Notes and version constraints

The source lists different controller names; the exact hardware revision must be confirmed before use.
According to the FAQ, programming requires a JLink programmer, not an ST-Link V2.
Image file resolution must match the target display resolution.
Do not move the device during image refresh because the NFC communication distance is limited.
If a refresh fails, remove the reader and reposition it for another attempt.
