| fufexan | my board came today 😄 | 10:21:16 |
| fufexan | sadly can't test it as I don't have a HDMI monitor lying around, nor HDMI->VGA adapter. also no USB-C multiplexer (if it can even output over usb-c).
I'll look into it more when I get hold of one of those things, or after my exam session ends (late June) | 10:22:37 |
 j-k | you can use ssh

or usb to serial

mine arrived today and a few fellow hackers immediately got interested when I unpacked it hehehe | 19:54:10 |

maybe a dumb question, did you use thermal paste for the heatsink? Another dumb one, assuming this is about VisionFive: the heatsink? Are they shipping the board with a heatsink now? | 20:08:01 |

| ius | Also: rebased my branch about ~two months forward, which resulting in exciting new failures (probably qemu bugs): e.g. a free() related test of coreutils which consistently fails - let me know if someone has spent any effort debugging it. | 20:13:30 |

| matthewcroughan - nix.how | j-k: Zhaofeng Li did you know that nix build nixpkgs#pkgsCross.riscv64.pkgsStatic.nix works? | 12:24:46 |
| matthewcroughan - nix.how | not only cross compiling, but statically compiling too | 12:25:01 |
| matthewcroughan - nix.how | * not only cross compiling, but statically linking too | 12:32:38 |
| matthewcroughan - nix.how | I just the result to fufexan, he ran it on Fedora on the VisionFive board, it worked. | 12:35:44 |
| fufexan | should've mentioned, I haven't run it on the board yet | 12:36:08 |
| fufexan | I'm leaving for another city soon so it's packed rn | 12:36:36 |
| matthewcroughan - nix.how | ah okay, so the screenshot you sent was through binfmt on an x86 box? | 12:36:38 |
| fufexan | yes | 12:36:41 |
| matthewcroughan - nix.how | If it doesn't work when it gets there then I'll be very surprised :P | 12:36:51 |
| fufexan | I'll run it real quick to test | 12:36:51 |

Download image.png | 12:40:25 |
| fufexan | sure enough, it works | 12:40:32 |
| matthewcroughan - nix.how | The blog post I write this month, is going to be amazing. | 12:44:30 |
| matthewcroughan - nix.how | Statically linking and cross compiling Nix itself for usage on any distribution for the VisionFive board is so simple, I'm just blown away. | 12:44:59 |
