Error while uploading: missing 'recipe.cpp.o.pattern' config

Hi there, I think that I found the problem.

Somehow I was still using in the programmer option “Arduino ISP”

I never even know you had to go there.

I did select instead USBTinyISP and then was able to upload without any more error message

and yes the led was finally blinking

Thanks you for your help.

Very happy Daduhaime.
