Hello team,
Can you please explain the details(especially error condition) of MPC5748G FCCU faults below?
1. NCF[18] / MEMU_0 / System RAM error overflow (all or'ed)
2. NCF[20] / MEMU_0 / Peripheral RAM uncorrectable ECC error (what's the Peripheral RAM?)
3. NCF[25] / PRAM_0 / System PRAM Controller_0 ahb alarm
4. NCF[41] / DMC PRAM1 / DMC PRAM1 FCCU ALARM
5. NCF[43] : PRAM_0 / System PRAM Controller_0 RAM alarm
There are two DMC PRAMx FCCU alarm faults - PRAM1 and PRAM2. Why isn't the DMC PRAM0 FCCU alarm fault?
Best regards,
James

Hello,
1. NCF[18] / MEMU_0 / System RAM error overflow (all or'ed)

For example CAN buffers.
3. NCF[25] / PRAM_0 / System PRAM Controller_0 ahb alarm
It signals that there was and uncorrectable RAM error on masters AHB.
4. NCF[41] / DMC PRAM1 / DMC PRAM1 FCCU ALARM
Alarm signal from DSMC to FCCU
5. NCF[43] : PRAM_0 / System PRAM Controller_0 RAM alarm
There are two DMC PRAMx FCCU alarm faults - PRAM1 and PRAM2. Why isn't the DMC PRAM0 FCCU alarm fault?
Hmm, hard to answer. I expect it corresponds to 0 and 1. But this would be question for documentation/ application team. You can rise a ticket at NXP.com or get in touch with application engineer.
Best regards,
