Why do I get "Ignored Assignment" warnings in the Fitter report?
I have a number of pins that are listed under Ignored Assignments that were once in my design and now are removed. I have no reference to them in the top HDL, there are no Location assignments to these pins in the Assignment Editor, and nothing in the QSF referring to these pins. How do I find where these location assignments are coming from? I am running Prime Lite 18.1.0 on Win10. Thanks, John.Solved2KViews0likes3CommentsRe: ALTPLL hangs on Ubuntu 18.04
I had this on U16.04. Happens on other IP as well. I got round it by dragging the megawizard window bottom right corner so that all the scroll bars disappear. Do it on the first window that pops up before selecting any options, Then it should work.2.2KViews0likes0CommentsWhy do I get this Synthesis error?
I am building a variant of a working project, using Quartus Prime Lite. It fails Analysis & Synthesis right at the end (97%). I have tried in V17.1.0 and 18.1, same error with both. It occurred after I modified an Avalon FIFO memory component in my qsys system. When I compare the sdc file from this project with my earlier successful project, only the project names (my_proj) are different. Any Ideas/workarounds? Thanks John.

Brilliant, that fixed it! Unchecking POF_ERROR makes it boot from 0x000000 and removes some of the functionality of the RSU in the App-image. This means you can't use the same image for Factory & App , if you want POF_ERROR-checking in the Factory image. Not a problem for me. Thanks Nooraini.1.4KViews0likes0CommentsRe: Remote re-configure a Cyclone IV in Application-mode?
"You can just trigger the reconfig input from the RSU IP if you want to fall back from App images into Factory image." - This is exactly what I want to do, but it doesn't seem to work, when it is running the App-image. When I write to ru_reconfig my hardware gets stuck trying to load an image from the EPCS16. As further info: I can see in signaltap that it is trying to load an image from 0x100421 (my App-image lives at 0x100000). Somehow the boot-address has been changed during re-config and as the MSM is now in mode 1, so I can't write new data into the RU_CSR. CSR 0x10 has 0x020 in it and CSR 0x13 has 0x100400. The RSU IP appears to add these together to make a new load-address. Do I need to configure something else in the CSR to make it boot back to the factory-image? Thanks, John.1.4KViews0likes0CommentsRemote re-configure a Cyclone IV in Application-mode?
Is there a way to set the remote_update-core back to Factory-mode or re-configure to another image once it is in Application mode - i.e. without a power-cycle? Both my Factory & App-images have access to the remote_update-core. Device: EP4CGX22CF19 with EPCS16 in AS-mode. Q-Prime-lite 17.1.0.Solved2.4KViews0likes4Comments
