We had finished test "mem-mode" on iMX28-EVK.

will wake up to using "PSWITCH" button on Mem-mode.


I have  some question.


1. How to check "Mem-mode" or "Power-Off" status??

- because iMX28 is RESET/ is Low status in Mem-mode.

- Can you tell me,  still using GPIO config on Mem-mode.


2.We using "PSWITCH" at wake-up source and Power On/Off source.

In IMX28EVK, long push PSWITCH for Power off. still working 32.768KHz sleep clock.

in case is more 12mA to Mem-mode.


root@freescale ~$

root@freescale ~$ release pswitch to power down

pswitch power down


is this normal case??


please help to me!!!
