What Does "MTK Keypad" Mean in This Context?

In MTK reference designs, the keypad is not just a set of buttons; it is a dedicated hardware interface (KCOL and KROW lines) connected directly to the PMIC or the MTK SoC. When you hear "MTK keypad" in flashing circles, it refers to two things:

  1. Keypad as a trigger – Pressing a specific key combination (e.g., Volume Down + Power) while inserting the USB cable forces the device into Preloader Mode or Bootrom Download Mode.
  2. Keypad driver in firmware – The Android or RTOS firmware uses an MTK keypad driver (mtk-kpd.ko or keypad.c) to scan key events. Flashing a mismatched keymap can brick the keypad.
