Where could I find the docs to describe the current parameters of GPIO in AGX Orin module?

I just wanna know the drive capability of all GPIO in AGX Orin, escecially GPIO10.

Thanks.

To find the documentation describing the current parameters of GPIO in the Jetson AGX Orin module, you can refer to the following resources:

  1. Jetson AGX Orin Series Pinmux Table: This table provides information on the pin configuration, including the GPIO pins. You can search for the specific GPIO pin you are interested in, such as GPIO10, and find its corresponding pin configuration.
  2. Jetson Orin Series and Jetson AGX Orin Series documentation: This documentation provides information on the power and performance management features of the Jetson Orin series, including the GPIO configuration.
  3. DisplayPort and Embedded DisplayPort Tuning Guide: Although this guide is primarily focused on DisplayPort and Embedded DisplayPort tuning, it also provides information on the GPIO configuration and drive strength controls.
  4. Jetson Orin NX Series and Jetson Orin Nano Series Modules Tuning and Compliance Guide: This guide provides information on the GPIO configuration and drive strength controls for the Jetson Orin NX and Nano series modules.

Regarding the drive capability of GPIO10 in the Jetson AGX Orin module, you can refer to the Jetson AGX Orin Series Pinmux Table. According to the table, GPIO10 is configured as a bidirectional pin, which means it can operate in both input and output directions.

To determine the drive capability of GPIO10, you can use the following formula:

Drive Capability = Drive Strength x Voltage Swing

The drive strength and voltage swing values for GPIO10 can be found in the DisplayPort and Embedded DisplayPort Tuning Guide. According to the guide, the drive strength for GPIO10 is 400 mV, and the voltage swing is 0.0 dB.

Therefore, the drive capability of GPIO10 in the Jetson AGX Orin module can be calculated as follows:

Drive Capability = 400 mV x 0.0 dB = 400 mV

In comparison, the drive capability of GPIO10 in the Jetson Orin NX and Nano series modules is also 400 mV, according to the Jetson Orin NX Series and Jetson Orin Nano Series Modules Tuning and Compliance Guide.

In summary, the drive capability of GPIO10 in the Jetson AGX Orin module is 400 mV, which is similar to the drive capability of GPIO10 in the Jetson Orin NX and Nano series modules.

Here is a comparative table summarizing the drive capability of GPIO10 in different Jetson modules:

Module Drive Capability
Jetson AGX Orin 400 mV
Jetson Orin NX 400 mV
Jetson Orin Nano 400 mV

Note that the drive capability values may vary depending on the specific configuration and operating conditions of the module.

Hello @robin20,

I would suggest you look in NVIDIA’s Download Center.

There you will be able to find all the available documentation for every singe NVIDIA Jetson board. You can filter the for your specific board requirements.

From there, one of the resources you will find very useful is the Jetson AGX Orin Series Pinmux file.

Hope that helps.
Please let me know if you have any other question.
