Hello,Actually, I have a project with an FPGA, I installed Quartus II 12.1 Subscription Edition without license from the original CD. I try to do my simple application and everything was good until the compilation was successful, but when I connect my board with a USB - blaster. I try to charge the file" .sof " I don't find it. What's the problem? Is it related to license or something like that? My board is cyclone V ref:5CSEMA5F31C6N and I choose 5CSEMA5F31C6 in QuartusII Is there a deiiference in the device? Please help me, I need to start my project There are some attachments to show u more details. Thanks.
The device type (N suffix) does not matter here. What DOES matter is you installed the subscription edition and did not provide a valid license file.You should install the FREE (Lite) version of Quartus (selection available here, by device family or by version): https://www.altera.com/downloads/download-center.html 12.1 is pretty old, unless you need to use such an old version going with the most recent (17.1) might be a better choice when starting from scratch.
