The Artillery Genius Pro ships with an outdated TFT firmware. Upgrading it unlocks better compatibility with this Marlin build and fixes several touchscreen bugs.
Before flashing: the Artillery Genius Pro may ship with either a GD32F305 or an STM32 TFT28 variant. The files provided are for the GD32F305 only. Verify your chip in the TFT About screen before proceeding — the upgrade guide explains how.
