 fgaz | gcc is broken in staging
gcc-13.2.0/libgcc/config/riscv/value-unwind.h:32: Error: unrecognized opcode `0xc2202573'
I don't understand why it tries to do that when we set the architecture to riscv64gc | 14:14:11 |

I don't understand why it tries to do that when we set the architecture to riscv64gc NB: According to the RISC-V ISA manual (V20211203), that is a CSRRS instruction on CSR 0xc22, which is a standard read-only unprivileged CSR that hasn't yet been allocated. Whatever is generating that instruction probably should not.
If you don't need CSRs, disabling Zicsr may help. | 13:23:25 |

| pouspous | Hi guys. I recently bought a Star64 and wanted to try NixOS on it. I cloned https://git.sr.ht/~fgaz/nixos-star64 and added a line networking.wireless.networks."my-wifi" = {}; before running nix build and flashing the result image onto a sd card.
Once the sd card inserted and the Star64 plugged to the power, the usual green light lights up, but no connection is made on the wireless wifi. I have also tried flashing the image onto an eMMC, but to no avail. I don't even know if the system has booted or if it in a stale state or something. Do you know any way to make the light blink once the system is booted ? | 14:51:59 |

Do you know any way to make the light blink once the system is booted ? the light won't blink by default, you can write a target to /sys/devices/platform/leds/leds/blue-led/trigger to enable it. for some reason I don't get the always blinking target on the latest version, but mmc0/mmc1 works | 10:19:07 |
| fgaz | make sure you update the firmware and set the dip switches to flash to rule out any problem with those | 10:20:30 |
| pouspous | everything works now, thanks ! looks like wireless didn't work out of the box so I just plugged an ethernet cable to it (I couldnt do it earlier on) | 14:37:59 |
| fgaz | Nice! | 14:48:34 |

I think I discovered what happened, our riscv bootstrap files have never been updated so we are stuck with an old assembler that doesn't recognize rvv 1.0 instructions. | 14:56:15 |
| fgaz | Now, how do I generate a bootstrap tarball and who do I ping to get it uploaded to tarballs.nixos.org? This doesn't seem to be documented anywhere | 14:57:03 |
 raitobezarius | it's documented in stdenv | 14:57:27 |
| raitobezarius | ping lovesegfault IIRC on #stdenv:nixos.org for upload | 14:57:51 |
| fgaz | aha, I found make-bootstrap-tools | 14:58:24 |
| fgaz | raitobezarius: will do thanks | 14:58:35 |

cache for RISC-V when ;P an official one? when suitable (ie. rack-mountable) hardware is available | 16:18:20 |
| fgaz | there are a few unofficial ones already, I'll probably make one as well | 16:18:51 |
| fgaz | * an official one? when suitable (ie. rack-mountable) hardware is available, see https://pad.lassul.us/NixOS-riscv64-linux-2023-09-10# | 16:20:37 |

| nyanbinary | I mean RISC-V is becoming more prevalent so thats good | 16:41:28 |
