Congragulations I am glad you made it work and thank you for taking time to write an update about the progress you had.
Your other thread doesn't seem to have any useful suggestion other than redo everything all together.
Unfourtunately for me I can't switch to Ubunru or any other Linux type OS because I use other software in Windows and transporting all of them to Linux is just a big pain. I had to add a microconroller to my design just because I couldn't make NIOS working.
I guess I will not be using NIOS for a while. I wonder how Xilinx doing in Windows 10 :D
