So 4 partitions:
- SPL (u-boot metadata)
- u-boot (flat binary)
- boot (FAT)
- root
Makes sense. Exactly! | 17:44:44 |
| Pratham Patel | But be vary of the sectors where the partions start and end | 17:44:56 |
| Pratham Patel | There's a reason why my script starts the first partition at 4096 ;) | 17:45:19 |
 Alex | Oh does the bootloader expect the partitions to be at specific offsets? | 17:45:20 |
| Pratham Patel | Yes :) | 17:45:48 |
| Pratham Patel | But that's the ZSBL so it won't ever change | 17:46:03 |
| Pratham Patel | That's permanent now. For better or for worse | 17:46:12 |

$ cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00001000 "spl"
mtd1: 00300000 00001000 "uboot"
mtd2: 00100000 00001000 "data"
mtd0 has a size of 128KiB, but the latest versions of u-boot exceed that. Nothing like this, where the partition table layout breaks ;) | 17:46:46 |
| Pratham Patel | Would it be feasible to create an "installer image" for RISC-V that is similar to what one gets for x86/arm64 from nixos.org? | 18:00:20 |

Would it be feasible to create an "installer image" for RISC-V that is similar to what one gets for x86/arm64 from nixos.org? It could be, but it wouldn't be very useful considering that building natively would require building 800+ derivations (and I think the kernel alone would need >20GiB of disk space while building). | 18:01:43 |
| Pratham Patel | No community supported caches until RISC-V support is merged in "mainline"? | 18:02:37 |
| Pratham Patel | My current archlinux image uses a binary cache from an arch maintainer. Arch is x86-only, while I belive NixOS isn't x86-only :) | 18:03:30 |
| Alex | It isn't, but NixOS only has official caches for {x86_64,aarch64}-{linux,darwin} | 18:04:19 |
| Alex | In reply to @thefossguy:matrix.org
No community supported caches until RISC-V support is merged in "mainline"? Essentially, community-supported caches are the only option.
Unless someone's already gone to the trouble of building a riscv64 cache, you're out of luck. | 18:05:10 |
 [0x4A6F] | We also need powerful builders to fill these caches... | 18:05:12 |
| Pratham Patel | ah I understand it now | 18:05:40 |
| Pratham Patel | until now, I was looking for a "third party repo" which I could depend on for having riscv binaries and just pull them | 18:06:05 |
| Alex | Yeah 80k+ packages aren't going to build overnight on a quad-core 1GHz processor | 18:06:09 |
| Pratham Patel | Are they really 80k+ different packages? | 18:06:36 |
| Pratham Patel | Imagine the hardwork in just bumping their versions lol | 18:06:51 |
| Alex | Yes. 120k if we count versions across all supported platforms.

Imagine the hardwork in just bumping their versions lol There are bots, which do the "hard" part... | 18:09:11 |
| Pratham Patel | Makes sense. :) | 18:09:33 |

 Leon | Are folks invested in the Milk-V Pioneer yet? It looks to good to be true... | 18:09:47 |

until now, I was looking for a "third party repo" which I could depend on for having riscv binaries and just pull them There are some but you won't find much beyond the essentials or anything the cache's maintainer has bothered to build. | 18:10:01 |

Are folks invested in the Milk-V Pioneer yet? It looks to good to be true... There are two people in China who have it already | 18:10:11 |

There are some but you won't find much beyond the essentials or anything the cache's maintainer has bothered to build. e.g. https://github.com/misuzu/nixos-vf2/blob/450d1899dc25b61d9bbb339ff8b235cbe81f19dd/flake.nix#L3 | 18:10:37 |

Are folks invested in the Milk-V Pioneer yet? It looks to good to be true... Not enough funds, maybe NixOS foundation could chim in. Maybe raitobezarius has some better understanding of this platform. | 18:10:44 |
| Pratham Patel | One is the aforementioned official Arch Linux maintainer who maintains a riscv "fork" (because archlinux is x86-only) and I've seen the other guy in StarFive's forums creating images with various distros for the VF1 | 18:11:13 |
