    Firstly, is your usb blaster working? Can check if the jtag connection is working at the Quartus II Programmer.

    Secondly, have you successfully run full compilation in Quartus and downloaded the .sof file into your board?

    Is your pins being assigned correctly especially you reset pin? The other thing you can check is the Nios II debug reset request. Is it connected to the jtag reset port?

    thanks forum_newbie for the answer..the pin already assigned correctly...but the problem still occur..where can i find the nios ii debug rest request because im really blur about that...and for your information i use nios II/e version because i dont have the license..is it this version of nios make the "elf process downloading failed" occur? and if i use nios II/f..is it the problem can solve?

    Hello Bittersweet,

    I wrote a large post about pitfalls I fell into when trying to get Nios/e operational.

    You might want to look at "Read/Write data to SDRAM on DE0 nano using NIOS ii"

    Best Regards,

    Johi.

    Which version of Quartus are you using? And can you provide me your design for me to take a look at it?
