Note1 : (Optional) Hardware time synchronization is recommended for universal time stamping. [DRIVE PX2 TIME SYNC GUIDE - FAQ - NVIDIA Developer Forums](https://devtalk.nvidia.com/default/topic/1031778/faq/nvidia_drive_px2_time_sync_guide/)  
Note2 : Aurix CAN needs 120ohm termination.

## By using Aurix-FW, DrivePXApp and EasyCan following the steps below EASYCAN Testing (connect your device to a CAN interface, for example, CAN1/CANa) Note: for Step 1 – 3, you need only to do once.

## Step 1 : create a EB user on target nvidia@nvidia:~$ sudo su - root@nvidia:~# adduser eb Adding user `eb' ... Adding new group `eb’ (1001) …cd Adding new user `eb' (1001) with group `eb’ … Creating home directory `/home/eb' ... Copying files from `/etc/skel’ … Enter new UNIX password: eb Retype new UNIX password: eb passwd: password updated successfully Changing the user information for eb Enter the new value, or press ENTER for the default Full Name : eb Room Number : Work Phone : Home Phone : Other : Is the information correct? [Y/n] Y root@nvidia:~#

## Step 2 : Copying DrivePXApp and EasyCan Config to target root@nvidia:~# mkdir /etc/eb Copy LINUX\_LXTHREADSX86\_DrivePxApp.elf to ‘/home/nvidia/’ Copy EasyCanConfigFile.conf to ‘/etc/eb/’ Copy DrivePxApp.conf to ‘/etc/eb/’

Step 3 : Edit the DrivePxApp.conf file. Accordingly (if you only test one target, skip the other)

On Tegra A :  
cd /etc/eb  
root@nvidia:/etc/eb# vi DrivePxApp.conf  
AurixIP=10.42.0.146  
TegraID=A  
root@nvidia:/etc/eb#

## On Tegra B : cd /etc/eb root@nvidia:/etc/eb# vi DrivePxApp.conf AurixIP=10.42.0.146 TegraID=B root@nvidia:/etc/eb#

Step 3.1 : Edit the EasyCanConfigFile.conf file. Accordingly if you’d like to change the message IDs of each CAN interface (if you only test one target, skip the other)

On Tegra A :  
cd /etc/eb  
root@nvidia:/etc/eb# vi EasyCanConfigFile.conf  
…  
root@nvidia:/etc/eb#

## On Tegra B : cd /etc/eb root@nvidia:/etc/eb# vi EasyCanConfigFile.conf … root@nvidia:/etc/eb# We created a sample script (create\_sample\_conf.sh) to generate 120 CAN IDs for CAN A. You can copy the script to /etc/eb and run it. root@nvidia:/etc/eb# ./create\_sample.conf.sh

Step 4 : Recieve transmitted messages on target

## On Tegra (A and B): use LINUX\_LXTHREADSX86\_DrivePxApp.elf to check if the EasyCan config is received by Aurix root@nvidia:/etc/eb# cd /home/nvidia/ root@nvidia:/home/nvidia# ./LINUX\_LXTHREADSX86\_DrivePxApp.elf [you should see “shell\>EasyCan: Received configuration [OK].” from aurix shell]

Step 4.1 : Each time you changed EasyCanConfigFile.conf file, you should reset aurix afterward

## Shell\> aurixreset

Step 5: Enter CTRL-C to stop DrivePxApp and enter the following command to start DriveWorks canbus logger

root@nvidia:/home/nvidia/driveworks/bin# ./sample\_canbus\_logger --driver=can.aurix --params=ip=10.42.0.146,bus=a
