NXP S32K1XX busoff related issue

[Tomzhang1]

   I met a question,  when  S32K118  ECU enter busoff interrupt , I want to clear mesage buffer in flexcan.

I tried some function , such as FLEXCAN_DRV_AbortTransfer and FLEXCAN_ClearRAM. Such action will cause reset, and busoff cannot go on. If I don't clear the buffer. After bus off recover, flexcan will send unintended frame which  influence  judgement of busoff recovery time.

  So could you provide a useful interface function which can clear message buffer.

  Thank you very much!

Hi@Tomzhang1

I have already repplied to you another of your same topic.

you can use FLEXCAN_DRV_Deinit,then -> FLEXCAN_DRV_Init，the bus off count is incremented by one,and the time base for fast and slow recovery is adjusted according to the bus off count.
