Hi all,

 

We have designed our custom board with i.MX538 PoP with LPDDR2. We are trying to reduce the device sleep current by setting the LPDDR2 RAM into self refresh mode during the power down mode. But we have encountered problem that the system cannot wake up after that. Anyone have experience the same problem?

 

Please advise.

 

Thanks.
