K61 FLEXCAN has no DMA support

[benjaminschroed]

I've been looking at the Kinetis K series processors, and it appears the CAN interface (FLEXCAN) has no DMA support, only interrupt.  Is this correct, or is there a workaround to be able to utilize DMA, specifically for Rx?

Thanks.

Hi,

Yes, you are correct. For Kinetis K61, FlexCAN is not a DMA request source and there has no way to use like that.

Thank you for the confirmation.
