Occasional ContributorNios-V .elf download failure
Hi Balerion,
When you are able to download the elf using the --go command, it is likely that your setup on the board is correct alreadyThere is an update by the way. I tried the command
*****************************************************************
"niosv-download.exe app.elf --go"-> Hello Nios V World!
*****************************************************************
And you saw this error when trying to connect with RiscFree
Initializing connection ...
Cannot set the JTAG frequency, continuing with auto adjust mode
Connected to target device with IDCODE 0x2e240dd using USB-Blaster-2 (1) via JTAG at 24.00MHz.

Press 'Q' to Quit.This could be your RiscFree's setting or your host system's setting not set correctly.
Likely Root Causes
GDB Server launched by risc free failes to connect IDE cannot detect the prompt (gdb) migh due to the followinga) Firewall/antivrus is blocking the local host port access
b) IDE times out before connection is established
c) There is a mismatch in how the debug config launches
Possible Fix
a) Temporarily disable antivirus / firewall
b) Try launch RiscFree as administrator
c) Increase debugger timeout (if IDE allows)
Please let me know the result after you try the step and provide screenshot if possible.Regards,
Boon Khai
