hello chennasudhakar007,

you should check which pin you’re connected with Jetson-TX2.
please refer to Jetson TX2 Module Pinmux to check the signal name and GPIO numbers.

you could have your implementation in kernel driver to read the GPIO registers by below function.

$TOP/kernel_src/kernel/kernel-4.9/arch/blackfin/include/asm/gpio.h

static inline int gpio_get_value(unsigned int gpio)
