SPC58xG : FCCU error CPU 0 lockstep disable

Hi

I try to apply the safety guide on the SPC58xG

The FCCU is a main part to check the error on the SPCx58, but I have several problems.

1) FCCU Status error.

The status register has this value (after clearing, and read flowing in x0A mode)

FCCU_RF_S0 = 0x00040000

FCCU_RF_S1 = 0x00000000

FCCU_RF_S2 = 0x00200000

FCCU_RF_S3 = 0x00078000

The FCCU_RF_S2 error corresponds to channel 85

In RM0391, table 17 , it Lockstep CPU0 Disable 

When a Lauterbach is connected, this may be normal

But, when emulator is removed, there is the same error in my log file.

Why the CPU0 is not in lockstep mode ?

2) FCCU programmation

When a Lauterbach is connected, the FCCU change normally from NORMAL to CONFIG

The OPS bit, has state '1' pending , changes to '3' successful

But the same program, Lauterbach disconnect

The OPS bit, has state '1' pending , changes to '2' abort.

Why It's not possible to program FCCU ?

Regards
