I am using the Jetson Nano reference design. I need to know the sysfs name for GPIOS to be able to access them using GPIO Sysfs Interface for Userspace. I looked into the Jetson_Nano_Module_Pinmux_Config_templates.xlsm but could not figure out the GPIO names to use in sysfs. example: GPIO02 is …

hello samir.alami, you may also check the header file for the calculation formulas, i.e. $L4T_Sources/r32.4.3/Linux_for_Tegra/source/public/kernel/kernel-4.9/include/dt-bindings/gpio/tegra-gpio.h #define TEGRA_GPIO(port, offset) \ ((TEGRA_GPIO_PORT_##port * 8) + offset) let’s taking GPI…
