annotate Discovery/Src/externLogbookFlash.c @ 466:538eb1c976e9 Improve_Logtansfer
Removed invalidate header function because it is no lonnger needed
Added new function allowing to read the profile length from sample data
Added function which validates the wrap around detection
In older versions a corruption of the sample index could occure reseting the sample index to its start. For some code sections this looks like a wrap around of the sample ring. To avoid problems a function to check this by reading the last bytes of the sample ring (should be != 0xff if used) has been added
