Question
TIM2_ETR not work on PE15
My board (STM32MP135D) useTIM2 to count the external clock.
PE15 cannot work properly, but PA15 works normally.
// ok
tim2_pins_mx: tim2_mx-0 {
pins {
pinmux = <STM32_PINMUX('A', 15, AF1)>; /* TIM2_ETR */
};
};
// not work
tim2_pins_mx: tim2_mx-0 {
pins {
pinmux = <STM32_PINMUX('E', 15, AF1)>; /* TIM2_ETR */
};
};
