What is JTAG Debug Level 3 for Nios II?

Hello everyone, I would like to trace program execution on the Nios II. One way - to buy Lauterbach - not interesting. Second way - use SignalTap II and .objdump file - pretty well, but still. And n...

Hi, First of all, you can choose the debug level in the Eclipse to meet the settings you put in the Qsys design so you can use the features in the NIOS Debug please review the shared documents before. Here you can find good references for tracing and debugging https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/wp/wp-01198-fpga-software-debug-soc.pdf https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/nios2/edh_ed51003.pdf https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an543.pdf http://www2.lauterbach.com/pdf/debugger_nios.pdf Regards,

    Dear Embedded_guy,

    About debug level in Eclipse. I didn't find any document which describes this little setting. Anyway, by turning on the same level of debug in project settings I now can profile my code, but still no trace is still avaliable from Eclipse, or I just didn't find how to turn it on yet.

    -The first link is about SoC systems with ARM, so it doesn't helpful for me since i'm about Nios

    -The second link is better, but, unfortunately, it is about Nios II, not Nios II gen2, moreover, it is dated as December 2009... Are you sure that everythinf is the same? (spoiler - no)

    -The third link describes OFFCHIP trace, while my question is about ONCHIP trace

    -The fourth link is about software for using of the third's link OFFCHIP tracing

    Unfortunately your answers doesn't help at all, so I don't know if it is me asking too bad or support-team don't know what the right answer is.
