Enabling Reset button/Power button functionality on Kingfisher + M3 Starter Kit

According to the schematic the power supply seems to be controlled from Kingfisher(M05). I think you can not control power from SW8.

Is there any switch/workaround to reset the kingfisher board ? Or would this be considered as a hardware limitation and no work around possible ? Although we would hope this is not the case.

>>Why do you need reset rather than SW6 on Kingfisher?

We want to evaluate suspend to RAM mode of hibernation. For this, we are expecting to keep the power ON for the board so that during hibernation the contents of RAM are not lost. Software control for reset is not present so we need a RESET functionality equivalent like provided by SW8.

Also we need kingfisher board for getting CAMERA interface CN29 access to M3 target.

SW6 erases the RAM contents so we are not able to use it.

Would you please let us know any workarounds, if possible, for this use case ?

Thanks in advance.

KF doesn't support Suspend to RAM(S2R).

In order to support S2R on SK+KF, it is necessary to redesign the power control schematics on KF.
(I have never heard of such a plan.)

We understood no support considered for S2R so far. Thanks, Gohda-san, Chetan-san.
