Hi all,

 

I am currently configuring MCAN0 for MPC5777C and testing it on MPC5777C Evaluation Board and using Vector VN1640A for Testing.

 

i set SIU_PCR[83] and SIU_PCR[133] to alternate functionality 2

i disconnected J37 J38 and J35 jumpers

i connected PL3 to J35 Tx

      and       PL4 to J35 Rx

i connected my canoe to J6

 

i am unable to tx or rx anything 

Please Help!!

 

UPDATE :-  Q1. so i connected back the jumpers J35 and J37 J38 in 1-2 position and i connected my canoe to CAN2(J5) and MCAN0 is working but FlexCAN_A also uses the same CAN2(J5) for communication so how does the Evaluation board differentiate between both when they both are configured ??

 

Q2. How do i test MCAN_1 which jumpers do i have to change and/Or if i need to supply i/p to the tranciever which port pin on the EVB do i take it from (i tried PC8 and PC9, didnt work) and which SIU_PCR would i have to configure for the alternate functionality of the same??

UPDATE2 :- Nevermind i solved this one, for anyone else having same trouble move J37 & J38 to 2-3 position and connect Canoe to J6 to get MCAN_1 working

 

 

Q1 still remains though

Thank you in advance
