Hi @areusch, Thank you for your reply again.I have already sucessfully run the demo in your repository few days ago.I deleted several lines in this file and finally connected my board,though the runtime improvement of autotuned result wasn't so appealing compared with your 47%.Anyway,thank you so much for your generous help. Mike
