Nvidia Jetson Xavier Gpio

Here is a spreadsheet which maps the gpio signals back through the carrier board to the module and to the tegra chip itself.

Nvidia jetson xavier gpio. First number is the gpio number within a gpio controller second gpioxxxx is the global linux gpio number 6 16 2020 preliminary. Jetson gpio linux for tegra. Based on the interface and power tree of a given platform the software must write to the correct voltage of these pads to enable interface. The pin source column of the table has details about which gpio pins are sourced directly from the jetson and which ones use an i2c gpio expander for your carrier.

Jetson tx1 tx2 agx xavier and nano development boards contain a 40 pin gpio header similar to the 40 pin header in the raspberry pi. Using the jetson xavier tx2 tx1 gpio pins is primarily done using the linux sysfs for pins directly connected to jetson or i2c read writes for pins using i2c gpio expanders. They can operate at 1 2 volts v 1 8 v or 3 3 v. It benefits from new cloud native support and accelerates the nvidia software stack in as little as 10 w with more than 10x the performance of its widely adopted predecessor jetson tx2.

Jetson agx xavier pins and pads are designed to support multiple voltage levels at a given interface. Last update 7 25 20. The initial pinmux should set all of the these pins except for the power uart rx tx and two i2c busses to gpio at boot. Jetson tx1 tx2 agx xavier and nano development boards contain a 40 pin gpio header similar to the 40 pin header in the raspberry pi.

Jetson gpio linux for tegra. Jetson xavier nx pin 1 is on the outside edge notes. Jetson agx xavier pin 1 notes. You can also now take advantage of cloud native support to more easily develop and deploy ai software to edge devices.

Added the gpiochip specific offset to sysfs gpio number. These gpios can be controlled for digital input and output using the python library provided in the jetson gpio library package. The nvidia jetson xavier nx developer kit brings supercomputer performance to the edge.
