Determine sys-class-gpio identifier

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX2

Hello,

I use a Jetson TX2 NX.

I would like to view the status of pin number 126 SODIMM (GPIO03,I2S2_DIN,GEN9_I2C_SCL) via /sys/class/gpio/gpioXXX.

I cannot identify the logic allowing me to determine the value of XXX (for pin number 126 SODIMM (GPIO03,I2S2_DIN,GEN9_I2C_SCL)).

Can you tell me the procedure?

Thanking you,

Sincerely,

hello utilisateur3341,

please refer to developer guide, GPIO Changes.
it’s [To check the GPIO number] section with an example to obtain the actual GPIO numbers.
