I want to set the security bit GPNVM for SAMV71 in code. First of all I looked here http://asf.atmel.com/docs/latest... but the efc.c does not exist in the atmel studio. Only efc.h exists. I tried to include efc.h file but I get lot of errors. Anyone has been able to set GPNVM but for SAMV71 through code then please let me know.
