Assistance Required for Configuring LIN over UART (Master/Slave Mode) on S32G3-VNP-RDB3

P_lavanya18 — Fri, 27 Jun 2025 17:28:45 GMT

We are currently working on enabling and testing LIN communication over UART on the S32G-VNP-RDB3 board running BSP . Our goal is to configure the board as a LIN slave /Master and verify communication using CANalyzer as the LIN master/Slave.

From the Linux user space, we have identified the following LIN-related UART devices:

FLEX_LIN: /dev/ttyLF2
LLCE_LIN: /dev/ttyLF3, /dev/ttyLF4, /dev/ttyLF5, /dev/ttyLF6

We are able to send data from the board to CANalyzer, but CANalyzer reports errors such as:

Invalid Header
Slow Response
Receive Error

Hi @P_lavanya18

Thanks for your post.

Could you please provide how are you doing the configuration to set the transmission?

Which BSP version are you using?
