Hi,
I need strong advice regarding FlexCAN configuration.It seems I have no problem with transmission, but I have huge problems with reception.I am using S32K144 evaluation board.It looks like it receives only one Message Buffer at one time. What I mean is we have to configure MB for a specific ID and after the reception of that Message we can configure other MB with different ID i.e kind of cyclic reception.
My use case is the following:
1. I have 8 ID's for reception and for that MB0 - MB7 are used for reception . Idea is to catch ALL 8 incoming frames(ID type is standard )
2. RXFIFO should NOT be used.
Questions:
1. Is it possible to configure FlexCAN to achieve this behavior?
Hi,
Per my understanding this SDK driver allows using one TX and one RX message buffer at a time. Thus I think your config cannot be done with this driver.
I can suggest to configure the FlexCAN directly touching module registers. You can refer to this demo code; https://community.nxp.com/thread/433482; modify it to use more MBs for RX function.

Thanks petr,
I didn't find anything like touching module in datasheet please help how to configure and use this module for Flex CAN.
The link you shared for demo code is not opening,it shows the following error.
Thanks and BR,
