Dear NXP engineers,
I just want to make sure this symptom is normal or abnormal thing.
MCU : NXP MPC5777C 3N45H
Compiler : WindRiver DIab 22.214.171.124
Operating system clock : 264Mhz
OS : ETAS RTAOS
I tested with on-line tset code(MPC5777C_on-line_bist_3N45H.c) at AN5288 "MPC5777C STCU Quick Start Guide"
This is test sequence
1. Core 1 is halted and reset.
2. Core 0 is running only
3. Execute run_online_bists()
4. FCCU Isr is invoked
I have been set to FCCU register, especially, 10th RCCU_0, 23rd PLL_0 are set.
5. FCCU detect RCCU_0, PLL_0 fault during on-line bist.
like below, Captured from T32 PowerView
I think FCCU check Core 0 and Core1, RCCU. So FCCU could detect fault even though It is not real fault.
Also I could see our system come back to normal operating mode after on-line bist is completed. Of course there is running reset due to STCU.
Do you think so? Or I should change configuration?
Please give me your feedback.
