I am connecting a GPIO board which gives low(0) for 5 sec. and high(1) for another 5 sec. repeatedly. But i cant read these values from these pins. Their value is always 1. I guess high(1) is the default value for these pins.
I followed the TX2 Configuring Pinmux GPIO and PAD but I couldnt figure out required changes on Jetson-TX2-Generic-Customer-Pinmux-Template.xlsm file. I have tried to change the “Wake Pin” value to “No” for these pins. Created .cfg files and applied BCT to TX2 but it didnt work. Behaviour was the same.
How should i change the values on the excel file to make these pins work?
I can get input from another 2 GPIO pins:
SOM: GPIO11/AP_WAKE_BT
GPIO (CVB_BT_EN) - GPIO12_BT_EN
Using the following sysfs numbers to listen to ports:
since Wifi is integrated on module instead of carrier board. these two pin might be controlled by wifi driver.
you might refer to [Jetson TX2 Series OEM Product Design Guide] from Jetson Download Center
