I recently met a problem about Lin communication,the version I use is S32DS_ARM_Win32_v2.2,and the lin component I use is lin,not lin stack，the lin is master，the LPUART is LPUART1,when I init the lin by LIN_DRV_Init and LIN_DRV_InstallCallback,The interrupt function LIN_LPUART1_RxTx_IRQHandler is immediately entered，The program enters the if statement as shown below, I don't know what happened, and I don't know how to fix it，someone can help me ,thank you very much.Note: I used freeRTOS.

Hi,

have you also configured LPUART pins properly and have connected LIN transceiver that is active?
