Hi,
We are doing a continuous environmental test for all the interfaces available in our custom board. Each interface tests are sequential and each iteration will take around 1.5 mins to complete testing all the interfaces in the custom board. And we are using two CAN interfaces in our custom board and we do loopback both the ports for environmental testing. And we can transmit and receive messages on both ports. We set the bitrate and enable the CAN ports by using these commands.
#ip link set can0 type can bitrate 1000000 # set bit rate
#ip link set can0 up # set can0 up
#ip link set can1 type can bitrate 1000000 # set bit rate
#ip link set can1 up # set can1 up
When we use the above command, we are getting the timeout message like below for each iteration (Log from Syslog). Why we are getting a timeout message? Whether the frequent timeout error will cause any problem if the system runs for more than 24 hours.
