Hi
I am using MPC5744P,
The execution gets halts in while loop, once i try to enter into configuration state.
The execution will enters into aborted state, we are clearing the FCCU.NCFSx flag before entering into configuration state.
And I am not debugging it, since because of watchdog timer starts once i try to enter into config state.
The Code using:
/* Unlock configuration */
FCCU.TRANS_LOCK.B.TRANSKEY = 0xBC;
/* provide Config state key */
FCCU.CTRLK.R = 0x913756AF;
/* enter config state - OP1 */
Clear_Flags(); /*Clear NCFSx falg*/
FCCU.CTRL.R = 0x1;
/* Verify if state change was sucessful */
while (FCCU.CTRL.B.OPS != 0x3)test=FCCU.CTRL.B.OPS;
To Clear the NCFSx using below code:
FCCU.NCFK.R = 0xAB3498FE;
FCCU.NCF_S[0].R = 0xFFFFFFFF; // read FCCU.NCF_S0 register
/* Verify if state change was successful */
while (FCCU.CTRL.B.OPS != 0x3); //Operation status successful
/* NCFS_1 register clear */
FCCU.NCFK.R = 0xAB3498FE; //Non-critical fault key = AB34_98FEh
FCCU.NCF_S[1].R = 0xFFFFFFFF; // clear FCCU.NCF_S1 register
/* Verify if state change was successful */
while (FCCU.CTRL.B.OPS != 0x3); //Operation status successful
/* NCFS_2 register clear */
FCCU.NCFK.R = 0xAB3498FE; //Non-critical fault key = AB34_98FEh
FCCU.NCF_S[2].R = 0xFFFFFFFF; // clear FCCU.NCF_S2 register
/* Verify if state change was sucessful */
while (FCCU.CTRL.B.OPS != 0x3); //Operation status succesfull
Peter Vlna,
Is there any thing i am missing?
is there any other way of doing it?
