LPUART_DRV_Init(INST_LPUART2, &lpuart2_State, &lpuart2_InitConfig0);//Initial UART2

but when the upper computer send the data to S32K144 ,the s32k144 could not enter into LPUART_DRV_IRQHandler?

You must use the LPUART_DRV_ReceiveData(uint32_t instance,uint8_t * rxBuff,uint32_t rxSize)and the IRQ can ener into.
