S32K312 LIN LPUART_LIN_IP_RX_OVERRUN_ERROR

[jichengyou]

Hello everyone:

I tried to use S23K312 for Ip Lin debugging with Baby Lin II.

Whether I use slave mode or master mode, I get LPUART_LIN_IP_RX_OVERRUN_ERROR, and even LPUART_LIN_IP_FRAME_ERROR and LPUART_LIN_IP_PID_ERROR.

I also tried to change the bit rate, such as 19200 or 9600, but nothing seemed to work.

Attached are screenshots of the engineering and debugging I used.

Please help me confirm what my problem is.

Also, please help me explain what each error in the enum type Lpuart_Lin_Ip_EventIdType means, as I feel the remarks about it are unclear.

Hello @jichengyou,

Based on our discussion in a support ticket, the last problem with LPUART_LIN_IP_STATUS_TX_BUSY after SYNC has been send can be caused by an issue in the HW of the tranceiver, because it occurs after Power-on reset.

Regards,

Daniel
