I am using TJA1145 for my project and partial networking.
my problem is that I do not understand exact wake procedure from BUS off status to Bus active.
In my case, I need to send 2 consecutive wake up code to wake up the CAN BUS.
below is wake up sequence.
1. CAN BUS oFF status
--> my ECU send Wake up pattern via CAN bus
2. CAN BUS level goes to 2.5V
--> My ECU send same wake up pattern as before.
3. CAN wake up.
4. CAN BUS goes to normal status.
I would like to know how I make CAN BUS waked up with only one time wake up signal transmission on the CAN.
