12 years ago --- Quote Start --- Hi, does this kind of behaviour also happen if you try to debug helloworld or something like that? Does this happen after the first download after power up or only if you downloaded your code several times? --- Quote End --- Thank you, it happens also with very simple codes: I reduced many times my code to the bare minimal to understand if it was my fault. Usually I a simple hello world works but when I add simple things as delay routine it doesn't work anymore (it compiles and loads without errors but it doesn't print "Hello world" and even the reset KEY on the board doesn't work so I must stop from the IDE). Generally the problem comes when downloading many times, if I use a working code. I found a similar problem on alteraforum but the guy said he solved the problem changing the clock from 50MHz to 100MHz...I tried 24,50,27,108 MHz with a PLL and I'm shure it is not a clock issue. I must say that my NIOSII IDE is inherently instable, in fact many times it crashes...I tried reinstalling but nothing.
