override pinMode setting

[ezu00261]

I'm trying to use dial switch on Maix Go. but 'digitalRead(PIN_KEY_UP)' result is -1.

code

#include <Arduino.h>

void setup() {
  Serial.begin(115200);
  pinMode(PIN_KEY_UP, INPUT);
  pinMode(PIN_KEY_PRESS, INPUT);
  pinMode(PIN_KEY_DOWN, INPUT);
}

void loop() {
  Serial.print("UP: "); Serial.print(digitalRead(PIN_KEY_UP));
  Serial.print(", PRESS: "); Serial.print(digitalRead(PIN_KEY_PRESS));
  Serial.print(", DOWN: "); Serial.print(digitalRead(PIN_KEY_DOWN));
  Serial.println("");
  delay(1000);
}

result

> Executing task: platformio device monitor <

--- Miniterm on /dev/cu.usbserial-141301  115200,8,N,1 ---

UP: -1, PRESS: 1, DOWN: 1
UP: -1, PRESS: 1, DOWN: 1
UP: -1, PRESS: 1, DOWN: 1
UP: -1, PRESS: 1, DOWN: 1
UP: -1, PRESS: 1, DOWN: 1
UP: -1, PRESS: 1, DOWN: 1

and i tried next code. (comment out 'pinMode(PIN_KEY_DOWN)') 'digitalRead(PIN_KEY_UP)' result is ok.

code

#include <Arduino.h>

void setup() {
  Serial.begin(115200);
  pinMode(PIN_KEY_UP, INPUT);
  pinMode(PIN_KEY_PRESS, INPUT);
  // pinMode(PIN_KEY_DOWN, INPUT);
}

void loop() {
  Serial.print("UP: "); Serial.print(digitalRead(PIN_KEY_UP));
  Serial.print(", PRESS: "); Serial.print(digitalRead(PIN_KEY_PRESS));
  // Serial.print(", DOWN: "); Serial.print(digitalRead(PIN_KEY_DOWN));
  Serial.println();
  delay(1000);
}

result

i think so 'pinMode(PIN_KEY_DOWN, INPUT)' was override 'pinMode(PIN_KEY_UP)' setting.
