The MCU is RA2L1.I encountered a issue when I applied QE for Capacitive Touch( V3.1.0) to make tuning.
At the end, it said

TSCAP voltage error. Please check and review the design of the Target Board.
Failed to tuning.

Does anyone know why?

The TSCAP pin is tied to a capcitor. Is it incorrect?

    On reflection, you are having an issue with tuning, The tuning process is part of QE and the tuning "code" is download TSCAP ( P1.12 on the RA2L1 MCU ) should be connected to ground via a 10nF capacitor. Have you enabled the TSCAP pin in the FSP pin configuration?
