Hi All.....
I am New to this Forum....
I have a small doubt regarding FlexRay Message...
What if the Message from Host is more than 254 bytes in FlexRay Frame...?(A maximum of 254 Bytes is allowed in FlexRay...There is no description of Overload Frame)
Thanks

hi Madhav,
This kind of situation can arise in flexray communication, specially while downloading s/w through flexray.
This is handled by transport layer s/w. And Transport layer messages are sent in dynamic segment.
The job of transport layer s.w is to divide the payload data >254 bytes in to smaller sizes. The max.
size of payload data in dynamic segment is a configurable parameter but again max, can be 254 bytes
only. Then this payload data is wrapped in a FlexRay TL frame ( which has slightly different format , header
and trailer segment is same) is sent. Remaining payload data is then sent in a separate TL frame in same/
next communication cycle depending on your network design.
Thanks
