CAN BUSOFF recovery function listed below, you need to rebuild the CANFD driver after you add it to the CANFD lib.
How to rebuild CANFD lib: 
1.        Open CMD，cd C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\canfd 
2.        Call “C:\ti\mmwave_sdk_03_05_00_04\packages\scripts\windows\setenv.bat”  with enter 
3.        Call ”C:\ti\mmwave_sdk_03_05_00_04\packages\scripts\windows\checkenv.bat”   with enter
4.        gmake all   with enter
 
  
----Add function CANFD_BusOffRecovery  in canfd.c 
int32_t  CANFD_BusOffRecovery(CANFD_Handle handle,  int32_t* errCode) 
{ 
   CANFD_DriverMCB*                ptrCanFdMCB; 
   uint32_t                        baseAddr; 
    int32_t                         retVal = 0; 
     
   ptrCanFdMCB = (CANFD_DriverMCB*)handle; 
   if ((ptrCanFdMCB == NULL) ) 
   { 
       *errCode = CANFD_EINVAL; 
       retVal = MINUS_ONE; 
       
   } 
   
   baseAddr = ptrCanFdMCB->hwCfg.regBaseAddress; 
   /*Check if the busoff status and also the Error counter*/ 
   
   /* Put MCAN in opertional mode */ 
   MCAN_setOpMode(baseAddr, CANFD_MCANOperationMode_NORMAL); 
 
   /* Wait while MCAN is not in operational mode. TODO add timeout */ 
   do 
   { 
   } while (MCAN_getOpMode(baseAddr) != CANFD_MCANOperationMode_NORMAL); 
   
   return retVal; 
} 
	
	 
----Add function in main.c 
static void MCANAppErrStatusCallback(CANFD_Handle handle, CANFD_Reason reason, CANFD_ErrStatusResp* errStatusResp) 
{ 
   int32_t                 errCode; 
   gErrStatusInt++; 
   gErrorReason = reason; 
 
	 
		// check the callback reason
		// you can also adding CANFD_transmitDataCancel here to avoid TX to cause busoff
		
		   /*Try Busoff recovery*/ 
		   CANFD_BusOffRecovery(handle, &errCode); 
		       
		   return; 
		}
