Hardware and software tools: NIOS II IDE 10.1 ("Legacy") Quartus II 10.1 Device:Arria II GX - EP2AGX260FF35I5N I am using software tools and hardware as described and a custom board.When i am trying to debug through NIOS II 10.1 IDE ("Legacy") ,the simplest debug there is -Hello World ("Hello from NIOS II),i get connection message in the console and i see that USB Blaster is connected (Blue LED is on)- (i am using jtag uart),but i never get the message "Hello from NIOS II" in the console.If i try to program another simple program such as blinking LEDs it doesn't run/debug either.The problem is probably not in the board ,because at my work colleague's computer he is able to run/debug this simple programs without any problems.

The same problem is described in topic : t=26738 but i haven't quite got what exactly the user do,i can't PM him yet.Any ideas to resolve this issue would be welcome ( Or clarification of the topic mentioned )

Check these: - make sure you configured the fpga before starting Nios debugger - if you don't have a permanent Mios licence you must keep the USB blaster connected (don't close the warning window when fpga configuration ends) - check project and debugger properties: stdout must be set to redirect to jtag_uart module - in debugger properties the download and reset mode must be set to "Download program in RAM" and not to "Attach to existing program on target", nor "Reset target and execute..." - verify that when you start debug the code is actually downloaded: there should be a message in the console: download xxx kB... verify ...

well here are the messages: Build message: **** Build of configuration Debug for project hello_world_after_license **** make -s all includes Compiling hello_world.c... ../hello_world.c: In function `main': ../hello_world.c:21: warning: unused variable `g' Linking hello_world_after_license.elf...

Check debug target properties.

what should i check in debug target properties.what are the proper settings (your settings)?

Dear cris72
My fpga is EP3C120f484 and EPCS64.using the nios 9.0 and quartus 9.0
Now I am meeting some problems with nios debug.
the problem is in the nios debug window,the console print,here is my information:
Nios ii download output: Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

how is the problem solved,as I follow the ways with the website,it doesnot work!
