Our NX carrier board using Pin103( as SD-Card CD Pin, but in our carrier board this pin is always low voltage.
If plugout SD-Card from slot we test the voltage on Pin103 it’s High with 1.8V but software get Pin103 value is low.
If plugin SD-Card from slot we test the voltage on Pin103 it’s low with 0V and software get Pin103 value is low.
So, NX SOM Pin103(GPIO_PX.06) as input is always lo. How to make Pin103 default input as High if we give a high voltage on Pin103?
