IceStudio with BlackIce MX

Alwil 2020-06-07 18:23:44 UTC #21

Where does Icestudio get its PCFs from? The pcf in my icestudio folder seems fine, as well as the one that is inside the application package contents under resources/boards/blackice-mx . But when I export the pcf of a project for which the currently selected board is blackice-mx, the pcf comes out with the wrong assignments. However I cannot locate where Icestudio is getting these assignments from. If i could I would just go ahead and change them. Any hints?

Nevermind. I was reading the pin out schematic wrong... I can now upload my Icestudio Designs manually with cat. APIO upload still does not work, but at least I have a workflow going! Thanks to everyone for the help.

The only think I can think of here is that APIO isn't just uploading but is rebuilding it incorrectly, try a raw upload command and maybe some of it's options to see if that makes any difference.

I've tried the upload command with various verbose settings. Interestingly the --verbose-arachne fails.

I do :
apio upload --verbose-arachne

and get:
Error: no such option: --verbose-arachne

-v, and --verbose-yosys complete without errors, but my design is not getting uploaded. I can see in these modes that the blackice-prog is appropriately addressed.

Perhaps something is wrong with arachne-pnr?
