Xavier jetson development kit CAN controller test

By sample do you mean the bitrate - ie change from 500K to 1M.
That would be
ip link set can0 type can bitrate 1000000
ip link set up can0

CAN “Sampling” is defined by 4 timing parameters. Go to a web site like … http://www.bittiming.can-wiki.info/ and put in “goal” bitrate and it will calculate a few combinations that will work.

Then set them in the driver using libSocketCan or the command line interface…

ip link set can0 type can help
Usage: ip link set DEVICE type can

Hello all ,
I have trying to connect the 2 can controllers in Nividea Xavier AGX with each other as the follwing git repo : GitHub - hmxf/can_xavier: CAN Bus Drive Script
but when I send candump can0 and send from can1 I got nothing .
also i try to connect the 2 controllers without transceivers
attached bellow the status of the 2 can controllers :

So could any one help please
