Hi Nordic,
I'm looking at the PM_EVT_FLASH_GARBAGE_COLLECTED event in SDK14.2 and have noticed that it is generated even if garbage collection fails. Currently no error code is returned with the event so, there is no way to tell whether GC succeeded or failed without using other information
For example, from another FDS_evt_handler, I can see that GC is timing out but PM_EVT_FLASH_GARBAGE_COLLECTED is generated.
Also since it takes so long, I think a function in the FDS module to tell whether garbage collection is in progress or not could be quite useful.
