my project is slave ,the callback can enter lin38 ,which means it can receive 0x3c.but can not receive 0x3d, here are my project

void Lin_Init()
{
Lpuart_Lin_Ip_Init(INST_LIN2,&Lpuart_Lin_Ip_Sa_pHwConfigPB_0_BOARD_INITPERIPHERALS);
IntCtrl_Ip_InstallHandler(LPUART2_IRQn, LPUART2_LIN_IP_RxTx_IRQHandler, NULL_PTR);
IntCtrl_Ip_EnableIrq(LPUART2_IRQn);
}

Hi,

have you sent LIN header with Id 0x3D from master so slave can respond, i.e. callback called?
If RTD does not offer CurrentId, only CurrentPid, then compare with expected Pid value in callback. For Id =0x3D the Pid if 0x7D.
