This should be good to go in now. |
These allow a port to use cmake natively instead of make. Signed-off-by: Damien George <damien@micropython.org>
This commit adds support for building the esp32 port with cmake, and in particular it builds MicroPython as a component within the ESP-IDF. Using cmake and the ESP-IDF build infrastructure makes it much easier to maintain the port, especially with the various new ESP32 MCUs and their required toolchains.

This is really great, and hugely simplifies the ESP32 port, and glad to finally remove the v3/v4 IDF split. Thanks @dpgeorge ! I'm keen to see this merged, but I guess just so that it's recorded somewhere that I can link to, my understanding is that this means that we're temporarily removing support for (wired) LAN and user c modules. In the meantime, v1.14 and v1.13 firmware will still be available with LAN support, and user c modules can be built against the v1.14 tag until a cmake-based replacement is available. Just as a note, is py/mkrules.cmake and py/py.cmake now identical to rp2/micropy_rules.cmake and rp2/micropy_py.cmake? (Separate PR though maybe) |
Yes, correct.
No, they are different. The rp2 versions were actually a precursor to the ones in this PR. The aim is to migrate rp2 to use these new ones (which should improve rp2 build slightly because it'll now support ninja, and other minor improvements). |

This makes no functional change. See similar commit 9aa58cf Signed-off-by: Damien George <damien@micropython.org>
It's now replaced by cmake/idf.py. But a convenience Makefile is still provided with traditional targets like "all" and "deploy". Signed-off-by: Damien George <damien@micropython.org>
IDF v3 is no longer supported with the move to cmake. Signed-off-by: Damien George <damien@micropython.org>
BLE was enabled by default on all boards in the existing make build. Signed-off-by: Damien George <damien@micropython.org>

w00p! Great work @dpgeorge !
BTW, PPP works fine in MP with IDF4, so no idea why it's still being excluded. One of my community members built IDF4 from source (pre cmake) and enabled the PPP stuff and it using it in their project without issue. |
PPP is included now. |
Thanks @dpgeorge ! |
This improves on #6473 and the esp32-idf41-cmake branch. It uses IDF v4.0.2 and converts the esp32 port to fully use cmake and idf.py. Traditional make support is removed. Support for all existing boards is included. WiFi and BLE work.
