Hi community： I'm using CANFD on stm32g431kbu6 board, but I find some issue that CANFD cant work normally with BRS ON，my config of CANFD show in the comments。Does anyone know about this？ Thanks

Because my slave CANFD device is working in sampling point at 75% of data phase, data baud is 5MHz， so I want to set at 75%, it seems work good now, I'll conduct pressure testing for a period of time.If this kind issues happen again, I'll try your a...

I find some issues in different config of FDCAN,my configs list below:PCLK of FDCAN is 160MHzData Prescaler：8Data Sync Jump Width: 1Data Time Seg1:2Data Time Seg2:1When I config like this, I saw that the TEC keep increasing until the CAN controller ...

Thanks for your reply，I will keep on troubleshooting this issue. And I wanna know if the FDCAN of Stm32G431KBU6 can automatically recovery from bus-off status to error-active state？if yes, should i set some register bits to enable this feature like C...

OK, and I find the reason, there is another CAN node with inconsistent data area sampling points （80%）in my CAN bus，my setting is 75%,so when it work together, CAN bus hang up
