pjueon/jetson-gpio repository overview

⁠JetsonGPIO(C++)

A C++ library that enables the use of Nvidia Jetson's GPIOs.

• Github repository⁠

Note
The JetsonGPIO library only works properly on Nvidia Jetson devices.

⁠Options

⁠1. Running in privilleged mode

The library determines the jetson model by checking /proc/device-tree/compatible and /proc/device-tree/chosen by default. These paths only can be mapped into the container in privilleged mode.

The following example will run /bin/bash from the container in privilleged mode.

sudo docker container run -it --rm \
--runtime=nvidia --gpus all \
--privileged \
-v /proc/device-tree/compatible:/proc/device-tree/compatible \
-v /proc/device-tree/chosen:/proc/device-tree/chosen \
-v /sys/devices/:/sys/devices/ \
-v /sys/class/gpio:/sys/class/gpio \
pjueon/jetson-gpio /bin/bash

⁠2. Running in non-privilleged mode

You can directly provide your jetson model name to the library through the environment variable JETSON_MODEL_NAME (ex> -e JETSON_MODEL_NAME=JETSON_NANO).
You can get the proper value for this environment variable by running /gpio-cpp/samples/jetson_model in privilleged mode:

sudo docker container run --rm \
--runtime=nvidia --gpus all \
--privileged \
-v /proc/device-tree/compatible:/proc/device-tree/compatible \
-v /proc/device-tree/chosen:/proc/device-tree/chosen \
-v /sys/devices/:/sys/devices/ \
-v /sys/class/gpio:/sys/class/gpio \
pjueon/jetson-gpio /gpio-cpp/samples/jetson_model

The following example will run /bin/bash from the container in non-privilleged mode.

sudo docker container run -it --rm \
--runtime=nvidia --gpus all \
-v /sys/devices/:/sys/devices/ \
-v /sys/class/gpio:/sys/class/gpio \
-e JETSON_MODEL_NAME=[PUT_YOUR_JETSON_MODEL_NAME_HERE] \
