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	d7371124d2	esp32/esp32_common.cmake: Use the tinyusb source files from ESP-IDF. ... This commit removes the explicit dependency on the vendored tinyusb version for the ESP32S2 and ESP32S3 boards. Tinyusb is still available to MicroPython through a dependency on the `espressif/esp_tinyusb` ESP-IDF component, which in turn depends on the `espressif/tinyusb` component itself.

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. This changeset was created using a similar process to decf8e6a8b ("all: Remove the "STATIC" macro and just use "static" instead."), with no documentation or python scripts to change to reflect the new macro name.

Alessandro Gatti	e3c2cf7a04	esp32/esp32_common.cmake: Skip BTree module when requested. ... This commit makes the BTree module truly optional, as it was unconditionally enabled in the shared CMake script for the port.

Alessandro Gatti	fda9bf4917	esp32/esp32_common.cmake: Clean up RISC-V directives. ... This commit cleans up a couple of RISC-V specific directives in the build script. Namely, removes the forced inclusion of the "riscv" component and introduces proper mpy-cross flags. 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).

Angus Gratton	cccac2cc01	rp2,esp32,extmod: Implement UPDATE_SUBMODULES in CMake. ... Rather than having Make calling CMake to generate a list of submodules and then run a Make target (which is complex and prone to masking other errors), implement the submodule update logic in CMake itself. Internal CMake-side changes are that GIT_SUBMODULES is now a CMake list, and the trigger variable name is changed from ECHO_SUBMODULES to UPDATE_SUBMODULES. The run is otherwise 100% a normal CMake run now, so most of the other special casing can be removed. Signed-off-by: Angus Gratton <angus@redyak.com.au>	2025-03-27 17:51:12 +11:00

Keenan Johnson	321b30ca56	extmod/modtls_mbedtls: Wire in support for DTLS. ... This commit enables support for DTLS, i.e. TLS over datagram transport protocols like UDP. 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. This commit is an update to a previous PR #10062. Addresses issue #5270 which requested DTLS support. Signed-off-by: Keenan Johnson <keenan.johnson@gmail.com>	2025-02-14 12:55:25 +11:00
