[WIP] zephyr support for iotcloud by andreagilardoni · Pull Request #590 · arduino-libraries/ArduinoIoTCloud

andreagilardoni · 2026-02-25T10:32:50Z

This PR aims to keep track of the effort of adding zephyr support for iotcloud.

This is currently being tested on a portentah7 with zephyr core at version https://github.com/andreagilardoni/ArduinoCore-zephyr/tree/iotcloud-integration-testing

The following PRs are required to be merged:

llext: adding missing time and math functions export arduino/ArduinoCore-zephyr#368 to be included in zephyr_main
variants/portenta_h7: Add support for Analogix ANX7625 MIPI-DSI. arduino/ArduinoCore-zephyr#356: for RAM and Flash expansion
net: arduino: Providing classic arduino class definitions arduino/ArduinoCore-zephyr#380 to be included in zephyr_main

Tasks:

Dependencies:

Zephyr support Arduino_ConnectionHandler#159
Initial zephyr support ArduinoECCX08#84
Zephyr support ArduinoBearSSL#107
Initial zephyr support Arduino_CloudUtils#35
Added zephyr boards in CI ArduinoMqttClient#131 (not strictly required, but adds boards to ci)
Added zephyr boards in CI Arduino_SecureElement#36 (not strictly required, but adds boards to ci)
