Hi,
VDDS_RTC of AM3359 is getting powered from VRTC(pin29)of PMIC. The board was working for some time but suddenly PMIC became non functioning. I took the measurement on that pin it is about 1.4V instead of 1.8V.
When I gave 1.8V externally to that pin, It is back to working. So I have following queries:
1. I am aware there were some issue with AM3359 silicon version 1.xx. It was told that it will be resolved silicon rev2.0. Is silicon rev2.0 is released? if so when it was released?
2. what is the best to solve this problem? I am also aware that external LDO is suggested. my queries is how it should be done? do we have to short external LDO output and VRTC output of PMIC together?
please help me clear this doubts.
Regards,
Ibram
