Hi ,


I have an NXP S32K142 EVB board. I had a code which works fine In FD mode with 64 bytes message configuration.

When I tried to configure the message buffer to 8 bytes or less than 64 bytes I couldn't see transmit signal in oscilloscope.

The change I made is configuring the FDCTRL.MBDSR0 = 00 to make message buffer as 8byte size. Is there any thing more to update to configure for 8 byte message buffer.
