CAN FD 8Mbps not working

[yalamandadosaky]

Hi, I am using S32ds power pc v1.2 and MPC5748G EVB,I have successfully transmitted with CAN FD 1Mbps, 4Mbps but 8Mbps is not working. I have tried different baud rate settings

My baud rate settings are

.bitrate_cbt =

{

.propseg = 0,

.phaseseg1 = 1,

.phaseseg2 = 1,

.preDivider= 0,

.rJumbpwidth = 1

}

I have enabled TDC and offset value changed from 1 to 10 but still it didn't worked.

Can anyone help me to is there any problem with these settings or give me an idea how to resolve it.

Hi PetrS‌, Through Component inspector(processor Expert) I am unable to change the PE clock frequency to more than 40Mhz.

Is there any other way to select the more than 40Mhz clock frequency.

Thanks

checking a MPC5748G DS/RM I see max FlexCAN PEclock could be 40Mhz. Thus max bitrate is 5Mhz.
