MKW36A FlexCan only 125k Baud

[lukas_berger]

Hello,

I am running the flexcan_interupt example program from the FRDM-KW36 Dev. Board on the MKW36A512VFP4 Controller. 

When I ran the example with a baud rate of 125k I can send and receive Messages with out any problems. But when I change the baud rate to 100k, 250k ,500k or 1000k I can't get the program to work. With these baud rates as sonn as there is traffic on the CAN bus the flexcan_callback function reports an error 5310. 

With the baud rate of 125k I can monitor the CAN messages with a Scope. But with all other baud rates the Scope can't decode the message.

Do I have to change some clock or bit timing settings to get the other baud rates to work?

What confuses me the most is that the flexcan_interupt example is configured with a baud rate of 1000k an it doesn't work.

Any help is highly appreciated.

Regards,

Lukas
