Hiya,

How can my legato app determine if the processor has booted from been ‘reset’ (i.e. power cycle or reset) or has woken up from ULPM?

The boot reason API only appears to provide info for ULPM wakeup.

ciao, Dave

le\_info\_GetResetInformation() can let you know more about reset cause.

You can test this with “cm info”.

Cool, thanks.

I’ll look into it and see if it does what I need.
