Last night I tried the ONOFF Button on the iMX6. The docs show a pin for an ONOFF button that is supposed to generate an interrupt which can be used to do a graceful shutdown of the system. The wandboard carrier board does not have a button for this, but it IS on the EDM connector, it just goes to a testpoint on the carrier.
I wanted to see if CSOS automatically supported this, so I hooked up a button in accordance with the schematic in the iMX6 docs, fired up the wandboard, pushed the button and NOTHING. It didn't do a thing. The docs also say that if you hold the button for 5 seconds or more it will do a hard power shutdown, no interrupt generated. So I tried it, again nothing. I checked and the appropriate voltage was getting to the testpoint, but nothing was happening. So either the wandboard docs are wrong and it really isn't connected to the testpoint shown in the schematics, or the processor is setup in some mode that ignores the ONOFF button. BTW I'm running F19-R2. I just wanted to see if this worked "out of the box", if yes I was going to add a few things on CSP1 to support this. But since it doesn't work out of the box I'm going to ignore it.
