Dear NXP,

HW platform : imx8mplus 

SW version : 5.10.9-1.0.0

I connect can1 pin Hi to can2 pin Hi ,and can1 pin Low connect  can2 pin Low. I will use command as follows:

ifconfig can0 down
ip link set can0 type can loopback off
ip link set can0 type can bitrate 1000000 triple-sampling on

ifconfig can1 down
ip link set can1 type can loopback off
ip link set can1 type can bitrate 1000000 triple-sampling on

candump can1&

cansend can0 111#1122334455667788

Test result: 

write: Network is down
[1]+ Done(1) candump can1

 

Expect result:

111 [8] 11 22 33 44 55 66 77 88

 

Is there a mistake for running command ?

How to run command to test ?
