Hi,
Well as I was trying to get the logs that @inabirushkin suggested in his last post I rebooted the board and to my utter surprise everything is working fine now !!! I can profile using the System Profiler v4.
I cannot explain what happened … I cannot reproduce th error anymore. By the way I have no “/tmp/target_nvlog.log” file on my board(I put the config file at the correct location). If the error appears once again I will report it here.
Thank you all for the support and for the help
