Update to V1.27.0, fix boards and add new boards.

[Josverl]

I found that the example boards did not build anymore due to changes to the upstream micropython/micropython repo

Updated:

• to micropython/micropython @v1.27.0
• the example modules to use static
• the existing boards: CUSTOM_ESP32, CUSTOM_PYBV11, CUSTOM_PYBD_SF2

Added new custom boards for some current hardware

• CUSTOM_RP2040
• CUSTOM_ESP32_C6

Testing

board	built	flashed
CUSTOM_ESP32	Yes	Yes
CUSTOM_ESP32_C6	Yes	Yes
CUSTOM_PYBV11	Yes	-
CUSTOM_PYBD_SF2	Yes	-
CUSTOM_RP2040	Yes	Yes

Thanks for this. Overall it looks good, but I'd like to merge #4 first.

[Josverl]

Thanks, makes sense to work by order.
Feel free to rebase, or just let me know.

There are a few things that I did not yet complete validating:

• checking the documented flashing instructions for all boards
• flashing the pybv11
• I do not have a pybd to test with

[dpgeorge]

I can test PYBD if needed.

This doesn't build for me, on ESP32?

Steps:

git clone git@github.com:micropython/micropython-example-boards.git
cd micropython-example-boards/
git fetch origin pull/5/head:pr5
git checkout pr5
git submodule update --init
make -C lib/micropython/mpy-cross
podman run --rm  -v .:/project:Z -w /project/boards/CUSTOM_ESP32 -e HOME=/tmp espressif/idf:v5.5.3 make -C /project/lib/micropython/ports/esp32 submodules
podman run --rm  -v .:/project:Z -w /project/boards/CUSTOM_ESP32 -e HOME=/tmp espressif/idf:v5.5.3 idf.py  build

The final build step fails with a slew of warnings about Nimble redefinitions, and then compiler errors on extmod/nimble/ that appear related to missing sdkconfig?

I have the same issue with own (much smaller changeset) that updates to 1.27, and I don't see any bluetooth changes in this changeset. Is there anything locally in your tree that hasn't been comitted that we're missing?

lol, esp-idf 5.5.1 works, 5.5.3 fails :) out of time for looking at that.

[karlp]

I don't believe this addresses 4f193132d2de4b4 but that's possibly just by chance that none of the current boards use usb. I've run into this myself while testing my own 1.27 update.
