MPC5744P FCCU fault (NCF[56,57,58]) cannot be injected issue

[Zhongling_Lang]

Hi,

1.Now my customer test fault injection in FCCU module on mpc5744p and the NCF[56/57/58] cannot be injected, but in RM said that this three NCFs can be set and cleared.

2.This issue actually exist when I tested on MPC5744p devkit board(use the SDK code<fccu_fault_injection_mpc5744p> and sample code in our community). So why the RM information is inconsistent with our test results.

3.On the other hand, we test the fault injection on other MCU(mpc5746r,mpc5775e) and also have mismatch with RM information. may be some other information we should pay attention.

Hi,

You are right.

There is documentation ticket in place for quite some time. So the fix should be in near future.

Remove the fake fault injection capability for the NCF[56], NCF[57] and NCF[58] from the table 7-33. FCCU Non-Critical Faults Mapping in the chapter 7.12.3.1 Fault inputs.

regards,
Peter

Hi Peter,

Thanks for you reply, I will also update some fault injection mismatch with RM on MPC5746R and MPC57775E.
