DE1 SoC hangs when programmed

Hi!

I have made a small program to make a led flicker and programmed the FPGA with it. Everything went fine. However I have another project which I used to build in a previous version of quartus II and program it on an older cyclone II FPGA. I build this same project with the newer quartus II version 17.1 with no errors. However, when I try to program the cyclone V the following happens: the process starts properly, reaches 86% and then fails. After that I have to power off and on the FPGA so that it works again.

Any idea would be appreciated. Thank you.

    Is the project targeting the correct device on your board? Did you adjust the pin assignments in the Pin Planner?

    Yes, sure! Actually I am not that beginner. I have worked quite a lot with FPGAs.

    It used to give me a warning saying that the write logic was disabled. I rewrote my ram file and the warning dissapeared. I have also a warning stating the following:

    Warning (332060): Node: counter2 was determined to be a clock but was found without an associated clock assignment.

    Info (13166): Register \process_1:cnt[0] is being clocked by counter2

    Anyway, the project used to work on older software/hardware versions so I do not believe that the problem is related to code.

    I got it to work fixing the warning about the ram. However it only works under restricted parameter's values, so there is still something missing...

    Thanks.
