Is it a bug or did i something wrong? i use OSS CAD Suite

GW1NR-9 and GW1NR-9C are different chips, but they have the same model number. So that's the trouble. You make an image for 9 and try to flash it to 9C. As a quick fix, you can try it: gowin_pack -d GW1N-9C .......

And nextpnr should also be called for this family: --device GW1NR-LV9QN88PC6/I5 --family GW1N-9C

Thanks it works!

Should we add this info somewhere, from a beginner like me, it's hard to find these things out

Here is the updated command: yosys -D LEDS_NR=6 -p "read_verilog blinky.v; synth_gowin -json blinky.json" nextpnr-gowin --json blinky.json \ --write pnrblinky.json \ --device GW1NR-LV9QN88PC6/I5 --family GW1N-9C \ --cst tangnano9k.cst gowin_pack -d GW1N-9C -o pack.fs pnrblinky.json openFPGALoader -b tangnano9k pack.fs
