I have searched for and have tried many suggestions but nothing seems to solve the
problem. I am missing something or make the same mistake over and over. Please help.
I just successfully completed a ATSAME54P20A -selection with MDK 5.29 after installing Atmel::SAME54_DFP 1.1.134.

Next I generated a project and the build was successful:

Thank you very much. I uninstalled Keil uVision 5, removed everything Keil from my hard disk, Installed uVision 5 again, created new project per your reply and WALA SUCCESS FINALLY. I assume I made some blunder with previous installation followed with more blunders. Again thanks.
