 12b | * And I'm working on something else right now. But I will come back NixOS on the RV2 later this week. | 07:24:45 |

I tried updating my VF2 to latest nixos-unstable (as of ~1 week ago) and now it won't boot...
Unhandled exception: Instruction access fault
EPC: ffffffa700140304 RA: 00000000cb55d034 TVAL: ffffffa700140304
EPC: ffffffa67359d304 RA: 000000003e9ba034 reloc adjusted
(Then a dump of the registers.)
It seems like there's something wrong with the bootloader on the EFI partition.
Switching back to the bootloader of the previous version worked.
Change that broke the system: https://github.com/AlexandreTunstall/nixos-riscv/commit/b50ef62175853684441a9e312aa12218f5be79d3
Good Nixpkgs revision: 2726f127c15a4cc9810843b96cad73c7eb39e443
Bad Nixpkgs revision: 4cba8b53da471aea2ab2b0c1f30a81e7c451f4b6
Has anyone else booted such a recent Nixpkgs version? I just ran into this problem after upgrading kernel and u-boot... I'm already using generic-extlinux-compatible though :-/ | 12:24:59 |

| iova | 12b did you end up getting anywhere with the rv2 | 05:29:14 |
| iova | think im gonna give it a go at nix-ifying it tomorrow if i have time | 05:29:42 |
| 12b | No, I was too busy with other things to focus on that. | 06:01:22 |
 @roedimqf:ruhr-uni-bochum.de | 12b: just pushed https://github.com/sehraf/x1-riscv-arch-image-builder
Currently get's into kernel but (probably?) hangs without working console | 10:10:24 |

| cbobrobison | Is anyone here interested in Nix x RISC-V TEEs? Like Keystone, SPEAR-V, or Penglai?

| Michal | How is NixOS with the VisionFive2 currently? Just had it arrive earlier today and was thinking of NixOS-ing it :) | 19:07:00 |
 Tristan Ross | It's okay | 19:11:53 |
| Tristan Ross | RISC-V right now isn't as stable | 19:12:03 |
| Tristan Ross | Even the new P550 has issues so don't expect there to not be any problems | 19:12:28 |
| Tristan Ross | It boots at least | 19:12:33 |
| Michal | Right, of course, I meant in terms of RISC-V :) stable in my eyes means I can get it to boot, and maybe boot a second time haha | 19:12:38 |
| Tristan Ross | Yeah, NVME boot doesn't work when I've tried | 19:13:04 |
| Tristan Ross | I've got an odd problem where the DMA for the NIC driver fails to initialize so I get random network disconnects when the RX starts receiving too much. | 19:13:52 |
| Michal | Hm interesting thing to look out for then, I'm going to be using SD boot regardless so hopefully I don't have too many issues | 19:15:55 |
| Tristan Ross | SD boot is okay but not as performant | 19:17:06 |
| Tristan Ross | Even with the JH7110's lack of performance, it probably doesn't help lol | 19:17:30 |
| Michal | Yeah, wouldn't expect it to be crazy, can it boot from an EMMC module fine-ish? I do recall seeing space for one when putting the case on it | 19:18:19 |
