On Board JTAG Debug failed in RiscFree IDE NIOS V Cyclone 10LP

Strange issue with JTAG debug connection with RiscFree IDE

Basics:

Board: Intel® Cyclone® 10 LP Evaluation Kit

Quartus 23.1.1

RiscFree™ IDE for Intel FPGAs v23.4.1, 3rd Nov 2023

Host system: Windows 11

The application is a simple NIOS V hello world. I am able to program the .sof file over the boards Altera USB-Blaster II. Debugging the application in RiscFree IDE result in an error "Selected debug probe is not available for debug session"

 

I have the MAX 10 10M08 Evaluation kit, which required an external JTAG to program the board. I used the EthernetBlaster II to program this board with a similar NIOS V hello world program without issue. I switched to use EthernetBlaster II on the Cyclone® 10 LP Evaluation Kit and I was able to debug. The response was a little slow, but it worked.

What is the issue with the on-board USB Blaster II not working?

    Hi


    Could you try lowering the usb blaster operating frequency to 16Mhz?

    If not then could you try lowering to 8Mhz and 4 Mhz.

    If it still could not work, please try using the RiscFree IDE from 23.1 instead of 23.4.

    @JingyangTeh_Altera

    Thanks for the suggestion. I lowered the frequency to 6, 4 , 2 , and 1, and the results were the same. If this is a RiscFree IDE version compatibility issue, I am not too worried about it since this is an older board. I have the EthernetBlaster II working, which is fine for my needs.

    Hi


    There is a compatibility issue where some users have some issue with debugging.

    This have been fixed in the latest Quartus 24.3 pro and for Standard you will need to wait for 24.1.

    You would need to regenerate your project in the latest Quartus version.

      Thank you for the follow up. As stated before, the external JTAG tool is working ok as a workaround. When Standard/Lite 24.1 is released, I will retest. Hopefully, the 24.1 fixes the connection issue and the MegaWizard issue as well.
