LIN slave support for MPC563xM

Hi everybody,

 

 

I am developing a little LIN network with one master (LINAnlyzer by Vector Informatik) and one (or more) slave(s).

I need to develop slave node using mpc5634 Monaco, that contains native support and LIN fsm only for master node .

I also have a master node based on the same mcu (LIN TX/RX DMA controlled),

I am encountering a lot of problems, first of all I am not able to correctly receive an header if I do not trigger TX DMA channel connected to LIN_LTR register as first thing, i.e. if I sent an header I also receive correctly data hdr+response sent by LINAnlyzer(but it is an error, considering that slaves node simple receive header, handle it and, if required, sent a response on the LIN bus).

Has anyone worked on this before me?

 

 

Any suggestions would be very appreciated!!!

 

 

Thank you in advance,

 

 

Regards
