The issue on my board is: GPIO25 is always high when I set it as INPUT mode and use gpio_get_level(25).
I can set GPIO 18, 19 , 22, 23 as INPUT and they works well. But for GPIO25, it is always high. Did I miss anything? any hardware limitation?
Some log from gpio.c is: I think it is right. Please give some advice thanks.
Code: Select all
I (126) gpio: GPIO[25]| InputEn: 1| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0
