Does a FreeRTOS kernel extension exist that allows the EFM32 into enter into low power mode (EM2)?  The current demo says only EM1 is supported.  If no extension is available, is one being worked on? Thanks.

There has been some considerable work on this very thing.  I will find out the status and report back. Regards.

Apologies for the delay.  See here:

Thank you.
