When we debug the AM1802,the power sequence is 1.2V->1.8v->3.3V.When the 1.2V power up,we can test a 1.3V on 3.3V power pin. We disconnect the 3.3V power,the 1.3V still
exist.Remove all the outside devices except the DDR,the 1.3V still on the pin.
The field team has escalated this issue internally and we are looking at it.
Can you confirm that following
1) When you say you disconnect 3.3V , can you elaborate what you meant by this, did you remove discrete power ic that sources 3.3V?
2) Are you suspecting the AM1802 driving a 1.3V on the 3.3V supply?
3) When you say you removed all components , can you reconfirm that the only thing remaining on the board was the AM1802 and DDR memory?
4) Do you see a 1.3V on the 3.3V power pins only , or do you also see any voltage level on the 1.8V supply also?
