Step2.v not working #7

Hello

I am trying out the Amaranth RISC-V steps you made here, and trying to see if it works on the ULX3S board. I also have a TangNano9k so I first tried it out with that, but I ran into a problem where Amaranth 0.5 has nextpnr-gowin while Amaranth 0.6 has nextpnr-himbaechel and overall I can't seem to find a good installation of nextpnr-gowin. So I tried the code with Amaranth 0.6, and step1.v gives me 5 "blinking" leds, I mean they are constantly ON because of the frequency.

But step2.v gives me all LEDS OFF, on the ULX3S and on the TangNano9k boards.
