Notes

This examples showcases the usage of signed Over-The-Air (OTA) updates with the Raspberry Pi Pico W.

The difference to regular OTA updates is that update binaries are signed using the private.key to produce a firmware.bin.signed file.

The firmware then uses the public.key file to verify the signature on the binary it receives in an OTA update. It will reject OTA update binaries that were not properly signed.

For more details, see the documentation.

For the initial firmware update, use the rpipicow_via_usb environment.

Then, open the serial monitor and note down the IP of the Pico that it outputs.

Use this IP as the upload_port in the rpipicow_via_ota environment and use the "Upload" project task there.
