How to build PlatformIO based project
|
|
=====================================
|
|
|
|
1. [Install PlatformIO Core](https://docs.platformio.org/page/core.html)
|
|
2. Download [development platform with examples](https://github.com/platformio/platform-raspberrypi/archive/develop.zip)
|
|
3. Extract ZIP archive
|
|
4. Run these commands:
|
|
|
|
```shell
|
|
# Change directory to example
|
|
$ cd platform-raspberrypi/examples/arduino-signed-ota
|
|
|
|
# Build project
|
|
$ pio run
|
|
|
|
# Upload firmware
|
|
$ pio run --target upload
|
|
|
|
# Clean build files
|
|
$ pio run --target clean
|
|
```
|
|
|
|
## 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](https://arduino-pico.readthedocs.io/en/latest/ota.html).
|
|
|
|
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. |
