 Mic92 | to tarballs.nixos.org? | 13:23:24 |
 Pratham Patel (you can mention me) | I'm not sure. Only now starting to understand Nix after being 1+ years in the Nix ecosystem lol | 13:23:57 |
| Pratham Patel (you can mention me) | Okay, my custom minimal ISO started building :) | 13:24:25 |

Can we not also upload our own cross-compiled ghc binary tarball? That is definitely worth discussing with the Nixpkgs maintainers, but it'd be easier once the changes that enable cross-compilation of GHC are merged.
The PRs that enable it also add x86_64 -> riscv64 cross-compilation to Hydra to catch regressions. | 13:24:49 |
| Alex | So once the changes are merged, the Hydra build could be downloaded and packaged into a tarball to bootstrap native builds (or, more likely, used to package a complete native build). | 13:26:05 |
| Mic92 | Also sounds good to me. | 13:26:24 |
| Alex | The newest PR for this is: https://github.com/NixOS/nixpkgs/pull/305392
(It works already, but I think sterni might want to make a few changes before it is merged?) | 13:27:50 |

 hexa | all of them? | 19:30:40 |
| atka | well the boards I ordered :), first time hands on with real hardware | 20:23:30 |
 [0x4A6F] | Nice, have fun. Which boards do you hav? | 20:54:54 |
| [0x4A6F] | * Nice, have fun. Which boards do you have? | 20:55:02 |
| atka | [0x4A6F]: two milk-v duo 64M, 1x milk-v duo 256M, and an ethernet/io board | 21:30:13 |

| atka | Nick Cao: thanks for the work on the Duo64 and Duo256! | 21:30:26 |
| atka | is ION size supposed to be set to zero by default for these images? | 21:39:56 |

is ION size supposed to be set to zero by default for these images? Yes, but requires a custom built fip.bin | 01:41:50 |
| Nick Cao | In reply to @nickcao:nichi.co
Yes, but requires a custom built fip.bin It seems the one we are using already have ION size set to 0: https://github.com/mcdonc/duo-buildroot-sdk/tree/nixos-riscv | 01:43:00 |
| Nick Cao | In reply to @nickcao:nichi.co
Yes, but requires a custom built fip.bin * It seems the one we are using can't have ION size set to 0: https://github.com/mcdonc/duo-buildroot-sdk/tree/nixos-riscv for some reason. | 01:43:27 |
