[edenli]

Hi Guys,

I use the MPC5744P CAN block build the module,but there isn't any data being sent out,

i check the reason ,and i try the method by CAN Configuration issue on MPC5744P ,but still can not solve it

The CAN Engine Clock Soure is 40MHz by oscillator.

The attachment is my modle.

Hi edenli

What type of board are you using? The big one ( Development board) or the small one ( credit card format - Dev kit ) ?

Best regards,

Daniel

Hi Daniel,

My board is MPC57XXXMB and MPC5744P-257DS.

I can't check right now - but i think you need to use the v1.1.0 (https://nxp.flexnetoperations.com/control/frse/download?agree=Accept&element=6107521 ) of the toolbox for MPC574xP. The 2.0.0 supports only the newer parts. That might explain why is not working.

Best regards,

Daniel
