RAM ECC and FCCU

Hi,

 

I'm working on FCCU for MPC5777C microcontroller and I'm trying to generate correctable/uncorrectable fault on RAM. In order to do this, I've followed the code present in this example:

 

Example_MPC5777C-1b+2b_RAM_ECC_error_injection-v0_2-GHS614

 

This code injects 1b/2b ECC errors on the RAM memory by the EIM peripheral and I see the results of the errors in the ERM peripheral but I don't see the signaling toward the FCCU. According to my understanding, I expect that fault number 45 or 46 should be latched in the  FCCU_NCF_S1 register because the same are enabled in the

FCCU_NCF_E1 register.

I have read on this forum another couple of questions about this point but I didn't find a solution or a hint. 

Is there someone that can help me understanding better this situation ?

Thanks in advance.
