!!better!!: Rkpx3 Mcu Update

The Rockchip RK PX3 (often found in "Tesla-style" or vertical screen Android head units) requires a two-part update process: a System (Android) update and a separate MCU (Microcontroller Unit) update. While the system update handles the Android OS, the MCU controls hardware functions like climate control, steering wheel buttons, and radio signals.  Essential Preparation

Breaking Changes (Please Read!)

• PWM Polarity: The default polarity for Timer 4 has been inverted to match the datasheet errata. If your motor controller or LED driver relies on Timer 4, you will need to flip the logic in your device tree.
• ADC Reference: Internal voltage reference drift has been corrected. Your voltage readings will now be 2% more accurate, but legacy code expecting the old (incorrect) value will need recalibration.
