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

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
