Hello Community,
I would like to make QM grade PMIC(VR5510) to NORMAL_FS.
I already succeeded to make ASIL-D grade PMIC to NORAL_FS by following VR5510 reference manual.
But I don't know how to make NORMAL FS on QM grade VR5510.
It still stayed in INIT-FS even though set same as ASIL-D grade VR5510.
Thanks,
Harry
Solved! Go to Solution.
For QM version VR5510 , it can not enter Normal_FS state as FS0B can not released on QM version device.
So you don't know how to enter into normal mode, right?
I could made normal state on VR5510 ASIL-D grade.
But it wan not changed INIT_FS state with same way on QM grade VR5510.
Can you explain more for --- it wan not changed INIT_FS state with same way on QM grade VR5510?
For the ASIL-D grade VR5510, I could make NORMAL_FS by following below step:
1. Write goot watchdig
2. Run ABIST2
3. Make FLT_ERR_CNT=0
4. Release FS0B
5. Then FSM_STATES in FS_STATES register changed to NORMAL_FS.
But the QM-grade VR5510 doesn't support ABIST2 and FS0B.
So, I just write goot watchdog to exit from INIT_FS.
When I did above 1~4 steps on QM-grade VR5510, there wass no state change.
Thanks,
Harry
QM version means operate as non-safety part.
Yes, correct.
So you question is: how to do for enter into Normal mode by QM version, right?
Yes, when I read the FS_STATE register, I want to get NORMAL_FS state on QM VR5510.
For QM version VR5510 , it can not enter Normal_FS state as FS0B can not released on QM version device.
Thanks for clarification.
