We are using I.MX280 based EVT board. I have issues with the Suspend/Resume cycle for power saving. On EVT, the I.MX280 processor fails to resume from Suspend state on external events. The same issue is not reproducible on EVK that uses I.MX287 processor. Rest of the H/W and S/W is similar between EVK and EVT boards.
It seems that there is some difference in the clock domain between I.MX20 and I.MX27. I have gone through the Freescale website and google but didn’t find any useful information. It will be much help if anyone of you share some light on this?
