| tcal | gatecat: status update: I have built a single-LED blinky with yosys/nextpnr-nexus for our LIFCL-17 board, but no signs of life on the board. I even tried driving the LED with const 1'b1 (it's active high, confirmed with a Radiant build), still no luck. If you have any hunches, I can try out different things. If it's useful, I can send you the fasm for the const-1 design. I'm checking if it's possible to get you | 17:31 |
| tcal | hardware. | 17:31 |
| gatecat | yes, the fasm would be useful, as would be the know working .bit from Radiant | 17:31 |
| gatecat | *known working | 17:31 |
| mithro | rj: It isn't currently but it should be pretty easy to get everything part from the PCIe bits... | 17:41 |
| mithro | rj: I think https://github.com/SymbiFlow/symbiflow-arch-defs/issues/1800 is solved now? | 17:43 |

| tcal | gatecat: with your fixes --- const1:WORKING blinky:WORKING litex ledchaser:WORKING | 20:19 |
| gatecat | that's good progress! | 20:20 |
| gatecat | thanks for testing | 20:20 |
| tcal | I had to modify blinky source -- the OSC_CORE needed parameter `.HF_OSC_EN("ENABLED")` | 20:20 |
| gatecat | Ah, that can be fixed on the nextpnr side so it is set automatically by default | 20:21 |
| tcal | (I got this from the LiteX Verilog -- happy accident, I accidentally tried the Litex build FIRST, and got a blinking LED) | 20:21 |

| gatecat | can you send the Radiant bitstream for LiteX to compare with ? | 20:24 |
| *** kgugala has quit IRC | 20:26 | |

| gatecat | tcal: I've also merged that PR and pushed a couple more small fixes to nextpnr master, so when you next have a chance to try it might be worth trying litex again with that pulled | 20:36 |

| ROHIT | Hi! I am a beginner programmer who wants to gain experience through open sourced projects and gain I know basics regarding python and C++ but in general I have little to know experience and I only know the very basics that you learn from beginner's textbooks, however, I am more than willing to learn. I probably know too little to start | 20:40 |
| ROHIT | contributing. Can you tell me what I should learn and beyond basic variables and functions to be able to be helpful here? | 20:40 |
