when running the demonstrations for the tpad i run into problems such as node "c0" is missing source file. I was wondering if anyone can help me better understand how to run the tpad demonstrations or even displaying text on the 8" LCD it would really help me out.
I don't know about tpad. But the error you got is apparently related to the pll where node "c0" is the pll output. I came across a similar error when the pll used had the "altpll" name in sopc. Just change the name a bit (by adding one or two characters) and recompile.Hope this fixed your problem.
