CAN Bus on Drive PX2 could not receive message from Host PC's PCAN

I tried to connect Drive PX2 CAN bus with my host PC PCAN. I could send message from PX2 and my host PC successfully received it. However, when I send CAN message from my host PC, the PX2 did not receive at all. Both CAN0 (Tegra A, using Can-5 cable) and CAN1 (Tegra B, using Can-6 cable) behave the same. To test, I used can-utils CANDUMP for receiving and CANSEND to send the message. I also set the ip link can0 and can1 up prior to using the CAN bus.

Here are the devices’ details by executing command

ip -details -statistics link show can0

Drive PX2 CAN bus could not receive any messages from host PC PCAN. How could I fix this problem?

Dear erickit,

Could you please refer to below steps for you topic?

$ sudo apt-get install can-utils

Step 1. Connected PCAN to can-5 port.(can-5 -> can0 on Tegra A)

Step 2. Enable can0 on Tegra A.
$sudo ip link set can0 type can bitrate 500000
$sudo ip link set can0 up

Step3. Run candump
$sudo candump can0

Step4. To cross check this , can you Just connect Peak CAN to CAN 5 on the harness (with proper termination) and Transmit message id 0x140 from PCAN.
