NOTE:

 Pocket AI’s Thunderbolt 3 port also works with Thunderbolt 4 computers and cables, but continues to operate at Thunderbolt 3 speeds.

# 1.6 Thermal Policy

The GPU core clock throttles at temperatures (T ) past the thresholds shown with the behaviors as listed. Thermal throttling ensures that the highest temperature on the die does not exceed the sense temperature for prolonged periods of time.

NOTE:

 Max.GPU operating temperature is the maximum at which the GPU is guaranteed to operate at target performance (base clock) under total board power level
 THERM\_ALERT generates a 50% (÷2) hardware clock slowdown.
 OVERT generates a 87.5% (÷8) hardware clock slowdown

# 2.4 Linux Driver Installation

Your Pocket AI needs the Linux driver from NVIDIA to function correctly, as well as a small update to your bootloader to support multiple cards.

Before you begin, make sure that you've fully uninstalled an existing NVIDIA drivers from your computer. This tutorial will guide you through updating your bootloader and installing the driver.

![The image displays a digital icon of a white document. The paper has a folded top-right corner and faint grey horizontal lines running across it. Superimposed over the document is a large, bold red checkmark.](.pocket-ai-user-manual-202307/d2548631ab253cf0ef5f69b8c0586f24d8e7c0580c63e9850bf9ae1141c2f001.jpg)
NOTE:

This guide was written for Ubuntu 20.04. Different distributions or versions may require different steps. Consult your support provider or distribution community for additional information.

# To install the Linux driver:

NOTE:

As of this writing, version 525 is the most recent version of the NVIDIA driver tested with Pocket AI. You can check for more recent versions using apt search nvidia-driver-, and replace 525 with the relevant version for your Linux distribution and version.

10.Once the driver has been installed, reboot your computer by typing
sudo reboot
and press the Enter key. Your computer will reboot.

11.Follow the instructions in the next section to verify that Pocket AI is working.

# 2.5 Verifying Linux Driver Installation

To verify that the Linux driver is installed correctly and that your Pocket AI is working properly:

12.Sign in to Ubuntu.

13.Open the Ubuntu settings app, and then select the Thunderbolt menu item. Pocket AI should be listed as ADLINK EGX-TBT-A500.

NOTE:

If you do not see the Thunderbolt menu, you may need to install Thunderbolt support by running sudo apt install bolt in a terminal window. If you still do not see the Thunderbolt options, try starting the Thunderbolt daemon manually by typing boltctl in a terminal window.

14.To verify that the your device is recognized, open a terminal window and type nvidia-smi and then press ENTER. If the device is installed correctly, you will see NVIDIA RTX A500 Embedded GPU listed.
