Re: Multiple Eclipse installations - How to control which one?
Problem was for some reason suddenly solved... After uninstalling the "normal" Eclipse, the NiosII Eclipse still did not show the Templates. However after digging down into File -> New -> Others the NiosII Templates could be found. After this, the Templates are now also visible under the File -> New section. Something "hi-jacked" the view, and was restored by some coincident... Can't explain it, but considering this case closed! 😉 /Nikolay1.6KViews0likes0CommentsRe: Multiple Eclipse installations - How to control which one?
Hi. The question is not which one I want to use... Eclipse does support to have multiple versions installed: https://stackoverflow.com/questions/16764625/is-it-possible-to-have-multiple-eclipse-installs-on-one-computer The question is why Nios II Software Build Tools for Eclipse starts without the NiosII plugins like "NiosII Application and BSP for Template" even after the generic Eclipse was uninstalled?

It turned out to be that the FPGA clock source to the NiosV debug port was lower than the JTAG_CLOCK frequency.

Hi. With Quartus 22.1 Standard on Windows, I had the recommended Eclipse CDT 8.8.1 installed as described in https://www.intel.com/content/www/us/en/docs/programmable/683525/21-3/windows-installation.html It was working fine. Then I also installed a standard Eclipse release from https://www.eclipse.org/downloads/ Now both Quartus(Tools menu) and NiosII Command Shell launch the standard Eclipse (without NiosII support) instead of the CDT 8.8.1 version I placed under \22.1std\nios2sdk\bin\eclipse_nios2\ What mechanism controls which Eclipse version is launched? Can I control this? Can multiple Eclipse versions coexist on a Windows machine? /Nikolay1.7KViews0likes5CommentsRe: Design Space Explorer can't open .ip files
One user reported to me about similar error message. His root cause turned out to be a lot of "undeletable waste" in %TMP% directory. (Files without user permission) Changing the %TMP% to a different location with more space solved his problem. Question to Intel SW development team: Is there a file handle leak in the DSE?

Hi. Totally different example though, but same error on Windows server with Questa 21.3: Problem solved by changing Windows environment variable LongPathsEnabled to "1".

This works in QSys on Quartus 16. Is there a work-around or am I stuck using 16?
The workaround is to copy the following directory from 18.1 into same location in whatever newer release(20.1 and 21.1): \18.1\ip\altera\ip_compiler_for_pci_express Hopefully the directory will make it back into the 22.1 installation 😉3.2KViews0likes0CommentsRe: Error: s0: Error during execution of "{C:/intelfpga/20.1/quartus/../nios2eds/Nios II Command Shell.b
Hi Filip. This patch solved the problem on my computer: https://www.intel.com/content/www/us/en/support/programmable/articles/000088789.html It did however not solve it on another customer's computer, so I would be interested to hear your result... /Nikolay2.1KViews0likes1Comment
