How to make Pin103 default input as High if we give a high voltage to Pin103?

Hi NV_Team,

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?

nvidia@nx:~$ sudo cat /sys/kernel/debug/gpio|grep 478
[sudo] password for nvidia: 
 gpio-478 (                    |cd                  ) in  lo 

From SW point of view, sorry that I have no idea about this.
Not sure when will gpio input state could be changed with corresponding voltage, will discuss internally to see if can provide suggestions to you.

Hi, pin103 is default UART0_RTS pin, also it is ram_code strapping pin. It is not so fit for your use case. You can choose other pin for that based on pinmux sheet.

Hi Trumany,

Ok, thanks for your information.

Hi Trumany,

Pin105 (UART0_CTS) is suite for SD Card Interrupt?
Thanks.

You can try that pin.
