Hello Daixiwen,
thank you for your answer.
If I don't close a window that appears, as you explained, I can download the ELF :)
I can run this, but it is weird because this project was working at my university on Altera software with all the licenses, but now, it is not working here.
It is an LCD controller, I am using: NIOS II, JTAG UART, EPCS flash controller, SDRAM, ALTPLL and LCD module (mine). The registers and memory seem to be well-configured :S Is it ok if it is compiling without doing the EDA Netlist Writer? I am a beginner and I am a bit lost with some stuff.
Thank you very much for your help!
