We are using 2x (high Speed CAN) and TJA1055T/3/1J(Low Speed CAN) in our design.


We are going a head with production. 

We have looped HS_CAN1, HS_CAN2 and LS_CAN at physical layer. as shown in attachment. 

Please let us know whether looping HS_CAN to LS_CAN is fine? 

If not please suggest if you have any method to test Low speed CAN.
