Hello,

 NXP recommends do not use just SOC reset (OS restart), but - to implement total system POR instead,

via external circuit. For more details please create request (ticket).

Hi Yuri Muhin,

i.MX6DL LPDDR2 suspend / resume issue with Linux kernel 4.1.15  my problem is similar to this link.

Is there any solution for this like in 3.0.35 it is working https://community.nxp.com/docs/DOC-94922 . similarly can we get any patches or how we can check whether LPDDR2 is in self refresh mode or not.

Thanks in advance.
