 and 1.0) and all of them are out in the wild. Even though the IDF defaults to a minimum of 0.1 we would like to support as many as possible, so configure MicroPython to work down to revision 0.0. The firmware only grows by 32 bytes when enabling this option. Signed-off-by: Damien George <damien@micropython.org>	2025-12-08 09:48:08 +11:00
Angus Gratton	5ea9a2662d	esp32: Don't disable component manager when updating submodules. ... - Reverts the change from ec527a1 - since later change cccac2cc we no longer exit CMake early to get the submodule list, so it's OK to run component manager during this phase. - Fixes issue where "make submodules BOARD=ESP32_GENERIC_S3" (or any other board that depends on USB) would fail due to missing component(s).

Angus Gratton	eb5d89cd83	esp32/usb_serial_jtag: Flush usb_serial_jtag TXFIFO from ISR. ... This was necessary to un-wedge the USJ TX path on ESP32-P4, I think because the bootloader prints a lot on this chip. I think it might be possible to hit it on other chips, though. The implementation is based on the ESP-IDF driver, which will always add an extra flush when the TXFIFO is empty in case the host is expecting a ZLP. This work was funded through GitHub Sponsors.

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). Side effects include: - CFG_TUD_DWC2_SLAVE_ENABLE is now set, DMA mode is disabled. Signed-off-by: Angus Gratton <angus@redyak.com.au>	2025-11-19 12:12:54 +11:00

Angus Gratton	4766f5680e	esp32: Fix USB deinit/reinit path via soft reset. ... 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...

Elvis Pfutzenreuter	2a3b9b0b4b	esp32/esp32_rmt: Update RMT module to use the new RMT API. ... The current `esp32.RMT` class uses a legacy API from ESP-IDF 4.x. The ESP-IDF 5.x offers a new API, which is overall better, and easier to implement the RX side in the future. This commit updates the module and the documentation, preserving the current MicroPython RMT API as much as possible. The bitstream RMT implementation was updated as well, since ESP-IDF does not allow firmware to reference legacy and new APIs at the same time (it resets right after boot with an error message, even if neither module is imported).

Andrew Leech	aad6ee3d8c	esp32/machine_i2c: Use IDF function for calculating main timeout. ... The esp32 I2C driver sets a global timeout during init. The functionality for this is currently only correct for original esp32 and esp32-s2, newer parts have a slightly different argument which is log-base-2 of the timeout. Note that `i2c_set_timeout()` is a thin layer around `i2c_ll_set_tout()` with the latter writing directly to the hardware register. So the timeout argument passed to `i2c_set_timeout()` needs to be in units calculated by `i2c_ll_calculate_timeout_us_to_reg_val()`.

robert-hh	3546f23143	esp32/machine_i2c: Update to support both v1 and v2 of the IDF driver. ... Support both the legacy ESP-IDF I2C driver (driver/i2c.h) and the new driver/i2c_master.h API for all ESP32-series SoCs. This is controlled by the new config option MICROPY_HW_ESP_NEW_I2C_DRIVER, which is disabled by default. There is a small change to the legacy variant, which shows now as well freq and timeout_us in the print() method. Open issues with the new driver: - No control of the stop=True|False option. stop is always assumed to be True. An issue is raised at the esp-idf repository for it. - Separate call to probe the address at fixed 100kHz. The need is caused by the fact, that NACK on an address is considered as an hard error. According to espressif's issue tracker this is already changed for v6.x and will be backported to earlier versions. So we may see it in a version after V5.5.1 or in a version 5.4.3. There is code in comments to support zero-length writes. Original patch for the v2 driver by Vincent1-python <pywei201209@163.com>.

Angus Gratton	371db85c8e	esp32/machine_uart: Convert machine.UART objects to static instances. ...

Daniël van de Giessen	8c47ff7153	esp32/network_ppp: Correctly clean up PPP PCB after close. ... If PPP is still connected, freeing the PCB will fail and thus instead we should trigger a disconnect and wait for the lwIP callback to actually free the PCB. When PPP is not connected we should check if the freeing failed, warn the user if so, and only mark the connection as inactive if not. When all this happens during garbage collection the best case is that the PPP connection is already dead, which means the callback will be called immediately and cleanup will happen correctly. The worst case is that the connection is still alive, thus we are unable to free the PCB (lwIP won't let us) and it remains referenced in the netif_list, meaning a use-after-free happens later when lwIP traverses that linked list. This change does not fully prevent that, but it *does* improve how the PPP.active(False) method on the ESP32 port behaves: It no longer immediately tries to free (and fails), but instead triggers a disconnect and lets the cleanup happen correctly through the status callback.

A small follow-up to 3b1e22c669, in which the entire PPP implementation was reworked to more closely resemble the extmod version. One of the differences between extmod and the ESP32 port is that the ESP32 port uses the thread-safe API, but in that changeset the PPP input function was accidentally changed to use the non-safe API.
