Simple blinky does not work on tangnano9k about apicula HOT 4 OPEN

What is the result of running these images for you?
And please send out/blinky.json, out/pnrblinky.json, out/shift.json and out/pnrshift.json (Himbaechel ones)

from apicula.

I continued my experiments - I made virtual Linux, took the current OSS and compiled not even Himbaechel, but legacy blinky. I copied steps 1 2 3 from your text literally.
out.zip

Next, I took my poor damaged tangnano9k, hoping that it wouldn’t burn anything for me

Thank You for Your efforts. I will redo my experiments locally.
I think I miss something. But I do not know what yet.
Besides that, I must admit, Your images for blinky and shifter work on my tangnano9k properly.
PS: Do You know any tool which can be used to view json files out of Yosys as a schema?
And also same graph viewer for json from nextpnr.
I was trying to use nexpnr with flag "--gui" but it crashes for me.

You can experiment with this solution:
YosysHQ/nextpnr#1255

Sorry, but there are not enough hands to keep the GUI up to date, especially since it is focused on legacy, and for Himbaechel a lot will have to be changed.

But you can send your json (both synth and pnr) here - I'll take a look.
