Unless I'm horribly wrong, the power up mode check is not done correctly in this port.
The following patch is only for trial purposes (as this is a code_gen port).
Code: [Select]

ping @koshy

Test build attached. Behavior should be the usual short press on power button or play button, start in playback mode. Long press on power button, start in rec mode.

Confirmed, that's what it does.

Koshy had a little ELPH which wasn't white as snow but everywhere that Koshy went the ELPH was sure to go. (actually an SD, but that detail ruins the rhyme...)
